From the 1930s, Bat Cave mine in Arizona was used for guano extraction, though it cost more to develop than it was worth. U.S. Guano Corporation bought the property in 1958 and invested 3.5 million dollars to make it operational; actual guano deposits in the cave were one percent of predicted and
1043-604: A deal to commercialize guano export among a merchant house in Liverpool , a group of French businessmen, and the Peruvian government. This agreement resulted in the abolition of all preexisting claims to Peruvian guano; thereafter, it was the exclusive resource of the State. By nationalizing its guano resources, the Peruvian government was able to collect royalties on its sale, becoming the country's largest source of revenue. Some of this income

The Incas of Cusco originally represented one of the small and relatively minor ethnic groups, the Quechuas . Gradually, as early as the thirteenth century, they began to expand and incorporate their neighbors. Inca expansion was slow until about the middle of
2533-636: A preemptive strike on Peru, resulting in its occupation of the Tarapacá , which included Peru's guano islands. With the Treaty of Ancón of 1884, the War of the Pacific ended. Bolivia ceded its entire coastline to Chile, which also gained half of Peru's guano income from the 1880s and its guano islands. The conflict ended with Chilean control over the most valuable nitrogen resources in the world. Chile's national treasury grew by 900% between 1879 and 1902 thanks to taxes coming from

It has been estimated that 70–95% of the total volume of Gomantong cave in Borneo is due to biological processes such as guano excretion, as the acidity of the guano weathers the rocky substrate. The presence of high densities of bats in a cave is predicted to cause the erosion of 1 metre (3 ft) of rock over 30,000 years. There are several references to guano in

11175-417: The Viceroyalty of Peru. Eventually, the viceroyalty would dissolve, as with much of the Spanish empire, when challenged by national independence movements at the beginning of the nineteenth century. These movements led to the formation of the majority of modern-day countries of South America in the territories that at one point or another had constituted the Viceroyalty of Peru. The conquest and colony brought
11324-512: The anti-corruption constitutional referendum movement. The COVID-19 pandemic resulted with Peru experiencing the highest death rate from COVID-19 in the world, exposing much of the inequality that persisted since the Fujimori administration and triggering an economic crisis that led to Vizcara's removal from the presidency by Congress . Widely seen as a coup by Congress, its head, the newly seated President Manuel Merino , faced protests across
11473-497: The arts. In his 1845 poem "Guanosong", German author Joseph Victor von Scheffel used a humorous verse to take a position in the popular polemic against Hegel 's Naturphilosophie . The poem starts with an allusion to Heinrich Heine 's Lorelei and may be sung to the same tune. The poem ends, however, with the blunt statement of a Swabian rapeseed farmer from Böblingen who praises the seagulls of Peru as providing better manure even than his fellow countryman Hegel. This refuted
11622-432: The authoritarian rule of Alberto Fujimori and Vladimiro Montesinos in the 1990s, with the former's political ideology of Fujimorism leaving a lasting imprint on the country's governance that continues to present day. The 2000s marked economic expansion and poverty reduction, but the subsequent decade revealed long-existing sociopolitical vulnerabilities , exacerbated by a political crisis instigated by Congress and
11771-608: The authorities – to a status equivalent to that of Spanish and established equal rights for natural children. Peru wished to free itself from any dependence and carried out a third-world foreign policy. The United States responded with commercial, economic and diplomatic pressure. In 1973 Peru seemed to triumph over the financial blockade imposed by Washington by negotiating a loan from the International Development Bank to finance its agricultural and mining development policy. The relations with Chile became very tense after
11920-813: The bats are not present, such as when migratory bats are gone for the season or when non-migratory bats are out foraging at night. Guano mining in Peru was at first done with black slaves. After Peru formally ended slavery , it sought another source of cheap labor. In the 1840s and 1850s, thousands of men were blackbirded (coerced or kidnapped) from the Pacific islands and southern China. Thousands of coolies from South China worked as "virtual slaves" mining guano. By 1852, Chinese laborers comprised two-thirds of Peru's guano miners; others who mined guano included convicts and forced laborers paying off debts . Chinese laborers agreed to work for eight years in exchange for passage from China, though many were misled that they were headed to California 's gold mines. Conditions on
