The crowds of laborers were so numerous that one could hardly move in the streets and causeways, although they are very wide. Many died from being crushed by beams, or falling from high places, or in tearing down old buildings for new ones. Preconquest Tenochtitlan

2889-486: The city proper was 9,209,944, with a land area of 1,495 square kilometers (577 sq mi). According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21,804,515, which makes it the sixth-largest metropolitan area in the world, the second-largest urban agglomeration in the Western Hemisphere (behind São Paulo , Brazil ), and

2996-566: The massacre of an unknown number of protesting students in Tlatelolco . Three years later, a demonstration in the Maestros avenue, organized by former members of the 1968 student movement, was violently repressed by a paramilitary group called " Los Halcones ", composed of gang members and teenagers from many sports clubs who received training in the US.

3103-532: The 1768 naval expedition of Pyotr Krenitsyn and Mikhail Levashov alarmed the Spanish government and served to justify Gálvez's vision. The Portolá expedition was the first European land-entry expedition into the area that is now California. The missionaries and soldiers encountered numerous Indigenous peoples of the area , who became the primary subjects of the expanding Jesuit and Franciscan missions that were already established in Baja California and Baja California Sur . The expedition first established

3210-460: The 1769 Portola expedition first established a military/civil government, and the local political structures were unchanged. The friction came to a head in 1836, when Monterey-born Juan Bautista Alvarado led a revolt against the 1836 constitution, seizing control of Monterey from Nicolás Gutiérrez . Alvarado's actions nearly led to a civil war with loyalist forces based in Los Angeles, but

4494-481: The Spanish preserved Tenochtitlan's basic layout, they built Catholic churches over the old Aztec temples and claimed the imperial palaces for themselves. Tenochtitlan was renamed "Mexico" because the Spanish found the word easier to pronounce. The city had been the capital of the Aztec Empire and in the colonial era, Mexico City became the capital of New Spain . The viceroy of Mexico or vice-king lived in

Alta California Alta California ('Upper California'), also known as Nueva California ('New California') among other names, was a province of New Spain formally established in 1804. Along with

4708-630: The U.S. military occupation began. In the final decades of Mexican rule, American and European immigrants arrived and settled in the former Alta California. Those in Southern California mainly settled in and around the established coastal settlements and tended to intermarry with the Californios. In Northern California, they mainly formed new settlements further inland, especially in the Sacramento Valley , and these immigrants focused on fur-trapping and farming and kept apart from

4815-425: The United States and Spain, established the northern limit of Alta California at latitude 42°N, which remains the boundary between the states of California, Nevada and Utah (to the south) and Oregon and Idaho (to the north) to this day.

4922-543: The age of two. The precolonial Indigenous population of California is estimated to have numbered around 340,000 people, who were diverse culturally and linguistically. From 1769–1832, at least 87,787 baptisms and 63,789 deaths of Indigenous peoples occurred, demonstrating the immense death rate at the missions in Alta California. Conversion to Christianity at the colonial missions was often resisted by Indigenous peoples in Alta California. Many missionaries in

5029-479: The area closest to the main square in what was known as the traza , in orderly, well laid-out streets. Indigenous residences were outside that exclusive zone and houses were haphazardly located. Spaniards sought to keep indigenous people separate but since the Zócalo was a center of commerce for Amerindians, they were a constant presence in the central area, so strict segregation was never enforced. At intervals Zócalo

5136-446: The area was struck by the 1985 Mexico City earthquake . The earthquake proved to be a disaster politically for the one-party state government. The Mexican government was paralyzed by its own bureaucracy and corruption, forcing ordinary citizens to create and direct their own rescue efforts and to reconstruct much of the housing that was lost as well. However, the last straw may have been the controversial elections of 1988. That year,

5243-451: The armies of Pancho Villa and Emiliano Zapata , but the city did not experience violence. Huerta had abandoned the capital and the conquering armies marched in. Venustiano Carranza 's Constitutionalist faction ultimately prevailed in the revolutionary civil war and Carranza took up residence in the presidential palace. In the 20th century the phenomenal growth of the city and its environmental and political consequences dominate. In 1900,

5564-501: The camaraderie did not last long. Cortés put Moctezuma under house arrest , hoping to rule through him. Tensions increased until, on the night of 30 June 1520 – during a struggle known as " La Noche Triste " – the Aztecs rose up against the Spanish intrusion and managed to capture or drive out the Europeans and their Tlaxcalan allies. Cortés regrouped at Tlaxcala. The Aztecs thought the Spaniards were permanently gone, and they elected

5671-445: The capital. The 16th century saw a proliferation of churches, many of which can still be seen today in the historic center . Economically, Mexico City prospered as a result of trade. Unlike Brazil or Peru , Mexico had easy contact with both the Atlantic and Pacific worlds. Although the Spanish crown tried to completely regulate all commerce in the city, it had only partial success. The concept of nobility flourished in New Spain in

