Mexico is a large country in the southern part of North America, bordered by the United States to the north and by Guatemala and Belize to the south. Its terrain runs from high central plateaus ringed by mountains to tropical coasts on the Pacific Ocean and the Gulf of Mexico. Heir to ancient civilisations and three centuries of Spanish rule, Mexico is the most populous Spanish-speaking country in the world and a centre of art, music, and food.
Long before European contact, Mexico was home to advanced civilisations, including the Olmec, the Maya with their writing and astronomy, and the Aztecs, whose capital Tenochtitlan stood where Mexico City is today. In 1521 Spanish forces under Hernan Cortes, allied with Indigenous enemies of the Aztecs and aided by introduced diseases, toppled the Aztec Empire, beginning three hundred years of colonial rule as New Spain. Mexico won independence in 1821 after a long war.

According to Aztec tradition, their wandering people were told by their god to settle where they found an eagle perched on a cactus devouring a serpent. They saw the sign on an island in a lake and there founded Tenochtitlan, the city that became their capital. The tale is a foundational national myth, pictured at the centre of the modern flag, but as literal history the omen and its details belong to legend rather than the documented record, even as the city's real existence and grandeur are well established.

Mexico is a land of dramatic contrasts, from northern deserts and the long Sierra Madre mountain ranges to tropical jungles and beaches in the south. Much of the population lives on a high central plateau, where the climate is temperate despite the latitude. The country sits in a seismically active zone and has many volcanoes, and its varied environments make it one of the most biologically diverse nations on Earth.

The Mexican flag has three vertical bands of green, white, and red, with the national coat of arms at its centre. The emblem shows a golden eagle perched on a cactus, devouring a serpent, drawn directly from the Aztec founding legend. The colours are commonly understood today to stand for hope, unity, and the blood of national heroes, and the central eagle ties the modern nation directly to its ancient roots.
Mexico is overwhelmingly Roman Catholic, a faith brought by the Spanish that fused with Indigenous traditions to create something distinctly Mexican. Its most powerful symbol is the Virgin of Guadalupe, venerated across the country. That blending is vivid in the Day of the Dead, when families honour deceased relatives with altars, marigolds, and offerings, a celebration recognised by UNESCO that joins Catholic observance with pre-Hispanic beliefs about death and remembrance.
Mexican cuisine is so distinctive that it is recognised by UNESCO as intangible cultural heritage. It rests on an ancient trinity of corn, beans, and chili peppers, with corn appearing as tortillas, tamales, and countless other forms. Dishes range from simple, perfect tacos to the complex sauces known as mole, which can blend dozens of ingredients including chilies and chocolate. Many of these ingredients, including the tomato, the avocado, and chocolate itself, were unknown to the wider world before they spread from Mexico.
Mexico is the birthplace of many staple foods that now feed the world, above all corn, domesticated here thousands of years ago. Today it is the leading global exporter of avocados and a major supplier of tomatoes, chili peppers, and berries, much of it bound for the United States. Sugarcane, coffee, and tropical fruits are also important. The country's wide range of climates, from desert to tropics, allows an unusually broad variety of crops.
Mexico's path to nationhood was forged in two great upheavals. The War of Independence began in 1810 with the Cry of Dolores, a call to arms by the priest Miguel Hidalgo, and ended in 1821 with the birth of an independent nation. A century later, the Mexican Revolution that erupted in 1910 swept away a long dictatorship, redistributed land, and shaped the modern state and its sense of identity.

Mexico has around 129 million people, making it the most populous Spanish-speaking nation in the world. Most Mexicans are mestizo, of mixed Indigenous and European descent, and the country retains large Indigenous communities speaking dozens of native languages. The population is concentrated on the central plateau, especially in the vast Greater Mexico City area, one of the largest urban regions on the planet. Migration, much of it toward the United States, has long shaped Mexican society and economy.
