The Yucatán Peninsula's east coastline held an ancient Mayan city of Tulum. The city served as the headquarters of the Caribbean Assassins until 1722, when they relocated to Great Inagua in the Bahamas.
The pirate Edward Kenway ventured to the peninsula in 1719. After ending a quick meeting with Bartholomew Roberts, Kenway discovered the Templar Benjamin Hornigold had been following him. Edward disabled Hornigold's ship, evaded his crew and eliminated Benjamin in Santanillas.
In 1751, Templar Rafael Joaquín de Ferrer discovered two First Civilization Temples under the Mayan city of Chichen Itza. The Templars established a colony and began to dig the place in search of the Prophecy Disks. In 1769 and 1772, the Assassin Aveline de Grandpré visited Chichen Itza and recovered the two halves of the Prophecy Disk.
