Figures vary on personnel, but as of are approximately 223,000 armed forces personnel (160,000 Army; 8,000 Air Force; 55,000 Navy, including about 20,000 Marines); approximately 100,000 National Guard (2021). Government expenditures on the military are a small proportion of GDP: 0.7% of GDP (2021 est.), 0.6% of GDP (2020). The Mexican Armed Forces maintain significant infrastructure, including facilities for
10360-475: The PAN was declared the winner, with a very narrow margin (0.58%) over leftist politician Andrés Manuel López Obrador of the Party of the Democratic Revolution (PRD). López Obrador, however, contested the election and pledged to create an "alternative government". After twelve years, in the 2012 presidential election , the PRI again won the presidency with the election of Enrique Peña Nieto . However, he won with
10500-450: The PRI and challenged Salinas in the 1988 elections. In 1988 there was massive electoral fraud , with results showing that Salinas had won the election by the narrowest percentage ever. There were massive protests in Mexico City over the stolen election. Salinas took the oath of office on 1 December 1988. In 1990 the PRI was famously described by Mario Vargas Llosa as the "perfect dictatorship", but by then there had been major challenges to
10640-517: The PRI's hegemony. Salinas embarked on a program of neoliberal reforms that fixed the exchange rate of the peso, controlled inflation, opened Mexico to foreign investment, and began talks with the U.S. and Canada to join their free-trade agreement , which culminated in the North American Free Trade Agreement (NAFTA) on 1 January 1994; the same day, the Zapatista Army of National Liberation (EZLN) in Chiapas began armed peasant rebellion against
10780-467: The U.S. entered World War I. Although often viewed as an internal conflict, the revolution had significant international elements: Germany attempted to get Mexico to side with it, sending a coded telegram in 1917 to incite war between the U.S. and Mexico, with Mexico to regain the territory it lost in the Mexican-American War but Mexico remained neutral in the conflict. In 1916, the winners of
10920-399: The United States and Canada indicate that the ruby-throated hummingbird numbers are around 34 million, rufous hummingbirds are around 19 million, black-chinned , Anna's , and broad-tailed hummingbirds are about 8 million each, calliopes at 4 million, and Costa's and Allen's hummingbirds are around 2 million each. Several species exist only in the thousands or hundreds. According to
11060-428: The United States and Canada, several have changed their range of distribution, while others showed declines in numbers since the 1970s, including in 2023 with dozens of hummingbird species in decline. As of the 21st century, rufous, Costa's, calliope, broad-tailed, and Allen's hummingbirds are in significant decline, some losing as much as 67% of their numbers since 1970 at nearly double the rate of population loss over
11200-524: The army for a short period were incorporated as sectors of the single party that dominated Mexican politics from its founding in 1929. Obregón instigated land reform and strengthened the power of organized labor. He gained recognition from the United States and took steps to settle claims with companies and individuals that lost property during the Revolution. He imposed his fellow former Sonoran revolutionary general, Calles, as his successor, prompting an unsuccessful military revolt. As president, Calles provoked
11340-415: The arts and sciences. Díaz ruled with a group of advisors that became known as the científicos ('scientists'). The most influential científico was Secretary of Finance José Yves Limantour . The Porfirian regime was influenced by positivism . They rejected theology and idealism in favor of scientific methods being applied towards national development. An integral aspect of the liberal project
11480-460: The battlefield, Lerdo fled from office into exile. After the turmoil in Mexico from 1810 to 1876, the 35-year rule of Liberal General Porfirio Díaz (r.1876–1911) allowed Mexico to rapidly modernize in a period characterized as one of " order and progress ". The Porfiriato was characterized by economic stability and growth, significant foreign investment and influence, an expansion of the railroad network and telecommunications, and investments in
