127-804: South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere , with a considerably smaller portion in the Northern Hemisphere . It can also be described as the southern subregion of the Americas . South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean ; North America and the Caribbean Sea lie to

254-764: A canal across the isthmus, with some favoring a canal across Nicaragua and others advocating the purchase of the French interests in Panama. Bunau-Varilla , who was seeking American involvement, asked for $ 100 million, but accepted $ 40 million in the face of the Nicaraguan option. In June 1902, the US Senate voted in favor of the Spooner Act , to pursue the Panamanian option, provided the necessary rights could be obtained. On 22 January 1903,

381-688: A canal. Numerous canals were built in other countries in the late 18th and early 19th centuries. The success of the Erie Canal through central New York in the United States in the 1820s and the collapse of the Spanish Empire in Latin America resulted in growing American interest in building an inter-oceanic canal. Beginning in 1826, US officials began negotiations with Gran Colombia (present-day Colombia, Venezuela, Ecuador, and Panama), hoping to gain

508-523: A concession to build a canal. Jealous of their newly gained independence and fearing domination by the more powerful United States, president Simón Bolívar and New Granada officials declined American offers. After the collapse of Gran Colombia, New Granada remained unstable under constant government intrigue. Great Britain attempted to develop a canal in 1843. According to the New-York Daily Tribune , 24 August 1843, Barings Bank of London and

In 1822 the two men met at the Guayaquil Conference in Ecuador, where they failed to agree on governance strategies for the liberated nations. Two years later Bolívar's forces beat the Spanish at the Battle of Ayacucho , securing the independence of Peru and the rest of South America. In

762-579: A high worker mortality rate . The US took over the project in 1904 and opened the canal in 1914. The US continued to control the canal and surrounding Panama Canal Zone until the Torrijos–Carter Treaties provided for its handover to Panama in 1977. After a period of joint American–Panamanian control, the Panamanian government took control in 1999. It is now managed and operated by the Panamanian government-owned Panama Canal Authority . The original locks are 33.5 meters (110 ft) wide and allow

889-449: A long history of colonialism , the overwhelming majority of South Americans speak Spanish or Portuguese , and societies and states are rich in Western traditions . Relative to Africa, Asia, and Europe, post-1900 South America has been a peaceful continent with few wars, although high rates of violent crime remain a concern in some countries. South America occupies the southern portion of

In the Atlantic Ocean, Brazil administers Fernando de Noronha , Trindade and Martim Vaz , and the Saint Peter and Saint Paul Archipelago , while the Falkland Islands (Spanish: Islas Malvinas ) and South Georgia and

1143-611: A sea-level canal (like the Suez), but he visited the site only a few times, during the dry season which lasts only four months of the year. His men were unprepared for the rainy season, during which the Chagres River , where the canal started, became a raging torrent, rising up to 10 m (33 ft). The dense jungle was alive with venomous snakes, insects, and spiders, but the worst challenges were yellow fever , malaria , and other tropical diseases, which killed thousands of workers; by 1884,

1270-572: A sea-level canal, as had been attempted by the French and temporarily abandoned by them in 1887 for a ten locks system designed by Philippe Bunau-Varilla, and definitively in 1898 for a lock-and-lake canal designed by the Comité Technique of the Compagnie Nouvelle de Canal de Panama as conceptualized by Adolphe Godin de Lépinay in 1879. But in 1906 Stevens, who had seen the Chagres in full flood,

1397-691: A self-educated engineer who had built the Great Northern Railroad . Stevens was not a member of the ICC; he increasingly viewed its bureaucracy as a serious hindrance, bypassing the commission and sending requests and demands directly to the Roosevelt administration in Washington, DC. One of Stevens' first achievements in Panama was in building and rebuilding the housing, cafeterias, hotels, water systems, repair shops, warehouses, and other infrastructure needed by

1524-583: A settlement began and resulted in the Torrijos–Carter Treaties . On 7 September 1977, the treaty was signed by President of the United States Jimmy Carter and Omar Torrijos , de facto leader of Panama. This mobilized the process of granting the Panamanians free control of the canal so long as Panama signed a treaty guaranteeing the permanent neutrality of the canal. The treaty led to full Panamanian control effective at noon on 31 December 1999, and

1651-481: A site called Chavín de Huantar in modern Peru at an elevation of 3,177 meters (10,423 ft). Chavín civilization spanned 900 BC to 300 BC. In the central coast of Peru, around the beginning of the 1st millennium AD, Moche (100 BC – 700 AD, at the northern coast of Peru), Paracas and Nazca (400 BC – 800 AD, Peru) cultures flourished with centralized states with permanent militia improving agriculture through irrigation and new styles of ceramic art. At

1778-670: A subtropical climate of the dinaric type. At the highest points of the Andean region, climates are colder than the ones occurring at the highest point of the Norwegian fjords. In the Andean plateaus, the warm climate prevails, although it is tempered by the altitude, while in the coastal strip, there is an equatorial climate of the Guinean type. From this point until the north of the Chilean coast appear, successively, Mediterranean oceanic climate , temperate of

