Inca Roca (Quechua Inka Roq'a, "magnanimous Inca") was the sixth Sapa Inca of the Kingdom of Cusco (beginning around CE 1350) and the first of the Hanan ("upper") Qusqu dynasty. After Cápac Yupanquiʻs death, the hanan moiety rebelled against the hurin, killed Quispe Yupanqui, and gave the throne to Inca Roca, son of another of Cápac Yupanquiʻs wives, Cusi Chimbo. Inca Roca moved his palace into the hurin section of Cuzco. In legend, he is said to have conquered the Chancas (among other peoples), as well as established the yachaywasi, schools for teaching nobles. More soberly, he seems to have improved the irrigation works of Cuzco and neighboring areas, but the Chancas continued to trouble his successors. (He creates yachaiwasis or schools for the nobles. Under his reign he establishes friendly ties with nearby tribes).
