Aztec Environment. The Aztec livelihood began with the development surrounding their environment, for it provided nourishment from agricultural goods and guidance of seasonal changes for other cultural practices. The Aztec Empire was located in the central and southern regions of present day Mexico. As the Aztec Empire grew in the 15th and 16th centuries, it stretched from the Pacific Ocean to the Gulf of Mexico. The empire consisted of city states with three allied capitals in the Basin of Mexico.
The ancestors of the Aztecs settled on a marshy island in Lake Texcoco in either 1325 or 1345. According to legend the Aztecs settled at a place where they saw an eagle perched on a cactus with a snake in its mouth. They took this as a sign from their god that they should settle there.he Aztecs called the place Tenochtitlan, which means place of the cactus. At first they were an unimportant people but in the 15th century the Aztecs gradually built up a large empire. However the Aztec empire was not an 'empire' like the Roman Empire, which was ruled from one city.