12069-466: The birds with death. The guanay cormorant is historically the most abundant and important producer of guano. Other important guano-producing bird species off the coast of Peru are the Peruvian pelican and the Peruvian booby . The earliest European records noting the use of guano as fertilizer date back to 1548. Although the first shipments of guano reached Spain as early as 1700, it did not become
12218-502: The bombings of Tarata and Frecuencia Latina by Sendero Luminoso. Fujimori would also broaden the definition of terrorism in an effort to criminalize as many actions possible to persecute left-wing political opponents. Using the terruqueo , a fearmongering tactic that was used to accuse opponents of terrorism, Fujimori established a cult of personality by portraying himself as a hero and made left-wing ideologies an eternal enemy in Peru. Those incidents subsequently came to symbolize
12367-496: The boundary between those two countries. In a military coup on 29 October 1948, General Manuel A. Odría became president. Odría's presidency was known as the Ochenio . He came down hard on APRA, momentarily pleasing the oligarchy and all others on the right, but followed a populist course that won him great favor with the poor and lower classes. A thriving economy allowed him to indulge in expensive but crowd-pleasing social policies. At
12516-869: The cave as a roost, as happened when Robertson Cave in Australia had a hole opened in its ceiling for guano harvesting. Guano harvesting may also introduce artificial light into caves; one cave in the U.S. state of New Mexico was abandoned by its bat colony after the installation of electric lights. In addition to harming bats by necessitating they find another roost, guano harvesting techniques can ultimately harm human livelihood as well. Harming or killing bats means that less guano will be produced, resulting in unsustainable harvesting practices. In contrast, sustainable harvesting practices do not negatively impact bat colonies nor other cave fauna. The International Union for Conservation of Nature 's (IUCN) 2014 recommendations for sustainable guano harvesting include extracting guano when
12665-644: The church came to play an important role in the acculturation of the Natives, drawing them into the cultural orbit of the Spanish settlers. By the 18th century, declining silver production and economic diversification greatly diminished royal income. In response, the Crown enacted the Bourbon Reforms , a series of edicts that increased taxes and partitioned the Viceroyalty . The new laws provoked Túpac Amaru II's rebellion and other revolts, all of which were suppressed. As
12814-570: The coast of Namibia , and surrounding islands to Great Britain. Guano pirating took off in other regions as well, causing prices to plummet and more consumers to try it. The biggest markets for guano from 1840–1879 were in Great Britain, the Low Countries , Germany, and the United States. By the late 1860s, it became apparent that Peru's most productive guano site, the Chincha Islands ,
12963-448: The command of Gregorio Escobedo. Because Peru was the stronghold of the Spanish government in South America, San Martín's strategy to liberate Peru was to use diplomacy. He sent representatives to Lima urging the Viceroy that Peru be granted independence, however, all negotiations proved unsuccessful. The Viceroy of Peru, Joaquín de la Pazuela named José de la Serna commander-in-chief of
13112-407: The contemporary writer Inca Garcilaso de la Vega , son of an Inca princess and a conquistador. He said the name Birú was that of a common Amerindian who was happened upon by the crew of a ship on an exploratory mission for governor Pedro Arias Dávila and went on to relate more instances of misunderstandings due to the lack of a common language. The Spanish crown gave the name legal status with
13261-593: The contract they received in their own language lacked key amendments that the English version had. Because of this, the Hawaiian language contract was often missing key information, such as the departure date, the length of the contract, and the name of the company for which they would be working. When they arrived at their destination to begin mining, they learned that both contracts were largely meaningless in terms of work conditions. Instead, their overseer (commonly referred to as
13410-448: The country in the 1570s with gold and silver mining as its main economic activity and Amerindian forced labor as its primary workforce. With the discovery of the great silver and gold lodes at Potosí (present-day Bolivia) and Huancavelica , the viceroyalty flourished as an important provider of mineral resources. Peruvian bullion provided revenue for the Spanish Crown and fueled a complex trade network that extended as far as Europe and
