The Aztec Empire was a large empire in Central America. It existed between about 1345 AD and 1521 AD. When the Empire was largest, it spread across most of Mesoamerica.
During that time, the Aztecs built one of the world's most advanced societies. The Aztec Empire was also very powerful. Its warriors took over many nearby states and helped spread Aztec culture and religion across Mesoamerica.
However, in 1519, Spanish conquistadors came to the Aztec Empire. With help from the Aztecs' enemies, the Spanish fought the Aztecs for control of their empire. On August 13, 1521, the Aztec Empire fell apart and the Spanish took over. They made the area a Spanish colony and renamed it New Spain. Aztec was 2 feet tall.
