A Short History of Mexico

From its beginnings to today — 13 eras that shaped it.

• First Peoples — The first humans arrived in what is now Mexico during the last Ice Age, gradually populating the entire region as the climate warmed. These early peoples hunted megafauna like mammoths and mastodons while gathering plants, seeds, and shellfish. Over millennia, they developed increasingly sophisticated tools and began experimenting with cultivating wild plants. By around 7000 BC, the domestication of maize, beans, and squash began in central Mexico, marking the shift from hunting to farming that would transform the continent.
• Formative Period — With agriculture established, permanent settlements emerged across Mesoamerica, and populations grew dramatically. The Olmec civilization, flourishing along Mexico's Gulf Coast from roughly 1500 to 400 BC, became the region's first major culture, creating monumental stone sculptures and establishing trade networks. They developed early forms of writing and the Mesoamerican ball game, practices that would persist for millennia. Their influence spread religious concepts, artistic styles, and technologies throughout Mesoamerica, laying the intellectual and spiritual foundations for all civilizations that followed.
• Classic Maya — During the Classic period, Maya city-states in southern Mexico, Guatemala, and Central America achieved remarkable heights of civilization. They built soaring pyramid-temples, elaborate palaces, and intricate ball courts while developing sophisticated hieroglyphic writing and a mathematical system including the concept of zero. Maya astronomers tracked celestial bodies with stunning accuracy and created calendars of extraordinary precision. However, by around 900 AD, the southern cities mysteriously collapsed, though Maya civilization persisted in the north and continued in smaller settlements and city-states.
• Post-Classic Mesoamerica — After the Classic collapse, the center of Mesoamerican power shifted northward to central Mexico. Tula became the dominant city-state, ruled by the Toltecs, who were known as fierce warriors and skilled craftsmen. The Toltecs spread their influence and cultural practices across a vast region through conquest and trade. They worshipped Quetzalcoatl, the feathered serpent god, and left behind remarkable architecture and sculptures that would later inspire the peoples who replaced them.
• Aztec Rise — The Aztecs, or Mexica as they called themselves, arrived in the Valley of Mexico as a nomadic, warrior people searching for a prophesied homeland. Rejected by more established cities, they were permitted to settle on swampy islands in Lake Texcoco, where they began building their city of Tenochtitlan around 1325 AD. Through military skill, political cunning, and ingenious engineering—including the creation of chinampas, or floating gardens—they transformed their unlikely location into a thriving metropolis. Within two centuries, Tenochtitlan would become the largest city in the world, surpassing even the great European capitals in size and sophistication.
• Aztec Empire — From their island capital, the Aztecs launched military campaigns that brought much of Mesoamerica under their control, creating a tribute empire that enriched Tenochtitlan with goods, gold, and captives. The city became an architectural marvel with towering temples, grand palaces, intricate canal systems, and a population that may have exceeded 200,000 people. Aztec society was rigidly hierarchical, with the Tlatoani, or emperor, at the apex, followed by nobility, merchants, artisans, farmers, and slaves. Religion permeated every aspect of life, with the Aztecs believing they had a sacred duty to keep the sun moving across the sky through human sacrifice, a practice that would ultimately make them feared and hated by subject peoples.
• Spanish Conquest — When Hernán Cortés landed on Mexico's coast with roughly 600 men, he quickly realized that conquest required more than Spanish firepower. He exploited grievances among Aztec subject peoples, particularly the Tlaxcalans, who resented paying tribute and providing victims for sacrifice. Montezuma II's initial hesitation and hospitality gave Cortés a foothold in Tenochtitlan, though the Spaniards were soon besieged. After a catastrophic plague of smallpuff devastated the Aztec population—a disease the indigenous peoples had no immunity to—Cortés returned with reinforcements and laid siege to the city for nearly three months, finally destroying Tenochtitlan and executing Montezuma's successor in 1521.
• Colonial Mexico — The Spanish established the Viceroyalty of New Spain, with Mexico City built atop Tenochtitlan's ruins as its capital. They subjected the indigenous population to encomienda—a system granting colonists control over native labor—and forced them to work silver mines that made Spain fabulously wealthy. The Catholic Church became a powerful institution, converting millions of indigenous people and often blending Christian practices with pre-Columbian beliefs. A rigid racial caste system developed, with pure-blood Spaniards at the top, mixed-race mestizos and mulatos in the middle, and indigenous peoples and African slaves at the bottom, creating deep social tensions that would persist for centuries.
• Mexican Independence War — The war began on September 16, 1810, when Father Miguel Hidalgo issued the Grito de Dolores, calling for indigenous and mestizo uprising against Spanish domination. Early insurgent forces achieved surprising successes, but Spanish forces brutally suppressed the rebellion, executing Hidalgo and other leaders. The fight dragged on for over a decade, with royalist troops and independence forces clashing repeatedly. Finally, in 1821, independence was achieved, though the transition was chaotic and the new Mexican nation remained unstable, burdened by debt, social division, and territorial disputes with its powerful northern neighbor, the United States.
• U.S.-Mexican War — Conflict erupted when the United States, driven by Manifest Destiny ideology, invaded Mexico over the disputed Texas border. American forces proved overwhelming, eventually occupying Mexico City itself. The Treaty of Guadalupe Hidalgo forced Mexico to cede more than half its territory—present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming—to the United States in exchange for $15 million. The loss was traumatic and created lasting resentment, transforming Mexico's relationship with its northern neighbor and leaving the nation economically devastated and politically fractured.
• Mexican Revolution — Beginning as a rebellion against the autocratic presidency of Porfirio Díaz, the Mexican Revolution evolved into a comprehensive social upheaval involving peasants, workers, intellectuals, and regional strongmen. Millions died in fighting and famine as various factions competed for power, each with different visions for Mexico's future. The revolution destroyed the old landowning elite, distributed land to peasants through ejidos (communal farms), and created a new political order that would dominate the 20th century. A new constitution established workers' rights, secular education, and presidential term limits, fundamentally reshaping Mexico's legal and social framework.
• Post-Revolutionary Stability — After decades of violence, the PRI (Partido Revolucionario Institucional) gradually consolidated power and maintained stability through a unique system of corporatism and controlled democracy. The party distributed land to millions of peasants, invested in infrastructure and industry, and promoted a vibrant national culture celebrating indigenous heritage and revolutionary ideals. Artists like Diego Rivera and Frida Kahlo created powerful murals and paintings that made Mexican culture internationally renowned. Economic growth improved living standards for many, though inequality persisted and the political system became increasingly authoritarian and corrupt beneath its facade of democratic legitimacy.
• Modern Mexico — The late 20th century brought economic turbulence, including severe debt crises and currency collapses that devastated the middle class. The 1985 Mexico City earthquake exposed government incompetence and sparked civil society activism. After 71 years of single-party rule, the PRI lost presidential elections to conservative and left-wing alternatives in 2000 and beyond, ending its monopoly on power. Contemporary Mexico faces persistent challenges including organized crime's influence over vast territories, extreme inequality, migration pressures, and political polarization, yet it remains a major economy and cultural force with a young population and growing democratic participation despite its many difficulties.