5778-574: The central government without much consideration of local conditions, such as the Mexican secularization act of 1833 , causing friction between governors and the people. In 1836, Mexico repealed the 1824 federalist constitution and adopted a more centralist political organization (under the " Seven Laws ") that reunited Alta and Baja California in a single California Department ( Departamento de las Californias ). The change, however, had little practical effect in far-off Alta California. The capital of Alta California remained Monterey, as it had been since

5885-413: The city vulnerable to flooding. Drainage was engineered through the use of canals and tunnels starting in the 17th century. Mexico City primarily rests on what was Lake Texcoco . Seismic activity is frequent there. Lake Texcoco was drained starting from the 17th century. Although none of the lake waters remain, the city rests on the lake bed's heavily saturated clay. This soft base is collapsing due to

Floods were not only an inconvenience but also a health hazard, since during flood periods human waste polluted the city's streets. By draining the area, the mosquito population dropped as did the frequency of the diseases they spread. However, draining the wetlands also changed the habitat for fish and birds and the areas accessible for indigenous cultivation close to

6206-439: The construction of large sporting facilities. In 1969, the Mexico City Metro was inaugurated. Explosive growth in the population of the city started in the 1960s, with the population overflowing the boundaries of the Federal District into the neighboring State of Mexico, especially to the north, northwest, and northeast. Between 1960 and 1980 the city's population more than doubled to nearly 9 million. In 1980, half of all

He did not establish a territory under his own personal rule , but remained loyal to the Spanish crown. The first Spanish viceroy arrived in Mexico City fourteen years later. By that time, the city had again become a city-state , having power that extended far beyond its borders. Although

Snow falls in the city scarcely, although somewhat more often on nearby mountaintops. Throughout its history, the Central Valley of Mexico was accustomed to having several snowfalls per decade (including a period between 1878 and 1895 in which every single year—except 1880—recorded snowfalls ), mostly lake-effect snow . The effects of

7062-610: The industrial jobs in Mexico were located in Mexico City. Under relentless growth, the Mexico City government could barely keep up with services. Villagers from the countryside who continued to pour into the city to escape poverty only compounded the city's problems. With no housing available, they took over lands surrounding the city, creating huge shanty towns . The inhabitants of Mexico City faced serious air pollution and water pollution problems, as well as groundwater-related subsidence . Air and water pollution has been contained and improved in several areas due to government programs,

The cool sunny winter runs from November to April, when

7918-630: The missions until they were secularized, beginning in 1833. The transfer of property never occurred under the Franciscans. As the number of Spanish settlers grew in Alta California, the boundaries and natural resources of the mission properties became disputed. Conflicts between the Crown and the Church arose over land. State and ecclesiastical bureaucrats debated over authority of the missions. The Franciscan priests of Mission Santa Clara de Asís sent

8025-621: The northern port cities of Monterey and San Francisco. The forces of the California Republic, upon encountering the United States Navy and, from them, learning of the state of war between Mexico and the United States, abandoned their independence and proceeded to assist the United States forces in securing the remainder of Alta California. The California Republic was never recognized by any nation and existed for less than one month, but its flag (the "Bear Flag") survives as

8132-455: The old Aztec ceremonial center. The existing central plaza of the Aztecs was effectively and permanently transformed to the ceremonial center and seat of power during the colonial period, and remains to this day in modern Mexico, the central plaza of the nation.

8239-640: The original 113,009 acre Rancho Simí grant, but sometime around 1820-1830, the Rancho Tapo came to be thought of as a separate place within Rancho Simí. The last of the De la Guerras to live in Simí Valley retreated to a 14,400-acre portion of the original rancho that was known as the Tapo Rancho. As late as February 1877, Juan De la Guerra was reported in county newspapers to be preparing to plant walnuts in

8346-419: The over-extraction of groundwater, called groundwater-related subsidence . Since the beginning of the 20th century the city has sunk as much as nine meters (30 feet) in some areas. On average Mexico City sinks 20 inches (1 foot and 8 inches) or 50 centimetres (1/2 meters ) every year. This sinking is causing problems with runoff and wastewater management, leading to flooding problems, especially during

It was the imperial capital on two occasions (1821–1823 and 1864–1867), and of two federalist states and two centralist states that followed innumerable coups d'états in the space of half a century before the triumph of the Liberals after the Reform War . It was also the objective of one of the two French invasions to Mexico ( 1861–1867 ), and occupied for

8667-568: The population of Mexico City was about 500,000. The city began to grow rapidly westward in the early part of the 20th century and then began to grow upwards in the 1950s, with the Torre Latinoamericana becoming the city's first skyscraper. The rapid development of Mexico City as a center for modernist architecture was most fully manifested in the mid-1950s construction of the Ciudad Universitaria, Mexico City ,

8774-636: The postal abbreviation of the Federal District in Spanish: D.F., which is read "De-Efe"). They are formally called capitalinos (in reference to the city being the capital of the country), but "[p]erhaps because capitalino is the more polite, specific, and correct word, it is almost never utilized". The oldest signs of human occupation in the area of Mexico City are those of the " Peñón woman " and others found in San Bartolo Atepehuacan ( Gustavo A. Madero ). They were believed to correspond to