1905-581: A treaty, in the name of the Société civile internationale du Canal interocéanique par l'isthme du Darien headed by general Étienne Türr, with the Colombian government, known as the Wyse concession, to build an interoceanic canal through Panama. The first attempt to construct a canal through what was then Colombia's province of Panama began on 1 January 1881. The project was inspired by the diplomat Ferdinand de Lesseps , who

2032-538: Is an artificial 82-kilometer (51-mile) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean , cutting across the Isthmus of Panama , and is a conduit for maritime trade. Locks at each end lift ships up to Gatun Lake , an artificial fresh water lake 26 meters (85 ft) above sea level , created by damming up the Chagres River and Lake Alajuela to reduce the amount of excavation work required for

2159-514: Is because the most extensive part of the continent is in the equatorial zone (the region has more areas of equatorial plains than any other region), therefore giving the Southern Cone more oceanic influence, which moderates year round temperatures. The average annual temperatures in the Amazon basin oscillate around 27 °C (81 °F), with low thermal amplitudes and high rainfall indices. Between

2286-459: Is by far the most populous South American country, with almost half of the continent's population, followed by Colombia, Argentina, Venezuela, and Peru. In recent decades, Brazil has also generated half of the continent's GDP and has become the continent's first regional power. Most of the population lives near the continent's western or eastern coasts while the interior and the far south are sparsely populated. The geography of western South America

2413-597: Is dominated by the Andes mountains; in contrast, the eastern part contains both highland regions and vast lowlands where rivers such as the Amazon , Orinoco and Paraná flow. Most of the continent lies in the tropics, except for a large part of the Southern Cone located in the middle latitudes . The continent's cultural and ethnic outlook has its origin with the interaction of Indigenous peoples with European conquerors and immigrants and, more locally, with African slaves . Given

2540-595: Is now Colombia. They established the Muisca Confederation of many clans, or cacicazgos , that had a free trade network among themselves. Many were goldsmiths and farmers. Other important Pre-Columbian cultures include: the Cañaris (in south central Ecuador), Chimú Empire (1300–1470, Peruvian northern coast), Chachapoyas , and the Aymaran kingdoms (1000–1450, Western Bolivia and southern Peru). Holding their capital at

2667-475: Is one of the most biodiverse continents on Earth. It is home to many unique species of animals including the llama , anaconda , piranha , jaguar , vicuña , and tapir , and to one of the largest known insects in the world, the Titan beetle . The Amazon rainforests possess high biodiversity , with Brazil estimated to contain 10% of Earth's species . 83% of South America's large mammals ( megafauna ) became extinct at

2794-402: Is sometimes misinterpreted as the "99-year lease" because of misleading wording included in article 22 of the agreement. Almost immediately, the treaty was condemned by many Panamanians as an infringement on their country's new national sovereignty. This would later become a contentious diplomatic issue among Colombia, Panama, and the United States. President Roosevelt famously stated, "I took

2921-569: Is the largest country in South America, covering a little less than half of the continent's land area and encompassing around half of the continent's population. The remaining countries and territories are divided among four subregions : the Andean states , Caribbean South America , The Guianas , and the Southern Cone . Physiographically, South America also includes some of the nearby islands. The Dutch ABC islands ( Aruba , Bonaire , and Curaçao ),

3048-510: The Altiplano , Tiahuanaco or Tiwanaku (100 BC – 1200 AD, Bolivia) managed a large commercial network based on religion. Around the 7th century, both Tiahuanaco and Wari or Huari Empire (600–1200, Central and northern Peru) expanded its influence to all the Andean region, imposing the Huari urbanism and Tiahuanaco religious iconography. The Muisca were the main indigenous civilization in what

3175-569: The Archipelago of San Andrés, Providencia and Santa Catalina ( San Andrés Island , Providencia Island , and Santa Catalina Island etc., which are administered by Colombia ) are politically parts of South American countries but physiographically parts of North America. Other islands often associated with geopolitical South America are the Chiloé Archipelago and Robinson Crusoe Island (both administered by Chile), Easter Island (culturally

They migrated south through North America, and eventually reached South America through the Isthmus of Panama . Amongst the oldest evidence for human presence in South America is the Monte Verde II site in Chile, suggested to date to around 14,500 years ago. From around 13,000 years ago,

3556-617: The Caribbean colonies and Brazil, as European nations built up economically slave-dependent colonies in the New World . Nearly 40% of all African slaves trafficked to the Americas went to Brazil. An estimated 4.9 million slaves from Africa came to Brazil during the period from 1501 to 1866. In contrast to other European colonies in the Americas which mainly used the labor of African slaves, Spanish colonists mainly enslaved indigenous Americans. In 1750,

3683-540: The Culebra Cut , valued at about $ 1.00 per cubic yard. The United States also paid the new country of Panama $ 10 million and a $ 250,000 payment each following year. In 1921, Colombia and the United States entered into the Thomson–Urrutia Treaty , in which the United States agreed to pay Colombia $ 25 million: $ 5 million upon ratification, and four $ 5 million annual payments, and grant Colombia special privileges in