11620-484: The battlefield, but Conservatives sought another solution to gain power via foreign intervention by the French, asking Emperor Napoleon III to place a European monarch as head of state in Mexico. The French Army defeated the Mexican Army and placed Maximilian Habsburg on the newly established throne of Mexico, supported by Mexican Conservatives and propped up by the French Army. The Liberal Republic under Benito Juárez
11760-669: The bee hummingbird to more successfully compete for flower foraging against insects. Many plants pollinated by hummingbirds produce flowers in shades of red, orange, and bright pink, although the birds take nectar from flowers of other colors. Hummingbirds can see wavelengths into the near- ultraviolet , but hummingbird-pollinated flowers do not reflect these wavelengths as many insect-pollinated flowers do. This narrow color spectrum may render hummingbird-pollinated flowers relatively inconspicuous to most insects, thereby reducing nectar robbing . Hummingbird-pollinated flowers also produce relatively weak nectar (averaging 25% sugars) containing
11900-595: The capabilities to manufacture nuclear weapons, but abandoned this possibility with the Treaty of Tlatelolco in 1968 and pledged to use its nuclear technology only for peaceful purposes. Mexico signed the UN treaty on the Prohibition of Nuclear Weapons . Historically, Mexico has remained neutral in international conflicts, with the exception of World War II . However, in recent years some political parties have proposed an amendment of
12040-604: The colonial era. Notable Amerindian revolts in sporadically populated northern New Spain include the Chichimeca War (1576–1606), Tepehuán Revolt (1616–1620), and the Pueblo Revolt (1680), the Tzeltal Rebellion of 1712 was a regional Maya revolt. Most rebellions were small-scale and local, posing no major threat to the ruling elites. To protect Mexico from the attacks of English, French, and Dutch pirates and protect
12180-404: The colony of New Spain centered in the former capital, Tenochtitlan (now Mexico City ). The Mexican War of Independence in the early 19th century was followed by political and socioeconomic upheaval. The Mexican–American War resulted in significant territorial losses in 1848. Liberal reforms introduced in the Constitution of 1857 prompted domestic conflict, French intervention , and
12320-739: The comparably small Ecuador has about 130 species. The family Trochilidae was introduced in 1825 by Irish zoologist Nicholas Aylward Vigors with Trochilus as the type genus . In traditional taxonomy , hummingbirds are placed in the order Apodiformes , which also contains the swifts , but some taxonomists have separated them into their own order, the Trochiliformes. Hummingbirds' wing bones are hollow and fragile, making fossilization difficult and leaving their evolutionary history poorly documented. Though scientists theorize that hummingbirds originated in South America, where species diversity
12460-668: The construction of large ceremonial centers. The earliest complex civilization in Mexico was the Olmec culture, which flourished on the Gulf Coast from around 1500 BC. Olmec cultural traits diffused through Mexico into other formative-era cultures in Chiapas, Oaxaca, and the Valley of Mexico. In the subsequent pre-classical period , the Maya and Zapotec civilizations developed complex centers at Calakmul and Monte Albán , respectively. During this period
12600-415: The country; temperate humid and sub-humid being found mostly on pastures at an elevation of 1,800 meters and higher in central Mexico and cold climate usually found at an elevation of 3,500 meters and beyond. Most of the country's territory has a temperate to dry climate. Areas south of the Tropic of Cancer with elevations up to 1,000 m (3,281 ft) (the southern parts of both coastal plains as well as
12740-479: The de facto head of Mexico, and the U.S. recognized his government while Zapata's forces in the south reverted to guerrilla warfare. After Pancho Villa was defeated by revolutionary forces in 1915, he led an incursion raid into Columbus, New Mexico , prompting the U.S. to send 10,000 troops led by General John J. Pershing in an unsuccessful attempt to capture Villa. Carranza pushed back against U.S. troops being in northern Mexico. The expeditionary forces withdrew as
12880-563: The design, research, and testing of weapons, vehicles, aircraft, naval vessels, defense systems and electronics; military industry manufacturing centers for building such systems, and advanced naval dockyards that build heavy military vessels and advanced missile technologies. Since the 1990s, when the military escalated its role in the war on drugs , increasing importance has been placed on acquiring airborne surveillance platforms, aircraft, helicopters , digital war-fighting technologies, urban warfare equipment and rapid troop transport. Mexico has
