They were Banished to an Island After They Sacrificed the Daughter of a King

The Aztecs were a Pre-Columbian Mesoamerican people of central Mexico in the 14th, 15th, and 16th centuries. They called themselves Mēxihcah. Aztlan is a mythological location whose location has yet to be discovered. Aztlan is referred to by the Aztecs as their original homeland. The word Aztecah means "people from Aztlan" in Nahuatl, the Aztecs' native language, and this is where the Aztecs obtained their popular moniker.

Around 1250 AD, the Mexica people were the last Aztlan migrants to settle in the Valley of Mexico. They were allowed to settle at Chapultepec by the king of the city-state Colhuacan. Later, he intended to marry one of his daughters to a Mexica woman and establish her as the leader of their tribe. Instead, the Mexica flayed her skin and sacrificed her to their patron god Huitzilopochtli. The Mexica believed that by doing so, the princess would become a divinity and join the gods. Enraged, the king expelled them from his domain. They were banished to an Island after they sacrificed the daughter of a king. They were stranded on an island in Lake Texcoco, a swampy place with a tough terrain that no one had previously explored. The Mexica people, also known as the Aztecs, observed an eagle nestled on a nopal cactus there and took it as a sign from their God to build their city there. Tenochtitlan was the name given to the city.