3810-463: The Fishtail projectile point style became widespread across South America, with its disappearance around 11,000 years ago coincident with the disappearance of South America's megafauna. Maize was present in northern South America by around 6,000 years ago. By 2000 BC, many agrarian communities had been settled throughout the Andes and the surrounding regions. Fishing became a widespread practice along

4064-752: The Hay–Herrán Treaty was signed by United States Secretary of State John M. Hay and Colombian Chargé Tomás Herrán . For $ 10 million and an annual payment, it would have granted the United States a renewable lease in perpetuity from Colombia on the land proposed for the canal. The treaty was ratified by the US Senate on 14 March 1903, but the Senate of Colombia unanimously rejected the treaty since it had become significantly unpopular in Bogotá due to concerns over insufficient compensation, threat to sovereignty, and perpetuity. Roosevelt changed tactics, based in part on

Shortly after recognizing Panama, he signed a treaty with the new Panamanian government under terms similar to the Hay–Herrán Treaty. On 2 November 1903, US warships blocked sea lanes against possible Colombian troop movements en route to put down the Panama rebellion. Panama declared independence on 3 November 1903. The United States quickly recognized

4572-627: The Mallarino–Bidlack Treaty , negotiated between the US and New Granada, granted the United States transit rights and the right to intervene militarily in the isthmus. In 1848, the discovery of gold in California , on the West Coast of the United States, generated renewed interest in a canal crossing between the Atlantic and Pacific oceans.

The Pacific coast of Colombia and northern Ecuador are rainy regions, with Chocó in Colombia being the rainiest place in the world along with the northern slopes of Indian Himalayas. The Atacama Desert, along this stretch of coast, is one of the driest regions in the world. The central and southern parts of Chile are subject to extratropical cyclones , and most of

4953-533: The Panama Canal Authority (ACP) assumed command of the waterway. The Panama Canal remains one of the chief revenue sources for Panama. Before this handover, the government of Panama held an international bid to negotiate a 25-year contract for operation of the container shipping ports located at the canal's Atlantic and Pacific outlets. The contract was not affiliated with the ACP or Panama Canal operations and

5080-480: The Portuguese Crown abolished the enslavement of indigenous peoples in colonial Brazil , under the belief that they were unfit for labor and less effective than enslaved Africans. Enslaved Africans were brought to the Americas on slave ships , under inhuman conditions and ill-treatment, and those who survived were sold in slave markets . After independence, all South American countries maintained slavery for some time. The first South American country to abolish slavery

5334-475: The Republic of New Granada entered into a contract for the construction of a canal across the Isthmus of Darien (Isthmus of Panama). They referred to it as the Atlantic and Pacific Canal, and it was a wholly British endeavor. Projected for completion in five years, the plan was never carried out. At nearly the same time, other ideas were floated, including a canal (and/or a railroad) across Mexico's Isthmus of Tehuantepec . That did not develop, either. In 1846,

The Juntas, in both Spain and the Americas, promoted the ideas of the Enlightenment . Five years after the beginning of the war, Ferdinand VII returned to the throne and began the Absolutist Restoration , as the royalists got the upper hand in

5842-426: The cargo ship SS  Ancon . The opening of the Panama Canal in 1914 caused a severe drop in traffic along Chilean ports due to shifts in maritime trade routes, despite the closure of the canal for nearly seven months after a landslide in the Culebra Cut on 18 September 1915. The burgeoning sheep farming business in southern Patagonia suffered a significant setback by the change in trade routes, as did

5969-712: The native populations had no immune resistance – caused large-scale depopulation of the native population under Spanish control. Systems of forced labor, such as the haciendas and mining industry's mit'a also contributed to the depopulation. After this, enslaved Africans , who had developed immunities to these diseases, were quickly brought in to replace them. The Spaniards were committed to converting their native subjects to Christianity and were quick to purge any native cultural practices that hindered this end; however, many initial attempts at this were only partially successful, as native groups simply blended Catholicism with their established beliefs and practices. Furthermore,

6096-655: The 30 million cu yd (23 million m ) excavated by the French. As quickly as possible, the Americans replaced or upgraded the old, unusable French equipment with new construction equipment that was designed for a much larger and faster scale of work. 102 large, railroad-mounted steam shovels were purchased, 77 from Bucyrus-Erie , and 25 from the Marion Power Shovel Company . These were joined by enormous steam-powered cranes, giant hydraulic rock crushers , concrete mixers , dredges , and pneumatic power drills, nearly all of which were manufactured by new, extensive machine-building technology developed and built in

6223-452: The Americas in order to ease the voyage for ships traveling between Spain and Peru. The Spanish were seeking to gain a military advantage over the Portuguese. In 1668, the English physician and philosopher Sir Thomas Browne speculated in his encyclopedic work, Pseudodoxia Epidemica , that "some Isthmus have been eaten through by the Sea, and others cut by the spade: And if the policy would permit, that of Panama in America were most worthy

