Codex Huamantla, which is also called the Codex of Huamantla and Códice de Huamantla is a book about the Otomi people. It was made by two people. People think it was finished in the year 1592. The first story is about the Otomi people migrating from a place called Chiapas to another place called Huamantla, Tlaxcala, which are both in the country of Mexico today. The other story is about how the Otomi people were involved in the Spanish conquest of the Aztec Empire.[1][2]