13559-495: The country may be derived from Birú , the name of a local ruler who lived near the Bay of San Miguel , Panama City, in the early 16th century. Spanish conquistadors , who arrived in 1522, believed this was the southernmost part of the New World . When Francisco Pizarro invaded the regions farther south, they came to be designated Birú or Perú . An alternative history is provided by
13708-579: The country, and after five days, Merino resigned from the presidency. Merino was replaced by President Francisco Sagasti , who led a provisional, centrist government, and enforced many of Vizcarra's former policies. Elections were held on 11 April 2021, and Pedro Castillo of the Free Peru party won the first round, followed closely by Keiko Fujimori, with right-wing parties allied with Fujimori maintaining positions in Congress. On 28 July 2021, Pedro Castillo
13857-456: The country. After the country experienced chronic inflation , the Peruvian sol was replaced by the inti in mid-1985, which itself was replaced by the nuevo sol in July 1991 (the new sol had a cumulative value of one billion old soles). At the end of the 1980s, the per capita annual income of Peruvians fell to $ 720 (below the level of 1960) and Peru's GDP dropped 20%, with national reserves running
14006-773: The coup d'état of the general Pinochet . General Edgardo Mercado Jarrin (Prime Minister and Commander-in-Chief of the Army) and Admiral Guillermo Faura Gaig (Minister of the Navy) both escaped assassination attempts within weeks of each other. In 1975 General Francisco Morales Bermúdez Cerruti seized power and broke with the policies of his predecessor. His regime occasionally participated in Operation Condor in collaboration with other American military dictatorships. President Alan García 's economic policies distanced Peru from international markets further, resulting in lower foreign investment in
14155-597: The development of the Haber–Bosch process for extracting nitrogen from the atmosphere. Seabird guano is the fecal excrement from marine birds and has an organic matter content greater than 40%, and is a source of nitrogen (N) and available phosphate (P 2 O 5 ). Unlike most mammals, birds do not excrete urea , but uric acid , so that the amount of nitrogen per volume is much higher than in other animal excrement. Seabird guano contains plant nutrients including nitrogen , phosphorus , calcium and potassium . Bat guano
14304-855: The dominant energy resource of a cave. Many cave species depend on bat guano for sustenance, directly or indirectly. Because cave-roosting bats are often highly colonial , they can deposit substantial quantities of nutrients into caves. The largest colony of bats in the world at Bracken Cave (about 20 million individuals) deposit 50,000 kg (110,000 lb) of guano into the cave every year. Even smaller colonies have relatively large impacts, with one colony of 3,000 gray bats annually depositing 9 kg (20 lb) of guano into their cave. Invertebrates inhabit guano piles, including fly larvae , nematodes , springtails , beetles , mites , pseudoscorpions , thrips , silverfish , moths , harvestmen , spiders , isopods , millipedes , centipedes , and barklice . The invertebrate communities associated with
14453-500: The empire was Quechua , although hundreds of local languages and dialects were spoken. The Inca referred to their empire as Tawantinsuyu which can be translated as "The Four Regions" or "The Four United Provinces." Many local forms of worship persisted in the empire, most of them concerning local sacred Huacas , but the Inca leadership encouraged the worship of Inti , the sun god and imposed its sovereignty above other cults such as that of Pachamama . The Incas considered their King,
14602-461: The fifteenth century, when the pace of conquest began to accelerate, particularly under the rule of the emperor Pachacuti . Under his rule and that of his son, Topa Inca Yupanqui , the Incas came to control most of the Andean region, with a population of 9 to 16 million inhabitants under their rule. Pachacuti also promulgated a comprehensive code of laws to govern his far-flung empire, while consolidating his absolute temporal and spiritual authority as
14751-412: The first parliament was assembled. The newly founded Peruvian Congress named Bolívar dictator of Peru, giving him the power to organize the military. With the help of Antonio José de Sucre , they defeated the larger Spanish army in the Battle of Junín on 6 August 1824 and the decisive Battle of Ayacucho on 9 December of the same year, consolidating the independence of Peru and Upper Peru. Upper Peru
14900-605: The following three decades. A final peace treaty in 1929, signed between Peru and Chile called the Treaty of Lima , returned Tacna to Peru. Between 1932 and 1933, Peru was engulfed in a year-long war with Colombia over a territorial dispute involving the Amazonas Department and its capital Leticia . In 1941 Peru and Ecuador fought the Ecuadorian–Peruvian War , after which the Rio Protocol sought to formalize