6350-456: The Americas. The continent is generally delimited on the northwest by the Darién watershed along the Colombia–Panama border , although some may consider the border instead to be the Panama Canal . Geopolitically and geographically, all of Panama – including the segment east of the Panama Canal in the isthmus – is typically included in North America alone and among the countries of Central America . Almost all of mainland South America sits on

6477-445: The Argentine Patagonia is desert . In the Pampas of Argentina, Uruguay and South of Brazil the rainfall is moderate, with rains well distributed during the year. The moderately dry conditions of the Chaco oppose the intense rainfall of the eastern region of Paraguay. In the semiarid coast of the Brazilian Northeast the rains are linked to a monsoon regime. Important factors in the determination of climates are sea currents, such as

6604-477: The Breton type and, already in Tierra del Fuego , cold climate of the Siberian type. The distribution of rainfall is related to the regime of winds and air masses. In most of the tropical region east of the Andes, winds blowing from the northeast, east and southeast carry moisture from the Atlantic, causing abundant rainfall. However, due to a consistently strong wind shear and a weak Intertropical Convergence Zone , South Atlantic tropical cyclones are rare. In

6731-400: The Canal Zone. In return, Colombia recognized Panama as an independent nation. The US formally took control of the canal property on 4 May 1904, inheriting from the French a depleted workforce and a vast jumble of buildings, infrastructure, and equipment, much of it in poor condition. A US government commission, the Isthmian Canal Commission (ICC), was established to oversee construction; it

6858-429: The Chagres River above Gatun Lake. Completed in 1935, the dam created Madden Lake (later Alajuela Lake), which provides additional water storage for the canal. In 1939, construction began on a further major improvement: a new set of locks large enough to carry the larger warships that the United States was building at the time and planned to continue building. The work proceeded for several years, and significant excavation

On 6 November 1903, Philippe Bunau-Varilla, as Panama's ambassador to the United States, signed the Hay–Bunau-Varilla Treaty , granting rights to the United States to build and indefinitely administer the Panama Canal Zone and its defenses. This

7112-412: The French manager of the New Panama Canal Company, eventually managed to persuade Lesseps that a lock-and-lake canal was more realistic than a sea-level canal. The Comité Technique, a high level technical committee, was formed by the Compagnie Nouvelle to review the studies and work—that already finished and that still ongoing—and come up with the best plan for completing the canal. The committee arrived on

7239-534: The Isthmus in February 1896 and went immediately, quietly and efficiently about their work of devising the best possible canal plan, which they presented on 16 November 1898. Many aspects of the plan were similar in principle to the canal that was finally built by the Americans in 1914. It was a lock canal with two high level lakes to lift ships up and over the Continental Divide. Double locks would be 738 feet long and about 30 feet deep (225 m × 9 m); one chamber of each pair would be 82 feet (25 m) wide,

7366-407: The Isthmus, started the canal and then left Congress not to debate the canal, but to debate me." Several parties in the United States called this an act of war on Colombia: The New York Times described the support given by the United States to Bunau-Varilla as an "act of sordid conquest". The New York Evening Post called it a "vulgar and mercenary venture". The US maneuvers are often cited as

7493-457: The Pacific mail steamships at around the same time, benefited from the gold discovery. Aspinwall's route included steamship legs from New York City to Panama, and from Panama to California, with an overland portage through Panama. This route with an overland leg in Panama was soon frequently traveled, as it provided one of the fastest connections between San Francisco, California, and the East Coast cities, about 40 days' transit in total. Nearly all

The later canal route was constructed parallel to it, as it had helped clear dense forests. An all-water route between the oceans was still the goal. In 1855, William Kennish , a Manx -born engineer working for the United States government, surveyed

8001-830: The Spaniards brought their language to the degree they did with their religion, although the Roman Catholic Church 's evangelization in Quechua , Aymara , and Guaraní actually contributed to the continuous use of these native languages albeit only in the oral form. Eventually, the natives and the Spaniards interbred, forming a mestizo class. At the beginning, many mestizos of the Andean region were offspring of Amerindian mothers and Spanish fathers. After independence, most mestizos had native fathers and European or mestizo mothers. Many native artworks were considered pagan idols and destroyed by Spanish explorers; this included many gold and silver sculptures and other artifacts found in South America, which were melted down before their transport to Spain or Portugal. Spaniards and Portuguese brought

Napoleon captured King Ferdinand VII of Spain, and appointed his own brother instead. This appointment provoked popular resistance, which created Juntas to rule in the name of the captured king. Many cities in the Spanish colonies, however, considered themselves equally authorized to appoint local Juntas like those of Spain. This began

8255-400: The US army troops that were supporting the Panamanian rebels. The reason an army of conscripts was sent was that it was the best response the Colombians could muster, as Colombia still was recovering from a civil war between Liberals and Conservatives from October 1899, to November 1902, known as the " Thousand Days War ". The US was fully aware of these conditions and even incorporated them into

In many places, the new Gatun Lake flooded over the original rail line, and a new line had to be constructed above Gatun Lake's waterline. Between 1912 and 1914 there was a controversy about the tolls for the canal . In 1907, Stevens resigned as chief engineer. His replacement, appointed by President Theodore Roosevelt,

Given the strategic location of Panama, and the potential of its narrow isthmus separating two great oceans, other trade links in the area were attempted over the years.

