Mexico City hasn’t survived seven centuries by accident. It’s been drowned, burned, conquered, bombed, shaken by earthquakes, and buried under its own smog — and somehow it keeps coming back bigger, louder, and more alive than before. Understanding this city’s history isn’t optional if you want to understand the city itself. Every sinking building, every cathedral built on top of a pyramid, every protest march down Paseo de la Reforma is a conversation with the past.
So here’s the full story — from a swampy island to a metropolis of 22 million — told in roughly chronological order, with all the conquests, revolutions, disasters, and reinventions that made Mexico City what it is today.
Before the Aztecs: The Valley’s First Civilizations
People have lived in the Valley of Mexico for thousands of years before anyone built Tenochtitlan. The valley — a high-altitude basin ringed by volcanoes at about 2,240 meters (7,350 feet) above sea level — offered fertile soil, freshwater lakes, and a mild climate that made it one of the most attractive places to settle in all of Mesoamerica.
The earliest significant civilization in the valley was Cuicuilco, which thrived in the southern part of modern Mexico City (near what’s now Tlalpan) from roughly 800 BC to around 250 AD. Cuicuilco had one of the first large pyramids in central Mexico — a distinctive round structure that you can still visit today. The city was doing just fine until the Xitle volcano erupted around 245-315 AD and buried much of the settlement under a thick lava field called the Pedregal. That eruption essentially ended Cuicuilco as a power and sent its refugees scattering across the valley.
To the northeast, Teotihuacan rose to become one of the largest cities in the ancient world, peaking around 450 AD with an estimated population of 100,000-200,000 people. Its massive Pyramid of the Sun and Pyramid of the Moon dominated the landscape, and its influence reached as far as Guatemala. Then, around 750 AD, Teotihuacan mysteriously collapsed — likely due to internal revolt, drought, or some combination — and its people dispersed.
After Teotihuacan’s fall, the Toltecs became the dominant force in the valley, ruling from their capital of Tollan (modern Tula) until about 1200 AD. When the Toltecs also collapsed, a power vacuum opened up. Waves of Nahuatl-speaking peoples migrated into the Valley of Mexico, founding competing city-states around the shores of Lake Texcoco. By the 1300s, the valley was a patchwork of ambitious, frequently warring mini-kingdoms — and the stage was set for the Aztecs.
The Founding of Tenochtitlan (1325)
The Mexica — the people we usually call the Aztecs — were latecomers and underdogs. They were one of the last Nahuatl-speaking groups to arrive in the valley, and nobody wanted them there. According to their own accounts, they’d been wandering for roughly 260 years after leaving a mythical homeland called Aztlan (described as an island in the middle of a lake — a detail that makes the later founding of their capital feel almost predestined).
Their migration story is one of the great epics of the Americas. Led by their patron god Huitzilopochtli, the Mexica arrived at Chapultepec on the western edge of Lake Texcoco but were driven away by hostile neighbors. They fought, lost, got enslaved by the Colhuas, impressed them in battle against Xochimilco, then got expelled again after sacrificing captured hearts to Huitzilopochtli. (The Mexica’s devotion to human sacrifice made them unpopular at parties, so to speak.)
Finally, around 1325, they settled on a small, swampy island in the western part of Lake Texcoco — the one place nobody else wanted. According to legend, Huitzilopochtli told them to look for a sign: an eagle perched on a nopal cactus with a snake in its beak. They found it on that island, and that image has been on the Mexican flag ever since independence in 1821.
It was, by any reasonable assessment, a terrible place to build a city. The island was tiny, marshy, and surrounded by brackish water. But the Mexica turned those disadvantages into strengths with a combination of engineering brilliance and sheer stubbornness that would define the city for centuries to come.
Tenochtitlan at Its Height
What the Mexica built on that swampy island was nothing short of extraordinary. Through a system of chinampas — floating gardens created by layering mud, reeds, and vegetation onto shallow lake beds — they literally expanded their island, creating new agricultural land and new neighborhoods at the same time. The chinampas were staggeringly productive, allowing multiple harvests per year and feeding a rapidly growing population.
Three great causeways connected the island city to the mainland: one to the north (Tepeyac), one to the west (Tlacopan), and one to the south (Iztapalapa). These causeways doubled as aqueducts and dikes, and they included removable bridges that could be raised to defend the city. A separate aqueduct brought fresh water from the springs of Chapultepec, since the lake water itself was too salty to drink.
