The Distrito Federal, or Mexico City as it is called in English, has no comparison when it comes to other cities in Mexico. It is truly the capital in every sense of the word. With over 20 million people, it is not only many times larger than any other city in Mexico, but also the second most populous city in the world, just behind Tokyo.
Mexico is bordered by the United States to the north and Belize and Guatemala to the southeast. Mexico is about one-fifth the size of the United States. Baja California in the west is an 800-mile (1,287-km) peninsula that forms the Gulf of California. In the east are the Gulf of Mexico and the Bay of Campeche, which is formed by Mexico's other peninsula, the Yucatán. The center of Mexico is a great, high plateau, open to the north, with mountain chains on the east and west and with ocean-front lowlands beyond.
There has been a capital here since before the arrival of the Spanish. Unfortunately, virtually all of the old Aztec city of Tenoctitlan was destroyed by the Spanish in their zeal to convert the Indians toChristianity and erasetheir past. One impressive remain, however, El Templo Mayor, still survives. This is what's left of the Great Temple of the Aztecs. The ruin sits off the northeast corner of the Zocalo, the city's massive main square.
Mexico City wasn’t always your typical urban monstro-city it is today. At some point in time, before the name Mexico City was even coined, what it is today Mexico City used to be a breathable fresh-aired valley surrounded by vegetation, exotic animals, an impressive volcano with a snow cap during winters, and just in the middle of the valley, there was a huge lake just about the same size as the Great Lakes of Michigan. Along came man and saw this marvel of nature and fell in love with it. Man, or more plurally correct, men of the Aztec Empire, which ruled the western hemisphere at the time, named this lake after their God of Water, Tenochtitlan. El Niño de Tocha, which means “the child of Tocha”--no one knows what Tocha means-- who was Emperor of the Aztecs at the time thought Lake Tenochtitlan was a waste of land and gave an order that changed the history of the Democratic Republic of the United States of Mexicans, as we known it. The water of Lake Tenochtitlan was pumped out and the dried lake was later filled in with fresh soil.