9144-509: The canal was completed in 1914, 401 years after Panama was first crossed overland by the Europeans in Vasco Núñez de Balboa 's party of conquistadores . The United States spent almost $ 500 million (roughly equivalent to $ 15.2 billion in 2023) to finish the project. This was by far the largest American engineering project to date. The canal was formally opened on 15 August 1914, with the passage of

9271-616: The canal. In 2017, it took ships an average of 11.38 hours to pass between the canal's two outer locks. The American Society of Civil Engineers has ranked the Panama Canal one of the Seven Wonders of the Modern World . The earliest record regarding a canal across the Isthmus of Panama was in 1534, when Charles V , Holy Roman Emperor and King of Spain, ordered a survey for a route through

9398-406: The canal. Locks then lower the ships at the other end. An average of 200,000,000 L (52,000,000 US gal) of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around

9525-597: The classic example of US gunboat diplomacy in Latin America, and the best illustration of what Roosevelt meant by the old African adage, "Speak softly and carry a big stick [and] you will go far." After the revolution in 1903, the Republic of Panama became a US protectorate until 1939. In 1904, the United States purchased the French equipment and excavations, including the Panama Railroad , for US$ 40 million, of which $ 30 million related to excavations completed, primarily in

9652-483: The coast, helping establish fish as a primary source of food. Irrigation systems were also developed at this time, which aided in the rise of an agrarian society . South American cultures began domesticating llamas , vicuñas , guanacos , and alpacas in the highlands of the Andes circa 3500 BC. Besides their use as sources of meat and wool, these animals were used for transportation of goods. The rise of plant growing and

9779-459: The concentration in producing one, or few, major export commodities has often hindered the development and diversification of its economies. The fluctuation in the price of commodities in international markets has led historically to major highs and lows, booms and busts, in the economies of South American states, often causing political instability. This has led for calls to diversify production and increase trade within South America itself. Brazil

9906-535: The conflict. The independence of South America was secured by Simón Bolívar (Venezuela) and José de San Martín (Argentina), the two most important Libertadores . Bolívar led a great uprising in the north, then led his army south towards Lima , the capital of the Viceroyalty of Peru . Meanwhile, San Martín led an army across the Andes Mountains, along with Chilean expatriates, and liberated Chile. He organized

10033-627: The construction of tunnels and locks. A second Isthmian exploratory visit began on 6 December 1877, where two routes were explored in Panama, the San Blas route and a route from Bahía Limón to Panama City, the current Canal route. The French had achieved success in building the Suez Canal in the Middle East. While it was a lengthy project, they were encouraged to plan for a canal to cross the Panamanian isthmus. Wyse went to Bogotá and on 20 March 1878, signed

10160-665: The continental divide to connect Gatun Lake to the Pacific Panama Canal locks . On 10 October 1913, President Woodrow Wilson sent a signal from the White House by telegraph which triggered the explosion that destroyed the Gamboa Dike. This flooded the Culebra Cut, thereby joining the Atlantic and Pacific oceans via the Panama Canal. Alexandre La Valley (a floating crane built by Lobnitz & Company and launched in 1887)

10287-615: The current Humboldt and Falklands . The equatorial current of the South Atlantic strikes the coast of the Northeast and there is divided into two others: the current of Brazil and a coastal current that flows to the northwest towards the Antilles , where there it moves towards northeast course thus forming the most Important and famous ocean current in the world, the Gulf Stream . South America

10414-459: The death rate was over 200 per month. Public health measures were ineffective because the role of the mosquito as a disease vector was then unknown. Conditions were downplayed in France to avoid recruitment problems, but the high mortality rate made it difficult to maintain an experienced workforce. Workers had to continually widen the main cut through the mountain at Culebra and reduce the angles of

10541-580: The economy of the Falkland Islands . Throughout this time, Ernest "Red" Hallen was hired by the Isthmian Canal Commission to document the progress of the work. In 1914, steam shovels from the Panama Canal were purchased and put to use in Chuquicamata copper mine of northern Chile. By the 1930s, water supply became an issue for the canal, prompting construction of the Madden Dam across

10668-527: The effort, and it was abandoned in April 1700. In 1788, Americans suggested that the Spanish should build the canal, since they controlled the colonies where it would be built. They said that this would be a less treacherous route for ships than going around the southern tip of South America, and that tropical ocean currents would naturally widen the canal after construction. During an expedition from 1788 to 1793, Alessandro Malaspina outlined plans for construction of

10795-532: The end of the Pleistocene around 11,000 years ago as part of the Quaternary extinction event , among the highest of any continent, with the casualties including saber-toothed cats , ground sloths , glyptodonts , gomphotheres , the equines Hippidion and Equus neogeus , and all remaining South American native ungulates . South America is thought to have been first inhabited by humans when people were crossing