At the center of the city stood the Templo Mayor — a massive double pyramid dedicated to Huitzilopochtli (god of war and sun) and Tlaloc (god of rain). You can visit its excavated ruins today, right next to the Metropolitan Cathedral in the Historic Center. The sacred precinct around the Templo Mayor included dozens of other temples, a ball court, a skull rack (tzompantli), and the palaces of the rulers.
The great market of Tlatelolco, Tenochtitlan’s sister city on an adjacent island, was one of the largest marketplaces in the world. Spanish conquistador Bernal Diaz del Castillo described it as bigger than anything in Europe, with 60,000 people trading daily in everything from cacao beans and gold to jaguar skins and slaves.
In 1430, Tenochtitlan formed the Triple Alliance with the city-states of Texcoco and Tlacopan, creating what we call the Aztec Empire. Through military conquest and strategic alliances, the Triple Alliance expanded to control much of central and southern Mexico, from the Gulf Coast to the Pacific. Tribute flowed into Tenochtitlan from conquered peoples: gold, jade, feathers, cotton, cacao, and food. By 1519, the city’s population had reached somewhere between 150,000 and 200,000 — making it one of the five largest cities on Earth at the time, comparable to Paris or Constantinople.
The Mexica emperor Moctezuma II ruled from a palace so enormous that the Spanish soldiers who later saw it compared it favorably to anything in Spain. It had aviaries, zoos, gardens, and armories. The streets were clean (the city employed a thousand sweepers). The architecture was imposing. And the whole thing sat on a lake, connected to the mainland by causeways, looking like something out of a fantasy novel. When the Spanish first saw it from the mountains above the valley in November 1519, they couldn’t believe their eyes.
The Spanish Conquest (1519-1521)
Hernan Cortes landed on the Gulf Coast of Mexico in February 1519 with about 500 soldiers, 16 horses, and a handful of cannons. Within two and a half years, the Aztec Empire was finished and Tenochtitlan lay in ruins. It remains one of the most dramatic and consequential military campaigns in human history.
Cortes was ambitious, ruthless, and lucky. He quickly realized that the Aztecs had made plenty of enemies through their system of tribute and human sacrifice. Indigenous groups like the Tlaxcalans, who had been fighting the Aztecs for generations, were happy to ally with anyone who might help them settle the score. By the time Cortes marched on Tenochtitlan, his force included thousands of indigenous warriors.
Moctezuma II famously allowed Cortes to enter Tenochtitlan peacefully in November 1519 — a decision that historians have debated for five hundred years. Was he hedging his bets? Did he believe Cortes might be connected to the returning god Quetzalcoatl? Was it a diplomatic calculation? Whatever his reasoning, it didn’t work out. Cortes took Moctezuma hostage inside his own palace.
Things fell apart in June 1520. While Cortes was away dealing with a rival Spanish expedition, his lieutenant Pedro de Alvarado massacred Aztec nobles during a religious festival at the Templo Mayor. The city erupted. When Cortes returned, the Spanish were trapped inside the city with a furious population. Moctezuma was killed — either by his own people (the Spanish account) or by the Spanish themselves (the indigenous account). On the night of June 30, 1520, the Spanish tried to sneak out along the Tlacopan causeway. They were discovered, and in the ensuing battle, Cortes lost about 600 Spanish soldiers and possibly thousands of indigenous allies. The Spanish called it La Noche Triste — the Night of Sorrows.
But Cortes didn’t give up. He retreated to Tlaxcala, rebuilt his forces, and constructed thirteen small warships to use on the lake. In May 1521, he returned and laid siege to Tenochtitlan. The siege lasted 75 brutal days. Cortes cut the aqueducts, blockaded the causeways, and used his ships to control the lake. Smallpox — brought by the Spanish and devastating to a population with no immunity — ravaged the city’s defenders. The new Aztec emperor Cuauhtemoc fought tenaciously, but by August 13, 1521, it was over. Tenochtitlan was destroyed. Tens of thousands were dead, many from disease. The Aztec Empire, which had seemed invincible just two years earlier, had ceased to exist.
Rebuilding on Ruins: The Birth of Colonial Mexico City (1521-1600)
Cortes made a decision that would shape the next five centuries: rather than abandon the ruins of Tenochtitlan, he would build the new Spanish colonial capital directly on top of them. It was a political statement — proof of Spanish dominance — but also a practical one. The location was centrally positioned, already connected by roads and causeways, and had existing infrastructure.
