Mexico

Mexico (Spanish: México [ˈmexiko] ( listen); Nahuatl languages: Mēxihco), officially the United Mexican States (Spanish: Estados Unidos Mexicanos, listen ), is a federal republic in the southernmost portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world.
With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, and Tijuana.
Mexico has the 15th largest nominal GDP and the 11th largest by purchasing power parity. The Mexican economy is strongly linked to those of its 1994 North American Free Trade Agreement (NAFTA) partners, especially the United States. In 1994, Mexico became the first Latin American member of the Organisation for Economic Co-operation and Development (OECD). It is classified as an upper-middle income country by the World Bank and a newly industrialized country by several analysts. The country is considered both a regional power and a middle power, and is often identified as an emerging global power. Due to its rich culture and history, Mexico ranks first in the Americas and seventh in the world for number of UNESCO World Heritage Sites. Mexico is an ecologically megadiverse country, ranking fourth in the world for its biodiversity. Mexico has many tourists: in 2016, it was the eighth most-visited country in the world, with 35 million international arrivals. Mexico is a member of the United Nations (UN), the World Trade Organization (WTO), the G8+5, the G20, the Uniting for Consensus group of the UN, and the Pacific Alliance trade bloc. By 2050, Mexico could potentially become the world's fifth or seventh largest economy.Pre-Columbian Mexico dates to about 8000 BC and is identified as one of five cradles of civilization and was home to many advanced Mesoamerican civilizations such as the Olmec, Toltec, Teotihuacan, Zapotec, Maya, and Aztec before first contact with Europeans. In 1521, the Spanish Empire conquered and colonized the territory from its politically powerful base in Mexico-Tenochtitlan (part of Mexico City), which was administered as the viceroyalty of New Spain. Three centuries later, the territory became a nation state following its recognition in 1821 after the colony's Mexican War of Independence. The post-independence period was tumultuous, characterized by economic inequality and many intense political changes. The Mexican–American War (1846–1848) led to a territorial cession of the extant northern territories to the United States. The Pastry War, the Franco-Mexican War, a civil war, two empires, and the Porfiriato occurred in the 19th century. The Porfiriato was ended by the start of the Mexican Revolution in 1910, which culminated with the promulgation of the 1917 Constitution and the emergence of the country's current political system as a democratic republic.