10922-502: The engineering and excavation work into three divisions: Atlantic, Central, and Pacific. The Atlantic Division, under Major William L. Sibert , was responsible for construction of the massive breakwater at the entrance to Bahía Limón , the Gatun locks , and their 3 + 1 ⁄ 2 -mile (5.6 km) approach channel, and the immense Gatun Dam. The Pacific Division, under Sydney B. Williamson (the only civilian member of this high-level team),

11049-412: The ensuing scandal, known as the Panama affair , some of those deemed responsible were prosecuted, including Gustave Eiffel . Lesseps and his son Charles were found guilty of misappropriation of funds and sentenced to five years' imprisonment. This sentence was later overturned, and the father, at age 88, was never imprisoned. In 1894, a second French company, the Compagnie Nouvelle du Canal de Panama,

11176-419: The gold that was shipped out of California went by the fast Panama route. Several new and larger paddle steamers were soon plying this new route, including private steamship lines owned by American entrepreneur Cornelius Vanderbilt that made use of an overland route through Nicaragua, and the unfortunate SS Central America . In 1850, the United States began construction of the Panama Railroad (now called

11303-650: The great city of Cusco , the Inca civilization dominated the Andes region from 1438 to 1533. Known as Tawantin suyu , and "the land of the four regions", in Quechua , the Inca Empire was highly distinct and developed. Inca rule extended to nearly a hundred linguistic or ethnic communities, some nine to fourteen million people connected by a 25,000 kilometer road system . Cities were built with precise, unmatched stonework, constructed over many levels of mountain terrain. Terrace farming

11430-466: The hemisphere. This definition excludes all of the European and African mainlands, but still includes some islands associated with these continents, more of eastern Russia and Oceania, and part of Antarctica. It includes all islands of Alaska, but excludes a small portion of northeast Greenland . There is no hemisphere that includes all of the Americas that also excludes all land outside of it, regardless of

11557-471: The island is geopolitically a part of Africa. All of the world's major climate zones are present in South America. The distribution of the average temperatures in the region presents a constant regularity from the 30° of latitude south , when the isotherms tend, more and more, to be confused with the degrees of latitude. In temperate latitudes, winters and summers are milder than in North America. This

11684-653: The islands of Trinidad and Tobago ( Trinidad Island and Tobago Island etc.), the State of Nueva Esparta , and the Federal Dependencies of Venezuela sit on the northern portion of the South American continental shelf and are sometimes considered parts of the continent. Geopolitically, all the island countries and territories in the Caribbean have generally been grouped as a subregion of North America instead. By contrast, Aves Island (administered by Venezuela ) and

11811-538: The isthmus and issued a report on a route for a proposed Panama Canal. His report was published as a book entitled The Practicability and Importance of a Ship Canal to Connect the Atlantic and Pacific Oceans . In 1876, Lucien Napoléon Bonaparte Wyse and his chief assistant Armand Réclus, both officers and engineers of the French Navy , explored several routes in the Darien-Atrato regions and made proposals including

11938-525: The land outside Europe should be an exclusive duopoly between the two countries. The treaty established an imaginary line along a north–south meridian 370 leagues west of the Cape Verde Islands , roughly 46° 37' W. In terms of the treaty, all land to the west of the line (known to comprise most of the South American soil) would belong to Spain, and all land to the east, to Portugal. As accurate measurements of longitude were impossible at that time,

12065-476: The line was not strictly enforced, resulting in a Portuguese expansion of Brazil across the meridian. Beginning in the 1530s, the people and natural resources of South America were repeatedly exploited by foreign conquistadors , first from Spain and later from Portugal. These competing colonial nations claimed the land and resources as their own and divided it into colonies. European infectious diseases ( smallpox , influenza , measles , and typhus ) – to which

12192-706: The meridian does pass Wallis and Futuna .) With the exception of the United States (due to Wake Island , Guam and the Northern Mariana Islands ), all of them are located on just one side of the International Date Line , which curves around them. The following countries and territories lie outside the Americas yet are entirely, mostly, or partially within the Western Hemisphere: Panama Canal The Panama Canal (Spanish: Canal de Panamá )

12319-533: The meridians or points chosen to define it. Below is a list of the sovereign states in both the Western and Eastern hemispheres on the IERS Reference Meridian , in order from north to south: Below is a list of additional sovereign states which are in both the Western and Eastern hemispheres along the 180th meridian , in order from north to south. (France is not listed below due to its inclusion above, though

12446-401: The mid-17th century. It became a Dutch colony in 1667. The indigenous peoples of the Americas in various European colonies were forced to work in European plantations and mines; along with enslaved Africans who were also introduced in the proceeding centuries via the slave trade . European colonists were heavily dependent on indigenous labor during the initial phases of settlement to maintain

12573-456: The new nation. This happened so quickly that by the time the Colombian government in Bogotá launched a response to the Panamanian uprising US troops had already entered the rebelling province. The Colombian troops dispatched to Panama were hastily assembled conscripts with little training. While these conscripts may have been able to defeat the Panamanian rebels, they would not have been able to defeat

