The Muisca was the Chibcha-speaking people that formed the Muisca Confederation in the central highlands of present-day Colombia. They were encountered by the troops of Gonzalo Jiménez de Quesada, in name of the Spanish Empire at the time of the conquest in the spring of 1537. The Muisca comprised two confederations: Hunza (present-day Tunja) was located in the northern area, whose sovereign was the "zaque"; and Bacatá the southern area, whose sovereign was the "zipa". Both confederations were located in the highlands of modern-day Cundinamarca and Boyacá ("Altiplano Cundiboyacense") in the central area of Colombia's Eastern Ranges.