13020-627: The discovery of vast silver deposits in northern Mexico. The Kingdom of New Spain was created from the remnants of the Aztec empire. The two pillars of Spanish rule were the State and the Roman Catholic Church, both under the authority of the Spanish crown. In 1493 the pope had granted sweeping powers to the Spanish monarchy for its overseas empire, with the proviso that the crown spread Christianity in its new realms. In 1524, King Charles I created
13160-421: The earliest species of hummingbird occurred in the early Oligocene ( Rupelian about 34–28 million years ago) of Europe, belonging to the genus Eurotrochilus, having similar morphology to modern hummingbirds. A phylogenetic tree unequivocally indicates that modern hummingbirds originated in South America, with the last common ancestor of all living hummingbirds living around 22 million years ago. A map of
13300-658: The end of the post-Classic period, the Aztecs (or Mexica ) established dominance, establishing a political and economic empire based in the city of Tenochtitlan (modern Mexico City ), extending from central Mexico to the border with Guatemala. Although the Spanish Empire had established colonies in the Caribbean starting in 1493 the Spanish first learned of Mexico during the Juan de Grijalva expedition of 1518. The Spanish conquest of
13440-475: The establishment of an Empire , countered by the Republican resistance led by Benito Juárez . The rise of Porfirio Díaz 's dictatorship in the 19th century sparked the Mexican Revolution in 1910, which led to profound changes, such as the 1917 Constitution . Over the 20th century, Mexico experienced significant economic growth ; as well as issues of repression and electoral fraud . The late 20th century saw
13580-777: The extension of the Rocky Mountains from northern North America crossed the country from north to south and a fourth mountain range, the Sierra Madre del Sur , runs from Michoacán to Oaxaca . The Mexican territory is prone to volcanism . Mexico has nine distinct regions: Baja California , the Pacific Coastal Lowlands, the Mexican Plateau , the Sierra Madre Oriental , the Sierra Madre Occidental ,
13720-454: The federal government, which captured a few towns but brought world attention to the situation in Mexico. The armed conflict was short-lived and has continued as a non-violent opposition movement against neoliberalism and globalization . In 1994, following the assassination of the PRI's presidential candidate Luis Donaldo Colosio , Salinas was succeeded by victorious PRI candidate Ernesto Zedillo . Salinas left Zedillo's government to deal with
13860-537: The first minority or first-runner-up (one for each state and one for Mexico City), and 32 are elected by proportional representation from national closed party lists. The executive is the President of the United Mexican States , who is the head of state and government , as well as the commander-in-chief of the Mexican military forces. The President also appoints the Cabinet and other officers. The President
14000-596: The first true Mesoamerican writing systems were developed in the Epi-Olmec and Zapotec cultures. The Mesoamerican writing tradition reached its height in the Classic Maya Hieroglyphic script , the earliest written histories date from this era. The tradition of writing was important after the Spanish conquest in 1521, with indigenous scribes learning to write their languages in alphabetic letters, while also continuing to create pictorial texts. In Central Mexico,
14140-493: The formation of new species of hummingbirds and plants. Due to this exceptional evolutionary pattern, as many as 140 hummingbird species can coexist in a specific region, such as the Andes range . The hummingbird evolutionary tree shows that one key evolutionary factor appears to have been an altered taste receptor that enabled hummingbirds to seek nectar. Upon maturity, males of a particular species, Phaethornis longirostris,
14280-442: The height of the classic period saw the ascendancy of Teotihuacán , which formed a military and commercial empire. Teotihuacan, with a population of more than 150,000 people, had some of the largest pyramidal structures in the pre-Columbian Americas. After the collapse of Teotihuacán around 600 AD, competition ensued between several important political centers in central Mexico such as Xochicalco and Cholula . At this time, during