12700-543: The northwest. The continent includes twelve sovereign states : Argentina , Bolivia , Brazil , Chile , Colombia , Ecuador , Guyana , Paraguay , Peru , Suriname , Uruguay , and Venezuela ; two dependent territories : the Falkland Islands and South Georgia and the South Sandwich Islands ; and one internal territory : French Guiana . The ABC islands of the Dutch Caribbean (north of Venezuela in

12827-621: The other 59 ft (18 m). There would be eight sets of locks, two at Bohio Soldado and two at Obispo on the Atlantic side; one at Paraiso, two at Pedro Miguel, and one at Miraflores on the Pacific. Artificial lakes would be formed by damming the Chagres River at Bohio and Alhajuela, providing both flood control and electric power. At this time, US President Theodore Roosevelt and the United States Senate were interested in establishing

12954-493: The passage of Panamax ships. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded waterway began commercial operation on 26 June 2016. The new locks allow transit of larger, Neopanamax ships. Annual traffic has risen from about 1,000 ships in 1914, when the canal opened, to 14,702 vessels in 2008, for a total of 333.7 million Panama Canal/Universal Measurement System (PC/UMS) tons . By 2012, more than 815,000 vessels had passed through

13081-486: The planning of the Panama intervention as the US acted as an arbitrator between the two sides. The peace treaty that ended the "Thousand Days War" was signed on the USS Wisconsin on 21 November 1902. While in port, the US also brought engineering teams to Panama with the peace delegation to begin planning the canal's construction before the US had even gained the rights to build the canal. All these factors would result in

13208-563: The project. After two years of extensive work, the mosquito-spread diseases were nearly eliminated . Despite the monumental effort, about 5,600 workers died from disease and accidents during the US construction phase of the canal. Besides healthier and far better living conditions for the workers, another benefit given to American citizens working on the Canal was a medal for two years of service. Additional bars were added for each two-year period after that. Designed by Victor D. Brenner and featuring

13335-455: The railway, which was to prove crucial in transporting millions of tons of soil from the cut through the mountains to the dam across the Chagres River. Colonel William C. Gorgas had been appointed chief sanitation officer of the canal construction project in 1904. Gorgas implemented a range of measures to minimize the spread of deadly diseases, particularly yellow fever and malaria , which had recently been shown to be mosquito-borne following

13462-413: The rainy climate. In France, Lesseps kept the investment and supply of workers flowing long after it was obvious that the targets were not being met, but eventually the money ran out. The French effort went bankrupt in 1889 after reportedly spending US$ 287,000,000; an estimated 22,000 men died from disease and accidents, and the savings of 800,000 investors were lost. Work was suspended on May 15, and in

13589-501: The slopes to minimize landslides into the canal. Steam shovels were used in the construction of the canal, purchased from Bay City Industrial Works, a business owned by William L. Clements in Bay City, Michigan . Bucket chain excavators manufactured by both Alphonse Couvreux and Wehyer & Richemond and Buette were also used. Other mechanical and electrical equipment was limited in capabilities, and steel equipment rusted rapidly in

13716-655: The southernmost tip of South America via the Drake Passage , the Strait of Magellan or the Beagle Channel . It is one of the largest and most difficult engineering projects ever undertaken. Colombia , France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and

13843-421: The subsequent appearance of permanent human settlements allowed for the multiple and overlapping beginnings of civilizations in South America. One of the earliest known South American civilizations was Caral–Supe , on the central Peruvian coast. Though a pre-ceramic culture, the monumental architecture of Caral–Supe created one of the first cities of the world, generally dated to around 3500 BC, at Huaricanga in

13970-463: The subsistence economy, and natives were often captured by expeditions. The importation of African slaves began midway through the 16th century, but the enslavement of indigenous peoples continued well into the 17th and 18th centuries. The Atlantic slave trade brought enslaved Africans primarily to South American colonies, beginning with the Portuguese since 1502. The main destinations of this phase were

14097-406: The then-current president they were popularly known as The Roosevelt Medal. A total of 7189 were ultimately issued, with a few people receiving as many as four bars. Certificates are available today. In 1905, a US engineering panel was commissioned to review the canal design, which had not been finalized. In January 1906 the panel, in a majority of eight to five, recommended to President Roosevelt

14224-545: The thousands of incoming workers. Stevens began the recruitment effort to entice thousands of workers from the United States and other areas to come to the Canal Zone to work. Workers from the Caribbean—called " Afro-Panamanians "—came in large numbers and many settled permanently. Stevens tried to provide accommodation in which the workers could work and live in reasonable safety and comfort. He also re-established and enlarged

14351-588: The water from the lake. Gatun Lake would connect to the Pacific through the mountains at the Gaillard (Culebra) Cut. Unlike Godin de Lépinay with the Congrès International d'Etudes du Canal Interocéanique, Stevens successfully convinced Roosevelt of the necessity and feasibility of this alternative scheme. The construction of a canal with locks required the excavation of more than 17 million cu yd (13 million m ) of material over and above