15049-499: The fray and since then became Peru's greatest hero. Almost five years of war ended with the loss of the department of Tarapacá and the provinces of Tacna and Arica , in the Atacama region. Francisco Bolognesi and Miguel Grau are both renowned heros of the war. Originally Chile committed to a referendum for the cities of Arica and Tacna to be held years later, to self determine their national affiliation. However, Chile refused to apply
15198-420: The guano depends on the bat species' feeding guild : frugivorous bat guano has the greatest invertebrate diversity. Some invertebrates feed directly on the guano, while others consume the fungi that use it as a growth medium. Predators such as spiders depend on guano to support their prey base. Vertebrates consume guano as well, including the bullhead catfish and larvae of the grotto salamander . Bat guano
15347-429: The guano islands were very poor, commonly resulting in floggings , unrest, and suicide . Workers experienced lung damage by inhaling guano dust, were buried alive by falling piles of guano, and risked falling into the ocean. After visiting the guano islands, U.S. politician George Washington Peck wrote: I observed Coolies shoveling and wheeling as if for dear life and yet their backs were covered with great welts...It
15496-402: The guano. The use of excavation machinery is not only impractical due to the terrain but also prohibited because it would frighten the seabirds. The guano is then placed in sacks and carried to sieves , where impurities are removed. Similarly, harvesting bat guano in caves was and is manual. In Puerto Rico , cave entrances were enlarged to facilitate access and extraction. Guano was freed from
15645-520: The help of Bolivia , Chile and Ecuador , sent a declaration of war on Spain. After the battle of Callao on May 2, 1866, the Spanish Navy withdrew from Peru. The government of José Balta was lavish in infrastructure works (construction of the Central Railway ) although the first signs of excess government spending were already perceived. By the 1870s the guano resources had been depleted, the country
15794-430: The highlands near Cuzco. In the early 19th century, while most South American nations were swept by wars of independence , Peru remained a royalist stronghold. As the elite vacillated between emancipation and loyalty to the Spanish monarchy, independence was achieved only after the occupation by military campaigns of José de San Martín and Simón Bolívar . The economic crises, the loss of power of Spain in Europe,
15943-448: The immunocompromised avoid exploring caves or old buildings, cleaning chicken coops, or disturbing soil where guano is present. Rabies , which can affect humans who have been bitten by infected mammals including bats, cannot be transmitted through bat guano. A 2011 study of bat guano viromes in the U.S. states of Texas and California recovered no viruses that are pathogenic to humans, nor any close relatives of pathogenic viruses. It
16092-465: The labor population to expand the workforce. The expansion of a colonial administrative apparatus and bureaucracy paralleled the economic reorganization. With the conquest started the spread of Christianity in South America; most people were forcefully converted to Catholicism , with Spanish clerics believing like Puritan divines of English colonies later that the Native Peoples "had been corrupted by
16241-524: The late 1800s, approximately 53 million seabirds lived on the twenty-two islands. As of 2011, only 4.2 million seabirds lived there. After realizing the depletion of guano in the Guano Age, the Peruvian government recognized that it needed to conserve the seabirds. In 1906, American zoologist Robert Ervin Coker was hired by the Peruvian government to create management plans for its marine species, including
16390-526: The latest farming experiments, including guano. In an effort to impress the upper class around him and disguise his low-class origins, Jorrocks references guano in conversation at every chance he can. At one point, he exclaims, "Guano!" along with two other varieties of fertilizer, to which the Duke replies, "I see you understand it all!" Guano is also the namesake for one of the nucleobases in RNA and DNA : guanine ,
16539-473: The loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria , fungi , invertebrates , and vertebrates . The loss of bats from a cave can result in the extinction of species that rely on their guano. Unsustainable harvesting of bat guano may cause bats to abandon their roost. Demand for guano rapidly declined after 1910 with
