In the centuries before the arrival of the Spanish conquistadors, the central highlands of Colombia consisted of the Muisca Confederation, ruled by "zaques" from Hunza and "zipas" from Bacatá. Other areas, such as the territories surrounding Sogamoso were ruled by "caciques"; respected religious nobility. Before the time of the first confirmed human rulers Hunzahúa, who is considered an heir of Idacansás, and Meicuchuca, inaugurated in 1450, the chronicles are based on mythology.
