Long before skyscrapers and traffic jams defined Mexico City, the Valley of Mexico was home to one of the most sophisticated civilizations in the Americas: the Aztecs. Founded in 1325, Tenochtitlán was built on an island in Lake Texcoco, a strategic location chosen after the Aztecs witnessed an eagle perched on a cactus devouring a snake—a vision that fulfilled an ancient prophecy. The city grew into a marvel of engineering, with intricate canal systems, floating gardens (chinampas), and towering temples like the Templo Mayor, dedicated to the gods Huitzilopochtli and Tlaloc.
In 1519, Hernán Cortés arrived on the shores of Mexico, and by 1521, Tenochtitlán lay in ruins. The Spanish, aided by rival Indigenous groups and devastating diseases like smallpox, overthrew the Aztec Empire. The conquerors dismantled the city’s temples, using the stones to build what would become Mexico City, the capital of New Spain. The Zócalo, today’s main square, sits atop the ruins of the Aztec ceremonial center, a literal and symbolic layering of histories.
Under Spanish rule, Mexico City became the political and religious heart of the viceroyalty. Grand cathedrals, like the Metropolitan Cathedral, and opulent palaces, such as the National Palace, were constructed to showcase Spanish dominance. The grid-like street plan imposed by the colonizers erased much of the Indigenous urban design, yet traces of Tenochtitlán’s layout persist beneath the surface.
The caste system (sistema de castas) enforced strict racial classifications, privileging Europeans over mestizos (mixed-race individuals) and Indigenous peoples. This systemic inequality echoes in today’s Mexico, where issues of race and class remain deeply intertwined. Recent movements, like the push for Indigenous rights and recognition, highlight the unresolved tensions of this colonial past.
On September 16, 1810, Miguel Hidalgo’s "Grito de Dolores" ignited the Mexican War of Independence. By 1821, Mexico was free from Spanish rule, but the young nation faced internal strife. Mexico City, as the capital, became the battleground for competing visions of the country’s future—liberal vs. conservative, secular vs. religious.
The early 20th century brought another upheaval: the Mexican Revolution (1910–1920). Peasants, workers, and intellectuals fought against the dictatorship of Porfirio Díaz, demanding land reform and social justice. Mexico City swelled with refugees and migrants, transforming into a sprawling metropolis. Murals by Diego Rivera, José Clemente Orozco, and David Alfaro Siqueiros later adorned the city’s walls, turning art into a tool for political storytelling.
With over 21 million people in its metro area, Mexico City is one of the largest cities in the world. Its rapid expansion has led to severe overcrowding, pollution, and water scarcity. The sinking of the city—up to 20 inches per year in some areas—due to the over-extraction of groundwater is a stark reminder of its unsustainable growth. Meanwhile, wealth disparities are glaring: luxury high-rises in Polanco contrast with informal settlements in Iztapalapa.
Mexico City’s air quality is among the worst globally, with smog often obscuring views of the surrounding mountains. Climate change exacerbates these issues, with hotter temperatures and unpredictable rainfall. The government’s efforts, like the "Hoy No Circula" program (restricting car use), have had mixed results. Activists are pushing for greener solutions, such as expanding public transit and protecting the city’s few remaining wetlands.
Despite its challenges, Mexico City thrives as a cultural powerhouse. From the Frida Kahlo Museum in Coyoacán to the punk scene in Tepito, creativity pulses through its streets. The 2017 earthquake, which killed hundreds, also revealed the city’s communal spirit, as volunteers rushed to rescue survivors. As Mexico City grapples with its past and future, one thing is clear: its history is not just buried beneath the pavement—it’s alive in every corner.