14420-456: The hermits are sister to the topazes , making the former definition of the Trochilinae not monophyletic . The hummingbirds form nine major clades : the topazes and jacobins , the hermits, the mangoes , the coquettes , the brilliants , the giant hummingbird ( Patagona gigas ), the mountaingems , the bees , and the emeralds . The topazes and jacobins combined have the oldest split with
14560-528: The highest elevations are found at the Trans-Mexican Volcanic Belt which crosses Mexico east to west: Pico de Orizaba (5,700 m or 18,701 ft), Popocatépetl (5,462 m or 17,920 ft) and Iztaccihuatl (5,286 m or 17,343 ft) and the Nevado de Toluca (4,577 m or 15,016 ft). Two mountain ranges known as Sierra Madre Oriental and Sierra Madre Occidental , which are
14700-455: The humming sound created by their beating wings , which flap at high frequencies audible to other birds and humans. They hover at rapid wing-flapping rates, which vary from around 12 beats per second in the largest species to 80 per second in small hummingbirds. Hummingbirds have the highest mass-specific metabolic rate of any homeothermic animal. To conserve energy when food is scarce and at night when not foraging, they can enter torpor ,
14840-464: The hummingbird family tree – reconstructed from analysis of 284 species – shows rapid diversification from 22 million years ago. Hummingbirds fall into nine main clades – the topazes , hermits , mangoes , brilliants , coquettes , the giant hummingbird, mountaingems , bees , and emeralds – defining their relationship to nectar -bearing flowering plants which attract hummingbirds into new geographic areas. Molecular phylogenetic studies of
14980-542: The hummingbirds have shown that the family is composed of nine major clades. When Edward Dickinson and James Van Remsen Jr. updated the Howard and Moore Complete Checklist of the Birds of the World for the 4th edition in 2013, they divided the hummingbirds into six subfamilies. Molecular phylogenetic studies determined the relationships between the major groups of hummingbirds. In
15120-607: The increase of inequality between urban and rural areas. The Green Revolution , a technological movement that led to a significant worldwide increase in crop production, began in the Yaqui Valley of Sonora in the middle of the 20th century. With robust economic growth, Mexico sought to showcase it to the world by hosting the 1968 Summer Olympics . The government poured huge resources into building new facilities, prompting political unrest among university students and others. Demonstrations in central Mexico City went on for weeks before
15260-431: The indigenous language of Nahuatl . Tequila , the distilled alcoholic drink made from cultivated agave cacti is a major industry. Because of its high biodiversity Mexico has also been a frequent site of bioprospecting by international research bodies. The first highly successful instance was the discovery in 1947 of the tuber " Barbasco " ( Dioscorea composita ) which has a high content of diosgenin , revolutionizing
15400-513: The mob. On 16 September 1810, secular priest Miguel Hidalgo y Costilla declared against "bad government" in the small town of Dolores , Guanajuato. This event, known as the Cry of Dolores ( Spanish : Grito de Dolores ) is commemorated each year, on 16 September, as Mexico's independence day. The upheaval in the Spanish Empire that resulted in the independence of most of its New World territories
15540-474: The north like Monterrey , Hermosillo , and Mexicali experience temperatures of 40 °C (104 °F) or more in summer. In the Sonoran Desert temperatures reach 50 °C (122 °F) or more. There are 7 major climate types in Mexico with warm sub-humid climate being coastal up to 900 meters found mostly in the southern region of Mexico; dry and desertic climates being found in the northern half of
15680-478: The planned opening of the games, with the government of Gustavo Díaz Ordaz cracking down. The culmination was the Tlatelolco Massacre , which killed around 300 protesters based on conservative estimates and perhaps as many as 800. Although the economy continued to flourish for some, social inequality remained a factor of discontent. PRI rule became increasingly authoritarian and at times oppressive in what
