The Spanish Conquest of Yucatán was the campaign undertaken by the Spanish "conquistadores" against the Late Postclassic Maya states. This part of the conquest and colonization of the Americas began in the early 16th century, but it took more time than the similar campaigns against the Aztec and Inca Empires. It was about 170 years later before the last Maya stronghold fell, that of the Itza capital of Tayasal on Lake Petén Itzá, in 1697. But except for the Petén region and the Guatemalan highlands, the Spanish had control over Yucatán itself already by 1546.
