After years of demanding greater political autonomy, residents were given the right to directly elect a Head of Government and the representatives of the unicameral Legislative Assembly by popular vote in 1997. Ever since, the left-wing Party of the Democratic Revolution (PRD) has controlled both of them. In recent years, the local government has passed a wave of liberal policies, such as abortion on request, a limited form of euthanasia, no-fault divorce, and same-sex marriage. On January 29, 2016, it ceased to be called the Federal District (Spanish: Distrito Federal or D.F.) and is now in transition to become the country's 32nd federal entity, giving it a level of autonomy comparable to that of a state. Because of a clause in the Mexican Constitution, however, as the seat of the powers of the Union, it can never become a state, lest the capital of the country be relocated elsewhere.

The city grew as the population did, coming up against the lake's waters. As the depth of the lake water fluctuated, Mexico City was subject to periodic flooding. A major labor draft, the desagüe, compelled thousands of Indians over the colonial period to work on infrastructure to prevent flooding. 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 Indian cultivation close to the capital.

Question: What was the labor draft called?
Answer: the desagüe

Question: Who helped build infrastructure around the lake?
Answer: Indians

Question: What was the main problem with being so close to the lake?
Answer: flooding

Question: What was a negative of regulating the lake's water height?
Answer: changed the habitat for fish and birds

The concept of nobility flourished in New Spain in a way not seen in other parts of the Americas. Spaniards encountered a society in which the concept of nobility mirrored that of their own. Spaniards respected the indigenous order of nobility and added to it. In the ensuing centuries, possession of a noble title in Mexico did not mean one exercised great political power, for one's power was limited even if the accumulation of wealth was not. The concept of nobility in Mexico 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 the last half of the 18th century. Many of these palaces can still be seen today, leading to Mexico City's nickname of "The city of palaces" given by Alexander Von Humboldt.

The Grito de Dolores ("Cry of Dolores") also known as El Grito de la Independencia ("Cry of Independence"), uttered from the small town of Dolores near Guanajuato on September 16, 1810, is the event that marks the beginning of the Mexican War of Independence and is the most important national holiday observed in Mexico. The "Grito" was the battle cry of the Mexican War of Independence by Miguel Hidalgo y Costilla, a Roman Catholic priest. Hidalgo and several criollos were involved in a planned revolt against the Spanish colonial government, and the plotters were betrayed. Fearing his arrest, Hidalgo commanded his brother Mauricio as well as Ignacio Allende and Mariano Abasolo to go with a number of other armed men to make the sheriff release the pro-independence inmates there on the night of September 15. They managed to set eighty free. Around 6:00 am September 16, 1810, Hidalgo ordered the church bells to be rung and gathered his congregation. Flanked by Allende and Juan Aldama, he addressed the people in front of his church, encouraging them to revolt. The Battle of Guanajuato, the first major engagement of the insurgency, occurred four days later. Mexico's independence from Spain was effectively declared in the Declaration of Independence of the Mexican Empire on September 27, 1821, after a decade of war. Unrest followed for the next several decades, as different factions fought for control of Mexico.

The Battle for Mexico City was the series of engagements from September 8 to September 15, 1847, in the general vicinity of Mexico City during the Mexican–American War. Included are major actions at the battles of Molino del Rey and Chapultepec, culminating with the fall of Mexico City. The U.S. Army under Winfield Scott scored a major success that ended the war. The American invasion into the Federal District was first resisted during the Battle of Churubusco on August 8 where the Saint Patrick's Battalion, which was composed primarily of Catholic Irish and German immigrants, but also Canadians, English, French, Italians, Poles, Scots, Spaniards, Swiss, and Mexican people, fought for the Mexican cause repelling the American attacks. After defeating the Saint Patrick's Battalion, the Mexican–American War came to a close after the United States deployed combat units deep into Mexico resulting in the capture of Mexico City and Veracruz by the U.S. Army's 1st, 2nd, 3rd and 4th Divisions.

During this era of Porfirian rule, the city underwent an extensive modernization. Many Spanish Colonial style buildings were destroyed, replaced by new much larger Porfirian institutions and many outlying rural zones were transformed into urban or industrialized districts with most having electrical, gas and sewage utilities by 1908. While the initial focus was on developing modern hospitals, schools, factories and massive public works, perhaps the most long-lasting effects of the Porfirian modernization were creation of the Colonia Roma area and the development of Reforma Avenue. Many of Mexico City's major attractions and landmarks were built during this era in this style.

