The Aztecs were formed after the Toltec people occurred when hundreds of civilians came towards Lake texcoco. Late families were unfortunate and were forced to go to the swamp lands. In the swamp lands there was only one piece of land to farm on and it was totally surrounded by more marshes . The Aztec families some how converted these disadvantages to a might empire known as they Aztec Empire. People say the empire was partially formed by a deeply believed legend. As the the legend went it said that Aztec people would create a empire on in a swampy place where they would see an eagle eating a snake while perched on a cactus which is growing out of a rock in the swamplands. This is what priests claimed they saw while entering the new land.