Indigenous laborers (many of them former subjects of the Aztec Empire) were forced to demolish the remaining Aztec structures and use the stones to build Spanish colonial buildings. The Zocalo — Mexico City’s enormous main square — was built directly over the Aztec ceremonial center. The Metropolitan Cathedral was constructed using stones from the Templo Mayor. Spanish mansions and government buildings went up on the foundations of Aztec palaces. This layering of civilizations is literal: dig almost anywhere in the Historic Center and you’ll find Aztec ruins beneath colonial foundations.
The city was redesigned on a Spanish grid pattern, with the Plaza Mayor (now the Zocalo) at its center. Spanish settlers lived in the core, called the traza, while indigenous residents were pushed to surrounding neighborhoods called parcialidades. This racial segregation shaped the city’s geography for centuries — and some of those neighborhoods retain their indigenous Nahuatl names to this day (Coyoacan, Iztapalapa, Xochimilco, Tlalpan).
The University of Mexico was founded in 1553, making it one of the oldest universities in the Americas. Religious orders — Franciscans, Dominicans, Augustinians, Jesuits — built massive churches and monasteries throughout the city. The Inquisition established its headquarters here in 1571, targeting heretics, crypto-Jews, and anyone whose beliefs didn’t align with Catholic orthodoxy. Its palace still stands on the western side of the Alameda Central.
Colonial Mexico City: City of Palaces and Floods (1600-1810)
As the capital of the Viceroyalty of New Spain — which at its height stretched from Central America to the modern American Southwest, plus the Philippines — Mexico City became one of the wealthiest and most important cities in the world. Silver from mines in Zacatecas, Guanajuato, and Taxco flowed through the capital on its way to Spain. Great merchant houses established themselves here, and the colonial elite built palaces so grand that the city earned the nickname “City of Palaces” — a description often attributed to the German scientist Alexander von Humboldt, who visited around 1803.
But the city had a chronic, life-threatening problem: flooding. Remember, the Spanish had built their capital on an island in a lake. The Aztecs had managed the water brilliantly with dikes, causeways, and drainage systems. The Spanish, not fully understanding or not caring about these systems, dismantled much of the infrastructure. The result was catastrophic flooding. In 1555, 1580, 1604, and — most devastating of all — 1629, the city was inundated. The flood of 1629 left parts of the city under water for five years. Five years. There was serious discussion about abandoning the city entirely and rebuilding somewhere else.
Instead, the colonial government embarked on one of the most ambitious hydraulic engineering projects of the era: the Desague, a massive effort to drain the lakes surrounding the city. This project, begun in the early 1600s and continuing in various forms for over 300 years, gradually transformed the Valley of Mexico from a landscape of interconnected lakes into the dry basin we see today. It solved the flooding problem (mostly) but created new ones — subsidence, water scarcity, and ecological destruction — that Mexico City is still dealing with.
By the late colonial period, Mexico City’s population had reached about 130,000. The society was rigidly stratified by race: peninsulares (Spaniards born in Spain) at the top, criollos (Spaniards born in Mexico) just below, then a complex hierarchy of mixed-race castas, with indigenous people and Africans at the bottom. This system bred resentment, particularly among the criollos, who were wealthy and educated but excluded from the highest positions of power. That resentment would eventually explode.
Independence: From Colony to Republic (1810-1821)
The Mexican War of Independence started not in Mexico City but in the small town of Dolores, Guanajuato, in the early hours of September 16, 1810. Father Miguel Hidalgo rang the church bell and issued his famous Grito de Dolores — a call to arms against Spanish rule. His ragtag army of indigenous and mestizo fighters grew rapidly, winning early victories and marching toward the capital.
Hidalgo actually reached the outskirts of Mexico City in late October 1810 but made the fateful decision not to attack. He may have feared that an assault on the heavily defended capital would lead to a massacre of his poorly armed followers. Whatever his reasoning, it was a turning point. Spanish forces regrouped, and Hidalgo was captured and executed in 1811. His head was displayed on a granary in Guanajuato as a warning.
The independence movement continued under Jose Maria Morelos, a mestizo priest and far more capable military leader than Hidalgo. Morelos articulated a vision of an independent, egalitarian Mexico with racial equality and land reform — ideas that were radical for the time and wouldn’t be fully realized for another century. He, too, was captured and executed, in 1815.