16688-410: The loyalist army to protect Lima from the threatened invasion by San Martín. On 29 January, de la Serna organized a coup against de la Pazuela, which was recognized by Spain and he was named Viceroy of Peru. This internal power struggle contributed to the success of the liberating army. To avoid a military confrontation, San Martín met the newly appointed viceroy, José de la Serna, and proposed to create
16837-526: The military officers involved in Plan Verde to abide by the military's demands prior to Fujimori's inauguration. Fujimori would go on to adopt many of the policies outlined in Plan Verde, which led to a precitious drop in infliation from 7,650% at the start of 1990 to 139% in 1991 and 57% in 1992. When Fujimori faced opposition to his reform efforts, he dissolved Congress, suspending the judiciary, arresting several opposition leaders and assuming full powers in
16986-542: The mine was abandoned in 1960. In Australia, the first documented claim on Naracoorte 's Bat Cave guano deposits was in 1867. Guano mining in the country remained a localized and small industry. In modern times, bat guano is used in low levels in developed countries . It remains an important resource in developing countries , particularly in Asia. Coring accumulations of bat guano can be useful in determining past climate conditions. The level of rainfall, for example, impacts
17135-420: The more outstanding Chimu and Moche . The Moche, who reached their apogee in the first millennium CE, were renowned for their irrigation system which fertilized their arid terrain, their sophisticated ceramic pottery, their lofty buildings, and clever metalwork. The Chimu were the great city builders of pre-Inca civilization; as a loose confederation of walled cities scattered along the coast of northern Peru,
17284-451: The mountain region, which covers almost a third of the country, rain is frequent in summer, and temperature and humidity diminish with altitude up to the frozen peaks of the Andes. The Peruvian Amazon , covering more than half of the total area of Peru, is characterized by heavy rainfall and high temperatures, except for its southernmost part, which has cold winters and seasonal rainfall. Because of its varied geography and climate, Peru has
17433-418: The naval campaign, the Peruvian navy repelled the Chilean attack until October 8, 1879, the day in which the naval combat of Angamos was fought, where the Chilean navy with its ships Cochrane, Blanco Encalada, Loa and Covadonga cornered the monitor Huáscar, the main ship of the Peruvian navy commanded by Admiral AP Miguel Grau, who died in the fray and since then became Peru's greatest hero. In 1879 Peru entered
17582-683: The newly acquired lands. The demand for guano led the United States to pass the Guano Islands Act in 1856, which gave U.S. citizens discovering a source of guano on an unclaimed island exclusive rights to the deposits. In 1857, the U.S. began annexing uninhabited islands in the Pacific and Caribbean, totaling nearly 100, though some islands claimed under the Act did not end up having guano mining operations established on them. Several of these islands are still officially U.S. territories. Conditions on annexed guano islands were poor for workers, resulting in
17731-442: The nitrate and guano territories of southern Peru and Bolivia. In the first stage of the war, the naval campaign, the Peruvian navy repelled the Chilean attack until October 8, 1879, the day in which the naval combat of Angamos was fought, where the Chilean navy with its ships Cochrane, Blanco Encalada, Loa and Covadonga cornered the monitor Huáscar , the main ship of the Peruvian navy, commanded by Admiral AP Miguel Grau, who died in
17880-466: The opposition-controlled legislature and create an "exceptional emergency government." In response, Congress quickly held an emergency session on the same day, during which it voted 101–6 (with 10 abstentions) to remove Castillo from office and replace him with Vice President Dina Boluarte . She became the country's first female president. Castillo was arrested after trying to flee to the Mexican embassy and
18029-536: The port of Paracas under the command of General José de San Martín and Thomas Cochrane , who was serving in the Chilean Navy. Immediately on 26 October, they took control of the town of Pisco . San Martín settled in Huacho on 12 November, where he established his headquarters while Cochrane sailed north and blockaded the port of Callao in Lima. At the same time in the north, Guayaquil was occupied by rebel forces under
18178-422: The relative frequency of nitrogen isotopes . In times of higher rainfall, N is more common. Bat guano also contains pollen , which can be used to identify prior plant assemblages. A layer of charcoal recovered from a guano core in the U.S. state of Alabama was seen as evidence that a Woodlands tribe inhabited the cave for some time, leaving charcoal via the fires they lit. Stable isotope analysis of bat guano
