Tzucacab is a town and the municipal seat of the Tzucacab Municipality in Yucatán, Mexico. It gained prominence for being the site where the Treaty of Tzucacab was signed, an attempt to end the brutal Caste War of Yucatán that began in the Yucatán Peninsula in 1847. This conflict persisted until 1901 when Mexican federal troops finally reclaimed the last strongholds from indigenous Maya rebels, specifically Bacalar and Chan Santa Cruz in what is now the state of Quintana Roo.
