Mexico City is the oldest capital city in the Americas and one of two founded by Indigenous people. The city was originally built on a group of islands in Lake Texcoco by the Mexica around 1325, under the name Tenochtitlan. It was almost completely destroyed in the 1521 siege of Tenochtitlan and subsequently redesigned and rebuilt in accordance with the Spanish urban standards. In 1524, the municipality of Mexico City was established, known as , and as of 1585, it was officially known as (Mexico City). Mexico City played a major role in the Spanish colonial empire as a political, administrative, and financial center. Following independence from Spain, the federal district was established in 1824.

After years of demanding greater political autonomy, residents were finally given 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. The city has several progressive policies, such as elective abortions, a limited form of euthanasia, no-fault divorce, same-sex marriage, and legal gender change. On 29 January 2016, it ceased to be the ''Federal District'' ( or ) and is now officially known as (or ), with a greater degree of autonomy. A clause in the Constitution of Mexico, however, prevents it from becoming a state within the Mexican federation, as long it remains the capital of the country. Provided by Wikipedia
