Organized religion was very popular in the 3 groups, but mostly the Aztec. The Aztec had a ton of religious practices. The Aztec believed that there was 4 worlds before them, and 4 suns. They believed that they were on their fifth and final sun, and in order to keep the sun alive, they would have to sacrafice people. They had the most sacrafice out of all of the groups, and were polytheistic. Sacrafice was critical to keep their crops growing, and the world going. They also did sacrafice to make the gods happy. They thought that the world was going to end in 2011, when the Maya thought the world would end on December 21, 2012. The Aztec had over 1,000 gods! The god of war was Huitzilopochitli, and he sent Mesrlika on the journey to Aztlan. Tlaloc was the rain god, and Templo Mayor was built for the gods. The Aztec may of had a lot of organized religion, but they did have a purpose to do it.