15820-537: The political spectrum. The coalition also won a majority in both the upper and lower Congress chambers. His success is attributed to the country's opposing political forces exhausting their chances as well as AMLO's adoption of a moderate discourse with a focus on reconciliation. The first confirmed case of COVID-19 in Mexico occurred on 28 February 2020. The COVID-19 vaccination in Mexico began in December 2020. Claudia Sheinbaum , López Obrador's political successor, won
15960-520: The politics for the next 25 years, often known as the "Age of Santa Anna", until his overthrow in 1855. Mexico also contended with indigenous groups that controlled the territory that Mexico claimed in the north. For example, the Comanche controlled a huge territory in sparsely populated central and northern Texas. Wanting to stabilize and develop that area — and as few people from central Mexico had chosen to resettle to this remote and hostile territory —
16100-489: The post-revolutionary period (1920–1946) was characterized by revolutionary generals serving as Presidents of Mexico , including Álvaro Obregón (1920–24), Plutarco Elías Calles (1924–28), Lázaro Cárdenas (1934–40), and Manuel Avila Camacho (1940–46). The post-revolutionary project of the Mexican government sought to bring order to the country, end military intervention in politics, and create organizations of interest groups. Workers, peasants, urban office workers, and even
16240-481: The presidency of Lázaro Cárdenas , who expelled Calles from the country and implemented many economic and social reforms. This included the Mexican oil expropriation in March 1938, which nationalized the U.S. and Anglo-Dutch oil company known as the Mexican Eagle Petroleum Company , which would result in the creation of the state-owned Pemex . Cárdenas's successor, Manuel Ávila Camacho (1940–1946)
16380-788: The previous 50 years. The ruby-throated hummingbird population – the most populous North American hummingbird – decreased by 17% over the early 21st century. Habitat loss, glass collisions, cat predation, pesticides , and possibly climate change affecting food availability, migration signals, and breeding are factors that may contribute to declining hummingbird numbers. By contrast, Anna's hummingbirds had large population growth at an accelerating rate since 2010, and expanded their range northward to reside year-round in cold winter climates. Some species of sunbirds — an Old World group restricted in distribution to Eurasia , Africa, and Australia — resemble hummingbirds in appearance and behavior, but are not related to hummingbirds, as their resemblance
16520-401: The production of synthetic hormones in the 1950s and 1960s and eventually leading to the invention of combined oral contraceptive pills . The United Mexican States are a federation whose government is representative , democratic, and republican based on a presidential system according to the 1917 Constitution . The Constitution establishes three levels of government: the federal Union,
16660-785: The rest of the hummingbirds. The hummingbird family has the third-greatest number of species of any bird family (after the tyrant flycatchers and the tanagers ). Fossil hummingbirds are known from the Pleistocene of Brazil and the Bahamas , but neither has yet been scientifically described, and fossils and subfossils of a few extant species are known. Until recently, older fossils had not been securely identifiable as those of hummingbirds. In 2004, Gerald Mayr identified two 30-million-year-old hummingbird fossils. The fossils of this primitive hummingbird species, named Eurotrochilus inexpectatus ("unexpected European hummingbird"), had been sitting in
16800-480: The roughly 25 million years between the primitive Eurotrochilus and the modern fossils. The astounding morphological adaptations , the decrease in size, and the dispersal to the Americas and extinction in Eurasia all occurred during this timespan. DNA–DNA hybridization results suggest that the main radiation of South American hummingbirds took place at least partly in the Miocene , some 12 to 13 million years ago, during
16940-974: The second fastest rate of deforestation in the world, second only to Brazil. It had a 2019 Forest Landscape Integrity Index mean score of 6.82/10, ranking it 63rd globally out of 172 countries. According to SGI there is Deforestation and soil erosion especially in rural areas of Mexico. In the 2022 report it was noted environmental protection laws have improved in major cities but remain unenforced or unregulated in rural regions. In Mexico, 170,000 square kilometers (65,637 sq mi) are considered "Protected Natural Areas". These include 34 biosphere reserves (unaltered ecosystems), 67 national parks , 4 natural monuments (protected in perpetuity for their aesthetic, scientific or historical value), 26 areas of protected flora and fauna, 4 areas for natural resource protection (conservation of soil, hydrological basins, and forests) and 17 sanctuaries (zones rich in diverse species). Plants indigenous to Mexico are grown in many parts of