14478-568: The western European architectural style to the continent, and helped to improve infrastructures like bridges, roads, and the sewer system of the cities they discovered or conquered. They also significantly increased economic and trade relations, not just between the old and new world but between the different South American regions and peoples. Finally, with the expansion of the Portuguese and Spanish languages, many cultures that were previously separated became united through that of Latin American. Guyana

14605-496: The work of Cuban epidemiologist, Carlos Finlay and American pathologist, Walter Reed . Investment was made in extensive sanitation projects, including city water systems, fumigation of buildings, spraying of insect-breeding areas with oil and larvicide, installation of mosquito netting and window screens, and elimination of stagnant water. Despite opposition from the commission (one member said his ideas were barmy), Gorgas persisted, and when Stevens arrived, he threw his weight behind

14732-464: Was Chile in 1823, Uruguay in 1830, Bolivia in 1831, Guyana in 1833, Colombia and Ecuador in 1851, Argentina in 1853, Peru and Venezuela in 1854, Suriname in 1863, Paraguay in 1869, and in 1888 Brazil was the last South American nation and the last country in western world to abolish slavery. The European Peninsular War (1807–14), a theater of the Napoleonic Wars , changed the political situation of

14859-455: Was US Army Major George Washington Goethals of the US Army Corps of Engineers . Soon to be promoted to lieutenant colonel and later to general, he was a strong, West Point -trained leader and civil engineer with experience in canals (unlike Stevens). Goethals directed the work in Panama to a successful conclusion in 1914, two years ahead of the target date of 10 June 1916. Goethals divided

14986-614: Was a useful form of agriculture. The Mapuche in Central and Southern Chile resisted the European and Chilean settlers, waging the Arauco War for more than 300 years. In 1494, Portugal and Spain, the two great maritime European powers of that time, on the expectation of new lands being discovered in the west, signed the Treaty of Tordesillas , by which they agreed, with the support of the Pope, that all

15113-534: Was able to raise considerable funds in France as a result of the huge profits generated by his successful construction of the Suez Canal . Although the Panama Canal needed to be only 40 percent as long as the Suez Canal, it was much more of an engineering challenge because of the combination of tropical rain forests, debilitating climate, the need for canal locks, and the lack of any ancient route to follow. Lesseps wanted

15240-495: Was carried out on the new approach channels, but the project was canceled after World War II. After World War II, US control of the canal and the Canal Zone surrounding it became contentious; relations between Panama and the United States became increasingly tense. Many Panamanians felt that the Zone rightfully belonged to Panama; student protests were met by the fencing-in of the zone and an increased military presence there. Demands for

15367-536: Was created to take over the project. A minimal workforce of a few thousand people was employed primarily to comply with the terms of the Colombian Panama Canal concession, to run the Panama Railroad , and to maintain the existing excavation and equipment in salable condition. The company sought a buyer for these assets, with an asking price of US$ 109,000,000. In the meantime, they continued with enough activity to maintain their franchise. Phillipe Bunau-Varilla ,

15494-472: Was given control of the Panama Canal Zone, over which the United States exercised sovereignty. The commission reported directly to Secretary of War William Howard Taft and was directed to avoid the inefficiency and corruption that had plagued the French 15 years earlier. On 6 May 1904, President Theodore Roosevelt appointed John Findley Wallace , formerly chief engineer and finally general manager of

15621-549: Was initially colonized by the Dutch before coming under British control , though there was a brief period during the Napoleonic Wars when it was occupied by the French . The region was initially partitioned between the Dutch, French and British before fully coming under the control of Britain. Suriname was first explored by the Spanish in the 16th century and then settled by the English in

15748-572: Was similarly responsible for the Pacific 3-mile (4.8 km) breakwater in Panama Bay , the approach channel to the locks, and the Miraflores and Pedro Miguel locks and their associated dams and reservoirs. The Central Division, under Major David du Bose Gaillard of the United States Army Corps of Engineers , was assigned one of the most difficult parts: excavating the Culebra Cut through

15875-501: Was summoned to Washington; he declared a sea-level approach to be "an entirely untenable proposition". He argued in favor of a canal using a lock system to raise and lower ships from a large reservoir 85 ft (26 m) above sea level. This would create both the largest dam (Gatun Dam) and the largest human-made lake (Gatun Lake) in the world at that time. The water to refill the locks would be taken from Gatun Lake by opening and closing enormous gates and valves and letting gravity propel

16002-415: Was the first self-propelled vessel to transit the canal from ocean to ocean. This vessel crossed the canal from the Atlantic in stages during construction, finally reaching the Pacific on 7 January 1914. SS Cristobal (a cargo and passenger ship built by Maryland Steel , and launched in 1902 as SS Tremont ) on 3 August 1914, was the first ship to transit the canal from ocean to ocean. The construction of

16129-434: Was won by the firm Hutchison Whampoa , a Hong Kong–based shipping interest owned by Li Ka-shing . While globally the Atlantic Ocean is east of the isthmus and the Pacific is west, the general direction of the canal passage from the Atlantic to the Pacific is from northwest to southeast, because of the shape of the isthmus at the point the canal occupies.
