The Aztec Empire, was a very powerful Empire. They were also highly skilled engineers, which led them to build the Floating Gardens. The Human sacrifices of Aztec was a part of their religious ceremony that they believed properly appeased their gods to spare them from suffering. To use the hilly land for farming, the Aztecs terraced the hills by cutting into them. They then built a restraining wall to form a step in the hillside so that the land on the step can be used for crops. To bring water to these fields, Aztecs farmers dug irrigation canals in the soil.
