Mexico

Mexico, officially the United Mexican States, is a country in North America. It is the northernmost country in Latin America, and borders the United States to the north, and Guatemala and Belize to the southeast; while having maritime boundaries with the Pacific Ocean to the west, the Caribbean Sea to the southeast, and the Gulf of Mexico to the east. Mexico covers 1,972,550 km² (761,610 sq mi), and is the thirteenth-largest country in the world by land area. With a population exceeding 130 million, Mexico is the tenth-most populous country in the world and is home to the largest number of native Spanish speakers. Mexico City is the capital and largest city, which ranks among the most populous metropolitan areas in the world.

Human presence in Mexico dates back to at least 8,000 BC. Mesoamerica, considered a cradle of civilization, was home to numerous advanced societies, including the Olmecs, Maya, Zapotecs, Teotihuacan civilization, and Purépecha. Spanish colonization began in 1521 with an alliance that defeated the Aztec Empire, establishing the colony of New Spain with its capital at Tenochtitlan, now Mexico City. New Spain became a major center of the transoceanic economy during the Age of Discovery, fueled by silver mining and its position as a hub between Europe and Asia. This gave rise to one of the largest multiracial populations in the world. The Peninsular War led to the 1810–1821 Mexican War of Independence, which ended Peninsular rule and led to the creation of the First Mexican Empire, which quickly collapsed into the short-lived First Mexican Republic. In 1848, Mexico lost nearly half its territory to the American invasion. Liberal reforms set in the Constitution of 1857 led to civil war and French intervention, culminating in the establishment of the Second Mexican Empire under Emperor Maximilian I of Austria, who was overthrown by Republican forces led by Benito Juárez. The late 19th century saw the long dictatorship of Porfirio Díaz, whose modernization policies came at the cost of severe social unrest. The 1910–1920 Mexican Revolution led to the overthrow of Díaz and the adoption of the 1917 Constitution. Mexico experienced rapid industrialization and economic growth in the 1940s–1970s, amidst electoral fraud, the Tlatelolco massacre, and economic crises. The late 20th century saw a shift towards neoliberalism, marked by the signing of the North American Free Trade Agreement (NAFTA) in 1994, amidst unrest in Chiapas.

Mexico is a federal republic with a presidential system of government, characterized by a democratic framework and the separation of powers into three branches: executive, legislative, and judicial. The federal legislature consists of the bicameral Congress of the Union, comprising the Chamber of Deputies, which represents the population, and the Senate, which provides equal representation for each state. The Constitution establishes three levels of government: the federal Union, the state governments, and the municipal governments. Mexico's federal structure grants autonomy to its 32 states, and its political system is deeply influenced by indigenous traditions and European Enlightenment ideals.

Mexico is a newly industrialized and developing country, with the world's 15th-largest economy by nominal GDP and the 13th-largest by PPP. It ranks first in the Americas and seventh in the world by the number of UNESCO World Heritage Sites. It is one of the world's 17 megadiverse countries, ranking fifth in natural biodiversity. It is a major tourist destination: as of 2022, it is the sixth most-visited country in the world, with 42.2 million international arrivals. Mexico's large economy and population, global cultural influence, and steady democratization make it a regional and middle power, increasingly identifying as an emerging power. As with much of Latin America, poverty, systemic corruption, and crime remain widespread. Since 2006, approximately 127,000 deaths have been caused by ongoing conflict between drug trafficking syndicates. Mexico is a member of United Nations, the G20, the OECD, the WTO, the APEC forum, the OAS, the CELAC, and the OEI.

Mēxihco is the Nahuatl term for the heartland of the Aztec Empire, namely the Valley of Mexico and surrounding territories, with its people being known as the Mexica. It is generally believed that the toponym for the valley was the origin of the primary ethnonym for the Aztec Triple Alliance, but it may have been the other way around. In the colonial era (1521–1821) when Mexico was known as New Spain, this central region became the Intendency of Mexico. After New Spain achieved independence from the Spanish Empire in 1821 and became a sovereign state, the Intendency came to be known as the State of Mexico, with the new country being named after its capital, Mexico City.

The country's official name has changed as the form of government has changed. The declaration of independence signed on 6 November 1813 by the deputies of the Congress of Anáhuac called the territory América Septentrional (Northern America). The 1821 Plan of Iguala also used América Septentrional. On two occasions (1821–1823 and 1863–1867), the country was known as Imperio Mexicano (Mexican Empire). All three federal constitutions (1824, 1857, and 1917, the current constitution) used the name Estados Unidos Mexicanos—or the variant Estados-Unidos Mexicanos, all of which have been translated as "United Mexican States". The phrase República Mexicana, "Mexican Republic", 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 is considered one of the six independent cradles of civilization, this era saw the origin of distinct cultural traits such as religious and symbolic traditions, maize cultivation, artistic and architectural complexes as well as a vigesimal (base 20) numeric system that spread from the Mexican cultures to the rest of the Mesoamerican cultural area. In this period, villages became more dense in terms of population, becoming socially stratified with an artisan class, and developing into chiefdoms. The most powerful rulers had religious and political power, organizing 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 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.
