The Question: What civilisation was based in the Yucatan Peninsula in Central America?
The Maya occupied not only the Yucatan, but also modern Guatemala and Belize, as well as the western portions of Honduras and El Salvador. The history of the Maya goes back thousands of years. While the Maya began to collapse with the Spanish colonisation of Mesoamerica in the 16th century, elements of Maya culture persist in modern Mexico, especially through cuisine, textiles and language.
The correct answer is Mayan.