18327-656: The rising popularity of organic food in the twenty-first century, the demand for guano has started to rise again. In the U.S., bat guano was harvested from caves as early as the 1780s to manufacture gunpowder . During the American Civil War (1861–1865), the Union 's blockade of the southern Confederate States of America meant that the Confederacy resorted to mining guano from caves to produce saltpetre . One Confederate guano kiln in New Braunfels, Texas , had
18476-426: The rocky substrate by explosives. Then, it was shoveled into carts and removed from the cave. From there, the guano was taken to kilns to dry. The dried guano would then be loaded into sacks, ready for transport via ship. Today, bat guano is usually harvested in the developing world, using "strong backs and shovels". Peru's guano islands experienced severe ecological effects as a result of unsustainable mining. In
18625-492: The same time, however, civil rights were severely restricted and corruption was rampant throughout his regime. Odría was succeeded by Manuel Prado Ugarteche . However, widespread allegations of fraud prompted the Peruvian military to depose Prado and install a military junta, via a coup d'état led by Ricardo Pérez Godoy . Godoy ran a short transitional government and held new elections in 1963, which were won by Fernando Belaúnde Terry who assumed presidency until 1968. Belaúnde
18774-531: The seabirds, including keeping unauthorized visitors a mile away from guano islands at all times, eliminating all the birds' natural predators, armed patrols of the islands, and decreasing the frequency of harvest on each island to once every three to four years. In 2009, these conservation efforts culminated in the establishment of the Guano Islands, Isles, and Capes National Reserve System , which consists of twenty-two islands and eleven capes . This Reserve System
18923-496: The seabirds. Specifically, he made five recommendations: Despite these policies, the seabird population continued to decline, which was exacerbated by the 1911 El Niño–Southern Oscillation . In 1913, Scottish ornithologist Henry Ogg Forbes authored a report on behalf of the Peruvian Corporation focusing on how human actions harmed the birds and subsequent guano production. Forbes suggested additional policies to conserve
19072-423: The split of the viceroyalty and the creation of new viceroyalties of New Granada and Rio de la Plata at the expense of the territories that formed the Viceroyalty of Peru ; this reduced the power, prominence and importance of Lima as the viceroyal capital and shifted the lucrative Andean trade to Buenos Aires and Bogotá , while the fall of the mining and textile production accelerated the progressive decay of
19221-457: The tree-line known as puna is home to bushes, cactus , drought-resistant plants such as ichu , and the largest species of bromeliad – the spectacular Puya raimondii . Guano Guano (Spanish from Quechua : wanu ) is the accumulated excrement of seabirds or bats . Guano is a highly effective fertilizer due to the high content of nitrogen , phosphate , and potassium , all key nutrients essential for plant growth. Guano
19370-620: The viceroyalty as well as expeditions towards the Amazon Basin as in the case of Spanish efforts to quell Amerindian resistance. The last Inca resistance was suppressed when the Spaniards annihilated the Neo-Inca State in Vilcabamba in 1572. The Indigenous population dramatically collapsed overwhelmingly due to epidemic diseases introduced by the Spanish as well as exploitation and socio-economic change. Viceroy Francisco de Toledo reorganized
19519-565: The war were followed by a period of stability under the Civilista Party , which lasted until the onset of the authoritarian regime of Augusto B. Leguía . The Great Depression caused the downfall of Leguía, renewed political turmoil, and the emergence of the American Popular Revolutionary Alliance (APRA). The rivalry between this organization and a coalition of the elite and the military defined Peruvian politics for
19668-474: The widespread Enlightenment belief that nature in the New World was inferior to the Old World . The poem has been translated by, among others, Charles Godfrey Leland . English author Robert Smith Surtees parodied the obsession of wealthy landowners with the "religion of progress" in 1843. In one of his works featuring the character John Jorrocks, Surtees has the character develop an obsession with trying all
19817-559: Was also used to support that the climate of the Grand Canyon was cooler and wetter during the Pleistocene epoch than it is now in the Holocene . Additionally, the climatic conditions were more variable in the past. Mining seabird guano from Peruvian islands has remained largely the same since the industry began, relying on manual labor . First, picks, brooms, and shovels are used to loosen
19966-420: Was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern input-intensive farming . The demand for guano spurred the human colonization of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and
