Spanish conquest of Yucatán
The Spanish conquest of Yucatán was the campaign undertaken by the Spanish conquistadores against the Late Postclassic Maya states and polities in the Yucatán Peninsula, a vast limestone plain covering south-eastern Mexico, northern Guatemala, and all of Belize. The Spanish conquest of the Yucatán Peninsula was hindered by its politically fragmented state.