Diaz's plans called for the entire city to eventually be modernized or rebuilt in the Porfirian/French style of the Colonia Roma; but the Mexican Revolution began soon afterward and the plans never came to fruition, with many projects being left half-completed. One of the best examples of this is the Monument to the Mexican Revolution. Originally the monument was to be the main dome of Diaz's new senate hall, but when the revolution erupted only the dome of the senate hall and its supporting pillars were completed, this was subsequently seen as a symbol by many Mexicans that the Porfirian era was over once and for all and as such, it was turned into a monument to victory over Diaz.

In 1980 half of all 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 shantytowns that extended for many miles. This caused serious air pollution in Mexico City and water pollution problems, as well as subsidence due to overextraction of groundwater. Air and water pollution has been contained and improved in several areas due to government programs, the renovation of vehicles and the modernization of public transportation.

Question: How many of the industrial jobs in the county were based in Mexico City in the late 20th century?
Answer: half

Question: What did the countryside workers make to live in?

Mexico City is located in the Valley of Mexico, sometimes called the Basin of Mexico. This valley is located in the Trans-Mexican Volcanic Belt in the high plateaus of south-central Mexico. It has a minimum altitude of 2,200 meters (7,200 feet) above sea level and is surrounded by mountains and volcanoes that reach elevations of over 5,000 metres (16,000 feet). This valley has no natural drainage outlet for the waters that flow from the mountainsides, making 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 here. 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 the over-extraction of groundwater, called groundwater-related subsidence. Since the beginning of the 20th century the city has sunk as much as nine metres (30 feet) in some areas. This sinking is causing problems with runoff and wastewater management, leading to flooding problems, especially during the rainy season. 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.

Question: When did draining of Lake Texcoco begin?
Answer: 17th century

The area receives about 820 millimetres (32.3 in) of annual rainfall, which is concentrated from June through September/October with little or no precipitation the remainder of the year. The area has two main seasons. The rainy season runs from June to October when winds bring in tropical moisture from the sea. The dry season runs from November to May, when the air is relatively drier. This dry season subdivides into a cold period and a warm period. The cold period spans from November to February when polar air masses push down from the north and keep the air fairly dry. The warm period extends from March to May when tropical winds again dominate but do not yet carry enough moisture for rain.

Originally much of the valley laid 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 the siege of Tenochtitlan, and during colonial times the Spanish regularly drained the lake to prevent floods. Only a small section of the original lake remains, located outside the Federal District, in the municipality of Atenco, State of Mexico.

By the 1990s Mexico City had become infamous as one of the world's most polluted cities; however the city has become a model for dramatically lowering pollution levels. By 2014 carbon monoxide pollution had dropped dramatically, while levels of sulfur dioxide and nitrogen dioxide were nearly three times lower than in 1992. The levels of signature pollutants in Mexico City are similar to those of Los Angeles.[citation needed] Despite the cleanup, the metropolitan area is still the most ozone-polluted part of the country, with ozone levels 2.5 times beyond WHO-defined safe limits.

To clean up pollution, the federal and local governments implemented numerous plans including the constant monitoring and reporting of environmental conditions, such as ozone and nitrogen oxides. When the levels of these two pollutants reached critical levels, contingency actions were implemented which included closing factories, changing school hours, and extending the A day without a car program to two days of the week. The government also instituted industrial technology improvements, a strict biannual vehicle emission inspection and the reformulation of gasoline and diesel fuels. The introduction of Metrobús bus rapid transit and the Ecobici bike-sharing were among efforts to encourage alternate, greener forms of transportation.

Due in large part to the persuasion of representative Servando Teresa de Mier, Mexico City was chosen because it was the center of the country's population and history, even though Querétaro was closer to the center geographically. The choice was official on November 18, 1824, and Congress delineated a surface area of two leagues square (8,800 acres) centered on the Zocalo. This area was then separated from the State of Mexico, forcing that state's government to move from the Palace of the Inquisition (now Museum of Mexican Medicine) in the city to Texcoco. This area did not include the population centers of the towns of Coyoacán, Xochimilco, Mexicaltzingo and Tlalpan, all of which remained as part of the State of Mexico.

In 1854 president Antonio López de Santa Anna enlarged the area of the Federal District almost eightfold from the original 220 to 1,700 km2 (80 to 660 sq mi), annexing the rural and mountainous areas to secure the strategic mountain passes to the south and southwest to protect the city in event of a foreign invasion. (The Mexican–American War had just been fought.) The last changes to the limits of the Federal District were made between 1898 and 1902, reducing the area to the current 1,479 km2 (571 sq mi) by adjusting the southern border with the state of Morelos. By that time, the total number of municipalities within the Federal District was twenty-two.