20115-423: Was charged with the crime of rebellion. The Boluarte government proved unpopular as she allied herself with the right-wing Congress and the military, betraying her constituents. This resentment led to the 2022–2023 Peruvian political protests , which sought the removal of Boluarte and Congress, immediate general elections and the writing of a new constitution. Authorities responded to the protests violently, with
20264-495: Was dogged by insurgent groups, most notably Shining Path, which carried out attacks across the country throughout the 1980s and 1990s. Fujimori cracked down on the insurgents and was successful in largely quelling them by the late 1990s, but the fight was marred by atrocities committed by both the Peruvian security forces and the insurgents: the Barrios Altos massacre and La Cantuta massacre by Government paramilitary groups, and
20413-412: Was exhausting and punishments were brutal. Laborers were frequently placed in stocks or tied up and dangled in the air. A labor revolt ensued, where the workers attacked their overseers with stones, axes, and even dynamite, killing five overseers. Although the process for mining guano is mostly the same today, worker conditions have improved. As of 2018, guano miners in Peru made US$ 750 per month, which
20562-663: Was forged during this period, as Bolivarian projects for a Latin American Confederation floundered and a union with Bolivia proved ephemeral. Simón Bolívar launched his campaign from the north, liberating the Viceroyalty of New Granada in the Battles of Carabobo in 1821 and Pichincha a year later. In July 1822, Bolívar and San Martín gathered in the Guayaquil Conference . Bolívar was left in charge of fully liberating Peru while San Martín retired from politics after
20711-543: Was heavily indebted, and political in-fighting was again on the rise. By 1859, some 41,000 Peruvians had died in the constant civil wars that shook the country since 1829. Thanks to the money from the sale of guano, Peru began to modernize with different public works such as railways; the civil and military bureaucracy grew; The indigenous people stopped paying tribute and the slaves achieved their freedom; The migration policy of Germans, Austrians, Irish and Italians began. On April 5, 1879, Chile declared war on Peru, unleashing
20860-519: Was later established as Bolivia. During the early years of the Republic, endemic struggles for power between military leaders caused political instability. Once independence was proclaimed, San Martín assumed military-political command of the free departments of Peru, under the title of Protector, according to a decree given on August 3, 1821. 74 The works of the Protectorate contributed to the creation of
21009-421: Was nearing depletion. This caused guano mining to shift to other islands north and south of the Chincha Islands. Despite this near exhaustion, Peru achieved its greatest ever export of guano in 1870 at more than 700,000 tonnes (770,000 short tons). Concern of exhaustion was ameliorated by the discovery of a new Peruvian resource: sodium nitrate , also called Chile saltpetre. After 1870, the use of Peruvian guano as
21158-564: Was probably more of a religious than a political phenomenon, with their religious center in Chavín de Huantar . After the decline of the Chavin culture around the beginning of the 1st century CE, a series of localized and specialized cultures rose and fell, both on the coast and in the highlands, during the next thousand years. On the coast, these included the civilizations of the Paracas , Nazca , Wari , and
21307-479: Was recognized for his commitment to the democratic process. On 3 October 1968 another coup d'état led by a group of officers led by General Juan Velasco Alvarado brought the army to power with the aim of applying a doctrine of "social progress and integral development", nationalist and reformist, influenced by the CEPAL theses on dependence and underdevelopment. Six days after the golpe, Velasco proceeded to nationalize
21456-434: Was sworn in as the new president of Peru after a narrow win in a tightly contested run-off election. That same year, Peru celebrated the bicentenary of independence . Castillo faced multiple impeachment votes during his presidency from the right-wing controlled Congress and on 7 December 2022, just hours before Congress was set to begin a third impeachment effort , Castillo tried to prevent this by attempting to dissolve
21605-432: Was the first marine protected area in South America, encompassing 140,833 hectares (348,010 acres). Unlike bird guano which is deposited on the surface of islands, bat guano can be deep within caves. Cave structure is often altered via explosives or excavation to facilitate extraction of the guano, which changes the cave's microclimate . Bats are sensitive to cave microclimate, and such changes can cause them to abandon
