USA HISTORY

Detailed explanation-1: -The Aztec built their capital city, Tenochtitlan, on Lake Texcoco. Built on two islands, the area was extended using chinampas-small, artificial islands created above the waterline that were later consolidated. Tenochtitlan eventually reached an area of more than 13 square kilometers (five square miles).

Detailed explanation-2: -Comprised of raised fields, chinampas provided enough fertile soil into which the Aztecs could plant seeds and grow enough sustenance for the people in the empire. The natural land of the region was not fertile nor solidified enough to do so. The Aztecs would dredge canals and place the layers of mud to the sides.

Detailed explanation-3: -The Aztecs expanded their empire through military conquest and sustained it through tributes imposed on the conquered regions. Every 80 days, the new subjects of the Aztecs had to pay tributes to Tenochtitlan. As for the Aztec society, it was very complex. It was socially divided between the nobility and the populace.

Detailed explanation-4: -Their relatively sophisticated system of agriculture (including intensive cultivation of land and irrigation methods) and a powerful military tradition would enable the Aztecs to build a successful state, and later an empire.