17080-442: The shortness of their legs provides about 20% less propulsion than assessed in other birds. During flight, hummingbird feet are tucked up under the body, enabling optimal aerodynamics and maneuverability. Of those species that have been measured during flight, the top flight speeds of hummingbirds exceed 15 m/s (54 km/h; 34 mph). During courtship , some male species dive from 30 metres (100 ft) of height above
17220-556: The smallest of any bird – are incubated over 2–3 weeks in breeding season. Fed by regurgitation only from the mother, the chicks fledge about 3 weeks after hatching. The average lifespan of a ruby-throated hummingbird is estimated to be 3–5 years, with most deaths occurring in yearlings, although one banded ruby-throated hummingbird lived for 9 years and 2 months. Bee hummingbirds live 7–10 years. Although most hummingbird species live in remote habitats where their population numbers are difficult to assess, population studies in
17360-624: The state governments, and the municipal governments. The federal legislature is the bicameral Congress of the Union , composed of the Senate of the Republic and the Chamber of Deputies . The Congress makes federal law , declares war, imposes taxes, approves the national budget and international treaties, and ratifies diplomatic appointments. The federal Congress, as well as the state legislatures, are elected by
17500-412: The summer and fall. Although low-lying areas north of the Tropic of Cancer are hot and humid during the summer, they generally have lower yearly temperature averages (from 20 to 24 °C or 68.0 to 75.2 °F) because of more moderate conditions during the winter. Mexico ranks fourth in the world in biodiversity and is one of the 17 megadiverse countries . With over 200,000 different species, Mexico
17640-712: The support of Canada, Italy, Pakistan and other nine countries, which form a group informally called the Coffee Club . The Mexican Armed Forces are administered by the Secretariat of National Defense ( Secretaria de Defensa Nacional , SEDENA). There are two branches: the Mexican Army (which includes the Mexican Air Force ), and the Mexican Navy . The Secretariat of Public Security and Civil Protection has jurisdiction over
17780-510: The time. Consolidating power, President Carranza had peasant leader Emiliano Zapata assassinated in 1919. Carranza had gained the support of the peasantry during the Revolution, but once in power, he did little to institute land reform, which had motivated many to fight in the Revolution. Carranza returned some confiscated land to their original owners. President Carranza's best general, Obregón, served briefly in his administration but returned to his home state of Sonora to position himself to run in
17920-529: The uplifting of the northern Andes . In 2013, a 50-million-year-old bird fossil unearthed in Wyoming was found to be a predecessor to hummingbirds and swifts before the groups diverged. Hummingbirds split from other members of Apodiformes, the insectivorous swifts (family Apodidae) and treeswifts (family Hemiprocnidae), about 42 million years ago, probably in Eurasia . Despite their current New World distribution,
18060-574: The west, the Caribbean Sea to the southeast, and the Gulf of Mexico to the east. Human presence in Pre-Columbian Mexico dates back to 8,000 BC as one of six cradles of civilization . Mesoamerica hosted civilizations including the Olmec , Maya , Zapotec , Teotihuacan , and Purepecha . Aztec domination of the area preceded Spanish conquest of the Aztec Empire , which established
18200-574: The widest diversity of plumage color, particularly in blues, greens, and purples. Hummingbirds are the smallest mature birds, measuring 7.5–13 cm (3–5 in) in length. The smallest is the 5 cm (2.0 in) bee hummingbird , which weighs less than 2.0 g (0.07 oz), and the largest is the 23 cm (9 in) giant hummingbird , weighing 18–24 grams (0.63–0.85 oz). Noted for long beaks , hummingbirds are specialized for feeding on flower nectar , but all species also consume small insects. They are known as hummingbirds because of