Independence finally came in 1821, and it arrived from an unlikely direction. Agustin de Iturbide, a criollo military officer who had spent years fighting against the independence movement, switched sides when he realized that political changes in Spain threatened the privileges of the colonial elite. His Plan de Iguala — guaranteeing independence, Catholicism, and equality between Spaniards and Mexicans — attracted broad support. On September 27, 1821, Iturbide’s Army of the Three Guarantees marched triumphantly into Mexico City. Spanish rule was over.
Iturbide crowned himself Emperor Agustin I in 1822, but his reign lasted less than a year before he was overthrown. Mexico became a republic in 1824, with Mexico City as its capital. The next half-century would be absolute chaos.
The Turbulent 19th Century (1821-1876)
The first fifty years of Mexican independence were, to put it mildly, a mess. Between 1824 and 1857, Mexico had over fifty different governments and eleven presidents — including Antonio Lopez de Santa Anna, who served as president an astounding eleven times. The country lurched between centralism and federalism, liberalism and conservatism, dictatorship and anarchy.
The most traumatic event was the Mexican-American War (1846-1848). U.S. forces invaded Mexico, and in September 1847, American troops stormed Chapultepec Castle — then serving as a military academy. According to Mexican tradition, six teenage cadets (the Ninos Heroes) chose to die rather than surrender, with the last wrapping himself in the Mexican flag and leaping from the ramparts. U.S. forces occupied Mexico City from September 1847 to June 1848. The Treaty of Guadalupe Hidalgo forced Mexico to cede roughly half its territory — including California, Arizona, New Mexico, Texas, and parts of Colorado, Utah, and Nevada — to the United States. It was a national humiliation that Mexico has never fully forgotten.
Then came the Reform War (1858-1861), a civil war between Liberals and Conservatives over the role of the Catholic Church, land reform, and the nature of the Mexican state. The Liberals, led by Benito Juarez — a Zapotec indigenous man from Oaxaca who became one of Mexico’s greatest presidents — eventually won. His Reform Laws secularized much of church property, separated church and state, and established civil marriage and religious freedom.
But Mexico’s troubles weren’t over. In 1861, Juarez suspended foreign debt payments. France, under Napoleon III, used this as a pretext to invade, installing the Austrian Archduke Ferdinand Maximilian as Emperor of Mexico in 1864. Maximilian and his wife Carlota set up court in Chapultepec Castle, redecorated it in European style (you can still see their rooms today), and laid out the grand boulevard connecting the castle to the city center — the avenue we now know as Paseo de la Reforma. Maximilian was by most accounts a decent, well-meaning man who genuinely tried to govern fairly. He was also hopelessly out of his depth. When Napoleon III withdrew French troops in 1866 under American pressure, Maximilian’s empire crumbled. He was captured, court-martialed, and executed by firing squad in Queretaro in 1867. Carlota, who had gone to Europe to plead for help, went insane and spent the rest of her life in a Belgian castle, never learning of her husband’s death (she died in 1927).
Juarez returned to Mexico City triumphant. He died in office in 1872, and after a brief power struggle, General Porfirio Diaz took control of the country in 1876.
The Porfiriato: Modernization at a Price (1876-1910)
Porfirio Diaz ruled Mexico for over thirty years (1876-1880, then 1884-1911), a period known as the Porfiriato. He transformed Mexico City from a somewhat provincial capital into a modern, European-style metropolis — but at an enormous social cost.
Diaz was obsessed with making Mexico look “civilized” by European standards. He poured money into Mexico City’s infrastructure: electric streetcars, paved streets, telephone lines, a drainage system that finally addressed the centuries-old flooding problem (the Gran Canal del Desague was completed in 1900). He commissioned grand public buildings in the French Beaux-Arts style, including what would eventually become the Palace of Fine Arts (started in 1904 but not completed until 1934 because of the revolution and — ironically — because the heavy building kept sinking into the soft lakebed).
Paseo de la Reforma was extended and lined with monuments, statues, and grand mansions. New neighborhoods — called colonias — were developed for the wealthy: Colonia Juarez, Roma, and Condesa were all products of the Porfiriato, designed in the fashionable European style with tree-lined boulevards, parks, and elegant architecture. The Angel of Independence monument on Reforma, perhaps the most iconic symbol of modern Mexico City, was inaugurated in 1910 to celebrate the centennial of independence.
