The Muisca were the Chibcha-speaking people that formed the Muiscan Confederation of the central highlands of present-day Colombia's Eastern Range. They were encountered by the Spanish Empire in 1537, at the time of the conquest. Subgroupings of the Muisca were mostly identified by their allegiances to three great rulers: the Zaque, centered in Chunza, ruling a territory roughly covering modern southern and northeastern Boyacá and southern Santander; the Zipa, centered in Bacatá, that territory emcompassing most of modern Cundinamarca, the western Llanos and northeastern Tolima; and the Iraca, ruler of Suamox and modern northeastern Boyacá and southwestern Santander.
The territory of the Muisca spanned an area of around 47,000 square kilometres (18,000 sq mi) (a region slightly larger than Switzerland) from the north of Boyacá to the Sumapaz Páramo and from the summits of the Eastern Range to the Magdalena Valley. It bordered the territories of the Panches and Pijaos tribes.
At the time of the conquest, the area had a large population, although the precise number of inhabitants is not known. The languages of the Muisca were dialects of Chibcha, also called Muysca and Mosca, which belong to the Chibchan language family. The economy was based on agriculture, metalworking and manufacturing.