8881-432: The presidency was set between the P.R.I. 's candidate, Carlos Salinas de Gortari, and a coalition of left-wing parties led by Cuauhtémoc Cárdenas , son of the former president Lázaro Cárdenas . The counting system "fell" because coincidentally the power went out and suddenly, when it returned, the winning candidate was Salinas, even though Cárdenas had the upper hand. As a result of the fraudulent election, Cárdenas became

8988-596: The province wrote of their frustrations with teaching Indigenous people to internalize Catholic scripture and practice. Many Indigenous people learned to navigate religious expectations at the missions with complex social behaviors in order to maintain their cultural and religious practices. In 1784, the Spanish established the first rancho, Rancho San Pedro , as a 48,000 acre site for cattle grazing . Nine ranchos were subsequently established before 1800. Spanish, and later Mexican, governments rewarded retired soldados de cuera with large land grants, known as ranchos , for

9095-461: The raising of cattle and sheep . Hides and tallow from the livestock were the primary exports of California until the mid-19th century. Similar to the missions, the construction, ranching and domestic work on these vast estates was primarily done by Indigenous peoples , who learned to speak Spanish and ride horses. Under Spanish and Mexican rule, the ranchos prospered and grew. Rancheros (cattle ranchers) and pobladores (townspeople) evolved into

9202-565: The recently re-discovered Los Pobladores . Mission San Juan Capistrano was founded at the Acjachemen village of Acjacheme . Mission San Fernando was founded at Achooykomenga . As the Spanish and civilian settlers further intruded into Indigenous lands and imposed their practices, ideas of property, and religion onto them backed by the force of soldiers and settlers, Indigenous peoples formed rebellions on Spanish missions and settlements. A major rebellion at Mission San Gabriel in 1785

9309-472: The renovation of vehicles and the modernization of public transportation. The autocratic government that ruled Mexico City since the Revolution was tolerated, mostly because of the continued economic expansion since World War II. This was the case even though this government could not handle the population and pollution problems adequately. Nevertheless, discontent and protests began in the 1960s leading to

9416-593: The right to elect both a head of government and the representatives of the unicameral Legislative Assembly by election in 1997. Ever since, left-wing parties (first the Party of the Democratic Revolution and later the National Regeneration Movement ) have controlled both of them.

Texcoco de Mora and then Toluca became the capital of the State of Mexico. During the 19th century, Mexico City was the center stage of all

9844-622: The southerly currents of the distant northwestern Pacific. Ultimately, New Spain did not have the economic resources nor population to settle such a far northern outpost. Spanish interest in colonizing Alta California was revived under the visita of José de Gálvez as part of his plans to completely reorganize the governance of the Interior Provinces and push Spanish settlement further north. In subsequent decades, news of Russian colonization and maritime fur trading in Alaska, and

9951-462: The summer. The entire lake bed is now paved over and most of the city's remaining forested areas lie in the southern boroughs of Milpa Alta , Tlalpan and Xochimilco . Originally much of the valley lay beneath the waters of Lake Texcoco , a system of interconnected salt and freshwater lakes. The Aztecs built dikes to separate the fresh water used to raise crops in chinampas and to prevent recurrent floods. These dikes were destroyed during

10058-417: The total draining of what was left of Lake Texcoco. After the disappearance of Lake Texcoco, snow has never fallen again over Mexico City. The region of the Valley of Mexico receives anti-cyclonic systems.

10272-504: The unique Californio culture. By law, mission land and property were to pass to the Indigenous population after a period of about ten years, when the Indigenous people would become Spanish subjects. In the interim period, the Franciscans were to act as mission administrators who held the land in trust for the Indigenous residents. The Franciscans, however, prolonged their control over the missions even after control of Alta California passed from Spain to independent Mexico, and continued to run

10379-488: The viceregal palace on the main square or Zócalo . The Mexico City Metropolitan Cathedral , the seat of the Archbishopric of New Spain, was constructed on another side of the Zócalo, as was the archbishop's palace, and across from it the building housing the city council or ayuntamiento of the city.

In 1850, California joined

10593-423: Was built in the center of the inland lake system, with the city reachable by canoe and by wide causeways to the mainland. The causeways were rebuilt under Spanish rule with indigenous labor. Colonial Spanish cities were constructed on a grid pattern, if no geographical obstacle prevented it.

Many children died young at the missions. One missionary reported that 3 of every 4 children born at Mission San Gabriel died before reaching

10914-418: Was not political but rather a very conservative Spanish social one, based on proving the worthiness of the family. Most of these families proved their worth by making fortunes in New Spain outside of the city itself, then spending the revenues in the capital, building churches, supporting charities and building extravagant palatial homes. The craze to build the most opulent residence possible reached its height in

11021-404: Was patented to José de la Guerra y Noriega in 1865. José de la Guerra y Noriega 's death in 1858, his sons continued to operate the ranchos. The end of their prosperity came when several years of drought in the 1860s caused heavy losses.