But underneath the gilded surface, Mexico was a powder keg. Diaz’s modernization was financed by foreign capital, primarily American and British, which controlled Mexico’s mines, railroads, and oil fields. The hacienda system concentrated land ownership in a tiny elite: by 1910, roughly 97% of rural families owned no land at all. Workers had few rights. Political dissent was crushed. The press was censored. Elections were rigged. Diaz’s famous motto was “pan o palo” — bread or the stick.
At the start of the 20th century, Mexico City’s population was about 500,000. It was beautiful, modern, and deeply unequal. Revolution was inevitable.
The Mexican Revolution (1910-1920)
The Mexican Revolution began when Francisco Madero — a wealthy, idealistic landowner from the north — challenged Diaz in the 1910 presidential election. When Diaz had Madero arrested and declared himself the winner, Madero called for armed revolution. Diaz, aging and out of touch, was forced into exile in May 1911. He sailed to Paris, where he reportedly said: “Madero has unleashed a tiger; let’s see if he can ride it.” He couldn’t.
What followed was a decade of civil war, betrayal, and slaughter that killed an estimated one to two million people — roughly one in ten Mexicans. Madero was overthrown and murdered in 1913 in a coup orchestrated by General Victoriano Huerta with the complicity of the U.S. ambassador. Revolutionary factions — Venustiano Carranza’s Constitutionalists, Pancho Villa’s Division of the North, Emiliano Zapata’s peasant army from Morelos — fought each other as much as they fought the government.
Mexico City changed hands multiple times during the revolution. Zapata’s forces and Villa’s forces both occupied the capital at different points. The famous photograph of Villa sitting in the presidential chair, grinning, with Zapata beside him, was taken in the National Palace on the Zocalo in December 1914. But neither Villa nor Zapata was interested in governing from a desk, and they left the capital to continue fighting in the countryside.
Carranza eventually prevailed, and a new Constitution was written in 1917 — one of the most progressive documents of its era, establishing land reform, labor rights, secular education, and national ownership of natural resources. But violence continued. Zapata was assassinated in 1919 (lured into an ambush). Carranza was killed in 1920. Villa was assassinated in 1923. The revolution ate its own.
The Revolution Monument in the city center — originally meant to be the new legislative palace under Diaz but left unfinished during the revolution — was eventually completed in the 1930s as a memorial. Its massive stone arches contain the remains of several revolutionary leaders, including Villa and Carranza.
Post-Revolution: Building a Modern Nation (1920-1960)
After the revolution, Mexico’s new leaders faced the enormous task of rebuilding a shattered country. They used Mexico City as their canvas. The post-revolutionary government launched ambitious public works, education campaigns, and cultural projects designed to forge a unified Mexican identity from the country’s fractured history.
The muralist movement was central to this project. Diego Rivera, David Alfaro Siqueiros, and Jose Clemente Orozco painted massive murals on the walls of government buildings throughout the city — in the National Palace, the Palace of Fine Arts, the Ministry of Education, and elsewhere. These murals told the story of Mexico from its pre-Hispanic roots through the conquest, colonial period, and revolution, celebrating indigenous heritage and working-class struggle. They remain some of Mexico City’s greatest artistic treasures.
The city began growing rapidly. UNAM (the National Autonomous University of Mexico) moved to its new campus in the south of the city in the early 1950s, with buildings designed by some of Mexico’s greatest architects and decorated with murals and mosaics. The campus is now a UNESCO World Heritage Site.
The Institutional Revolutionary Party (PRI) consolidated power and would rule Mexico without interruption for 71 years (1929-2000). Mexico City’s population exploded: from about 1 million in 1930 to 3 million by 1950 to over 5 million by 1960. Rural migrants poured into the capital, and the city sprawled outward in all directions, swallowing surrounding towns and villages.
1968: Olympics and Massacre
Mexico City was chosen to host the 1968 Summer Olympics — the first Latin American city to do so. The government invested heavily in new sports facilities, hotels, and infrastructure. The city was supposed to showcase modern Mexico to the world.
Instead, 1968 became synonymous with tragedy. Throughout the summer, university students had been protesting the authoritarian PRI government, demanding democratic reforms, freedom of political prisoners, and an end to police brutality. The student movement drew broad support from workers, families, and neighborhoods across the city. There was no single leader — it was a grassroots democratic movement that terrified a government accustomed to total control.
