The 1638 Tipu rebellion was a widespread revolt of Maya residents in the municipio or district of Bacalar in the second half of 1638. Led by Tipu, a pre-Columbian town and the most significant reducción or encomienda settlement in the district, it resulted in the removal of Bacalar and subsequent collapse of Spanish power in the region, leading to a 57-year revival of the Postclassic state of Dzuluinicob, of which Tipu had been capital.[note 1][note 2] Cite error: There are <ref group=note> tags on this page, but the references will not show without a {{reflist|group=note}} template (see the help page).