18340-403: The world and integrated into their national cuisines. Some of Mexico's native culinary ingredients include maize, tomato, beans, squash, chocolate, vanilla , avocado , guava , chayote , epazote , camote , jícama , nopal , zucchini , tejocote , huitlacoche , sapote , mamey sapote , and a great variety of chiles , such as the habanero and the jalapeño . Most of these names come from
18480-757: Was a government in internal exile, but with the end of the Civil War in the United States in April 1865, the Reunified U.S. government began aiding the Mexican Republic. Two years later, the French Army withdrew its support, but Maximilian remained in Mexico. Republican forces captured him and he was executed. The "Restored Republic" saw the return of Juárez, "the personification of the embattled republic," as president. The Conservatives had been not only defeated militarily but also discredited politically for their collaboration with
18620-471: Was crushed by Juárez. Having won re-election, Juárez died in office in July 1872, and Liberal Sebastián Lerdo de Tejada became president, declaring a "religion of the state" for the rule of law, peace, and order. When Lerdo ran for re-election, Díaz rebelled against the civilian president, issuing the Plan of Tuxtepec . Díaz had more support and waged guerrilla warfare against Lerdo. On the verge of Díaz's victory on
18760-625: Was due to Napoleon Bonaparte 's invasion of Spain in 1808. Hidalgo and some of his soldiers were eventually captured, Hidalgo was defrocked, and they were executed by firing squad on 31 July 1811. The first 35 years after Mexico's independence were marked by political instability and the changing of the Mexican state from a transient monarchy to a fragile federated republic. There were military coups d'état, foreign invasions, ideological conflict between Conservatives and Liberals , and economic stagnation . Former Royal Army General Agustín de Iturbide became regent, as newly independent Mexico sought
18900-427: Was in question. Spain attempted to reconquer its former colony during the 1820s but eventually recognized its independence. France attempted to recoup losses it claimed for its citizens during Mexico's unrest and blockaded the Gulf Coast during the so-called Pastry War of 1838–1839. General Antonio López de Santa Anna emerged as a national hero because of his role in both these conflicts; Santa Anna came to dominate
19040-403: Was more moderate, and relations between the U.S. and Mexico vastly improved during World War II , when Mexico was a significant ally. From 1946 the election of Miguel Alemán , the first civilian president in the post-revolutionary period, Mexico embarked on an aggressive program of economic development, known as the Mexican miracle , which was characterized by industrialization, urbanization, and
19180-451: Was secular education. The Díaz government led a protracted conflict against the Yaqui that culminated with the forced relocation of thousands of Yaqui to Yucatán and Oaxaca. As the centennial of independence approached, Díaz gave an interview where he said he was not going to run in the 1910 elections, when he would be 80. Political opposition had been suppressed and there were few avenues for
19320-582: Was subsequently designated as the cinnamon hummingbird . The genus contains four species: An additional species is sometimes included: This genus formerly included many more species. A molecular phylogenetic study published in 2014 found that the large genus was polyphyletic . In the revised classification to create monophyletic genera, species were moved to Leucolia , Saucerottia , Amazilis , Uranomitra , Chrysuronia , Polyerata , Chionomesa , Elliotomyia and Chlorestes . [REDACTED] This hummingbird -related article
19460-573: Was the only Latin American member of the Organisation for Economic Co-operation and Development since it joined in 1994 until Chile gained full membership in 2010. Mexico is considered a regional power hence its presence in major economic groups such as the G8+5 and the G-20 . Since the 1990s Mexico has sought a reform of the United Nations Security Council and its working methods with
19600-490: Was used in the 1836 Constitutional Laws . The earliest human artifacts in Mexico are chips of stone tools found near campfire remains in the Valley of Mexico and radiocarbon-dated to circa 10,000 years ago. Mexico is the site of the domestication of maize, tomato, and beans , which produced an agricultural surplus. This enabled the transition from paleo-Indian hunter-gatherers to sedentary agricultural villages beginning around 5000 BC. The formative period of Mesoamerica