On October 2, 1968 — ten days before the Olympics were scheduled to begin — roughly 10,000 students and supporters gathered for a peaceful rally in the Plaza de las Tres Culturas in the Tlatelolco neighborhood. As the sun went down, army troops and a secret government unit called the Olympia Battalion surrounded the plaza. Helicopters dropped flares. Then the shooting started.
The government claimed soldiers had been fired upon first. Subsequent investigations and declassified documents revealed that government snipers in surrounding buildings had opened fire to provoke the confrontation. The army then fired into the crowd. The exact death toll has never been established: government sources initially acknowledged around 30, but eyewitnesses and later investigations suggest the number was in the hundreds. Over 1,300 people were arrested.
President Gustavo Diaz Ordaz had ordered the crackdown to ensure the Olympics went off smoothly. They did — the games opened on schedule ten days later. But the Tlatelolco massacre left a wound in Mexico’s national psyche that has never fully healed. October 2 is now commemorated annually, and the phrase “2 de octubre no se olvida” (October 2 is not forgotten) remains a rallying cry for Mexican social movements.
The 1985 Earthquake: Destruction and Rebirth
At 7:17 AM on September 19, 1985, an earthquake measuring 8.0 on the moment magnitude scale struck off the Pacific coast of Michoacan, more than 350 kilometers from Mexico City. Despite the distance, the city was devastated.
The reason goes back to the Aztecs and the lake. Mexico City’s Historic Center sits on the soft clay sediments of the old lakebed — the same lakebed where Tenochtitlan once stood. These sediments amplify seismic waves like a bowl of gelatin on a shaking table. Buildings between six and fifteen stories tall were particularly vulnerable because their natural vibration frequency matched the lakebed’s resonance of one cycle every 2.5 seconds. They essentially acted as tuning forks, shaking themselves apart.
The destruction was staggering: 412 buildings collapsed entirely and another 3,124 were severely damaged. Entire apartment buildings pancaked, with upper floors crushing lower ones. The official death toll was around 5,000, though many believe the actual number was closer to 10,000 or higher. Damage was estimated at three to five billion dollars.
President Miguel de la Madrid and the PRI government were widely criticized for their sluggish, incompetent response — including an initial refusal of foreign aid. It was ordinary citizens who organized rescue teams, set up shelters, distributed food, and dug through rubble with their bare hands. The earthquake became a watershed moment for Mexican civil society. People who had never organized before formed neighborhood associations, advocacy groups, and political movements. Many historians see the 1985 earthquake as the beginning of the end of the PRI’s authoritarian grip on power.
A major aftershock of magnitude 7.5 struck the very next day, September 20, causing additional damage and further terrorizing a traumatized city. Remarkably, most colonial-era buildings in the Historic Center survived — they were too short to resonate with the lakebed’s frequency. The Metropolitan Cathedral, built over four centuries on the soft lakebed, sustained damage but remained standing, as it had for hundreds of years.
Late 20th Century: Sprawl, Smog, and Change (1985-2000)
The earthquake accelerated changes that were already underway. Mexico City’s population continued to grow explosively — reaching roughly 15 million in the metropolitan area by 1990 — as rural poverty and lack of opportunity drove migration to the capital. Vast informal settlements (colonias populares) spread across the periphery, often lacking basic services like running water, sewage, and paved roads.
The environmental crisis reached alarming levels. Mexico City in the late 1980s and early 1990s had some of the worst air pollution on the planet. The city sits in a valley ringed by mountains that trap pollutants, and millions of vehicles, factories, and cooking fires pumped toxins into the air. Birds reportedly fell dead from the sky. The government implemented the Hoy No Circula program in 1989, restricting vehicles from driving one day per week based on their license plate numbers — a program that still exists today, though its effectiveness has been debated.
NAFTA (the North American Free Trade Agreement) took effect on January 1, 1994 — the same day the Zapatista uprising erupted in Chiapas. Mexico City’s economy was increasingly integrated with the United States, and the city attracted foreign investment and multinational corporations. But economic crises in 1994-95 (the “Tequila Crisis”) reminded everyone how fragile prosperity could be.
