The Muisca were a pre-Columbian culture and colonial communities of the Altiplano Cundiboyacense before the Spanish colonization of the Americas, whose customs lasted up to the beginning of the 19th century and Colombian independence, and are indigenous peoples in Colombia in a process of cultural re-definition and revitalization. The Muisca spoke Muysccubun, a language of the Chibchan language family, also called Muysca and Mosca, which is part of an important revival effort. The first known contact with Europeans in the region was in 1537 during the Spanish conquest of New Granada.
