The site of several advanced Amerindian civilizations - including the Olmec, Toltec, Teotihuacan, Zapotec, Maya, and Aztec - Mexico was conquered and colonized by Spain in the early 16th century. Administered as the Viceroyalty of New Spain for three centuries, it achieved independence early in the 19th century. Elections held in 2000 marked the first time since the 1910 Mexican Revolution that an opposition candidate - Vicente FOX of the National Action Party (PAN) - defeated the party in government, the Institutional Revolutionary Party (PRI). He was succeeded in 2006 by another PAN candidate Felipe CALDERON, but Enrique PENA NIETO regained the presidency for the PRI in 2012. Left-leaning antiestablishment politician and former mayor of Mexico City (2000-05) Andres Manuel LOPEZ OBRADOR, from the National Regeneration Movement (MORENA), became president in December 2018.

The global financial crisis in late 2008 caused a massive economic downturn in Mexico the following year, although growth returned quickly in 2010. Ongoing economic and social concerns include low real wages, high underemployment, inequitable income distribution, and few advancement opportunities for the largely indigenous population in the impoverished southern states. Since 2007, Mexico's powerful drug-trafficking organizations have engaged in bloody feuding, resulting in tens of thousands of drug-related homicides.

volcanism: volcanic activity in the central-southern part of the country; the volcanoes in Baja California are mostly dormant; Colima (3,850 m), which erupted in 2010, is Mexico's most active volcano and is responsible for causing periodic evacuations of nearby villagers; it has been deemed a Decade Volcano by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to its explosive history and close proximity to human populations; Popocatepetl (5,426 m) poses a threat to Mexico City; other historically active volcanoes include Barcena, Ceboruco, El Chichon, Michoacan-Guanajuato, Pico de Orizaba, San Martin, Socorro, and Tacana; see note 2 under "Geography - note"

Mexico's $2.4 trillion economy – 11th largest in the world - has become increasingly oriented toward manufacturing since the North American Free Trade Agreement (NAFTA) entered into force in 1994. Per capita income is roughly one-third that of the US; income distribution remains highly unequal.

Mexico has become the US' second-largest export market and third-largest source of imports. In 2017, two-way trade in goods and services exceeded $623 billion. Mexico has free trade agreements with 46 countries, putting more than 90% of its trade under free trade agreements. In 2012, Mexico formed the Pacific Alliance with Peru, Colombia, and Chile.

Mexico's current government, led by President Enrique PENA NIETO, has emphasized economic reforms, passing and implementing sweeping energy, financial, fiscal, and telecommunications reform legislation, among others, with the long-term aim to improve competitiveness and economic growth across the Mexican economy. Since 2015, Mexico has held public auctions of oil and gas exploration and development rights and for long-term electric power generation contracts. Mexico has also issued permits for private sector import, distribution, and retail sales of refined petroleum products in an effort to attract private investment into the energy sector and boost production.

Since 2013, Mexico’s economic growth has averaged 2% annually, falling short of private-sector expectations that President PENA NIETO’s sweeping reforms would bolster economic prospects. Growth is predicted to remain below potential given falling oil production, weak oil prices, structural issues such as low productivity, high inequality, a large informal sector employing over half of the workforce, weak rule of law, and corruption. Mexico’s economy remains vulnerable to uncertainty surrounding the future of NAFTA — because the United States is its top trading partner and the two countries share integrated supply chains — and to potential shifts in domestic policies following the inauguration of a new a president in December 2018.

abundant rainfall in recent years along much of the Mexico-US border region has ameliorated periodically strained water-sharing arrangements; the US has intensified security measures to monitor and control legal and illegal personnel, transport, and commodities across its border with Mexico; Mexico must deal with thousands of impoverished Guatemalans and other Central Americans who cross the porous border looking for work in Mexico and the US; Belize and Mexico are working to solve minor border demarcation discrepancies arising from inaccuracies in the 1898 border treaty