In 1997, Mexico City got its first elected head of government — previously, the president had appointed the city’s leader. Cuauhtemoc Cardenas, son of beloved former president Lazaro Cardenas, won the election for the center-left PRD party. It was a milestone for democracy in a city that had been governed by presidential fiat for over a century.
Then, in 2000, the PRI lost the presidency for the first time in 71 years when Vicente Fox of the PAN party won the national election. Mexico’s democratic transition was underway, and Mexico City — which consistently voted to the left of the rest of the country — was at its forefront.
The 21st Century: Renewal and Reinvention
The Mexico City of the 2000s and 2010s underwent a remarkable transformation. The deteriorating Historic Center, which had been in decline for decades as the wealthy moved to the western suburbs, became the focus of a major revitalization effort. Billionaire Carlos Slim — whose business empire was headquartered on the Zocalo — invested heavily in buying and restoring colonial buildings, creating pedestrian streets, and improving public spaces. The government followed with infrastructure improvements, cultural programming, and incentives for businesses and residents to return to the center.
Condesa and Roma Norte — the elegant Porfiriato-era neighborhoods that had fallen into neglect after the 1985 earthquake — were rediscovered by artists, young professionals, and restaurateurs in the late 1990s and 2000s. They became the city’s trendiest neighborhoods, packed with cafes, galleries, and some of Mexico’s best restaurants. What had been affordable, slightly rundown neighborhoods became destinations in their own right.
The National Anthropology Museum in Chapultepec Park — already one of the world’s greatest museums since its opening in 1964 — continued to draw visitors with its extraordinary collection of pre-Hispanic artifacts, including the Aztec Sun Stone and reconstructed Mayan temples. For anyone trying to understand Mexico City’s deep history, it’s an essential stop.
In 2016, the Mexican government initiated a process of greater autonomy for the capital, officially renaming it Ciudad de Mexico (CDMX) and giving it a status more like a state than a federal district. The city got its own constitution in 2017, a milestone in its long journey toward self-governance.
On September 19, 2017 — exactly 32 years to the day after the devastating 1985 earthquake — another major earthquake struck, this time a 7.1 magnitude centered in Puebla state. The coincidence was eerie enough to feel almost cruel. Over 200 buildings collapsed in the city, and at least 228 people died in the capital (369 total across Mexico). But the response was dramatically different from 1985: citizens mobilized within minutes, social media coordinated rescue efforts, and the government’s response, while imperfect, was far more competent. The city had learned from its past — literally building codes adopted after 1985 had saved countless structures and lives.
Mexico City Today: Living with History
Modern Mexico City is a metropolis of roughly 9.2 million people within city limits and over 22 million in the greater metropolitan area. It’s the largest city in North America, the oldest capital in the Americas, and one of the most culturally significant cities on the planet.
It’s also a city that can’t escape its own history — and doesn’t particularly want to. Walk through the Historic Center and you’ll see Aztec ruins next to colonial churches next to Art Nouveau mansions next to modern office buildings. The Metropolitan Cathedral is visibly sinking into the soft clay of the old lakebed — the same lakebed that was once Lake Texcoco. The entire city sinks an average of about 20 centimeters per year in some areas, a consequence of extracting groundwater from the aquifer beneath the old lake sediments.
Water remains the central challenge, just as it was for the Aztecs and the Spanish. But now the problem is inverted: instead of too much water (flooding), the city faces too little (scarcity). Mexico City imports a significant portion of its water from distant river systems, and the aquifer is being depleted faster than it recharges. Climate change is making droughts more severe. It’s a slow-motion crisis with deep historical roots — a direct consequence of decisions made centuries ago to drain the lakes.
Traffic, air pollution (much improved from the 1990s but still serious), inequality, housing costs, and public safety remain ongoing challenges. But the city is also more dynamic, more culturally confident, and more internationally connected than at any point in its history. Its restaurant scene is world-class. Its art and music scenes are thriving. Its neighborhoods each have distinct personalities shaped by the specific moment in history when they were built — from the 16th-century grid of the Historic Center to the Porfiriato elegance of Roma and Condesa to the modernist ambitions of mid-20th-century developments.
Seven hundred years after the Mexica spotted an eagle on a cactus and decided to build on a swampy island, their city is still here — transformed beyond anything they could have imagined, but still wrestling with the same fundamental challenges of water, space, and power that they faced. That continuity is what makes Mexico City’s history not just interesting but essential. The past isn’t buried here. It’s right under your feet, sinking a little more each year.
