Their migration may be part of a general movement of peoples that follows, or perhaps that helps trigger, the collapse of the Toltec civilization. They settle on islands in Lake Texcoco. The Aztec are skilled agriculturists who construct artificial island farms called chinampas and plant crops, such as maize (corn), beans, and squash. Their success in creating a great state and ultimately a powerful empire is due in part to their remarkable system of agriculture, which features intensive cultivation of all available land and elaborate systems of irrigation.

The Aztec establish the city of Tenochtitlán, which becomes the capital of the empire. Located at the site of what is now Mexico City, Mexico, Tenochtitlán is built on two islands in Lake Texcoco and is connected to the mainland by several causeways. Through the construction of artificial islands, Tenochtitlán grows to cover more than 5 square miles (13 square kilometers).

Spanish conquistadorHernán Cortés and about 500 soldiers and 100 sailors set sail from Cuba on February 18, 1519, with 11 ships. After rounding the Yucatán Peninsula, they arrive in March on the coast of what is now the Mexican state of Tabasco.

She becomes concubine, guide, and interpreter to Cortés during his subsequent conquest of Mexico.

Cortés leaves to combat a rival Spanish force on the coast, giving Pedro de Alvarado charge of the Aztec capital. Upon his return, Cortés finds the Spanish garrison in Tenochtitlán besieged by the Aztecs after Alvarado massacred many leading Aztec chiefs. Montezuma dies in Spanish custody. Cortés decides to retreat from the capital at night, but in doing so the Spanish suffer heavy casualties. After six days of retreat Cortés wins the battle of Otumba over the Aztecs sent in pursuit (July 7). Cuitláhuac becomes the next Aztec leader.
