The ruler's children would then be brought to Cuzco to be taught about Inca administration systems, then return to rule their native lands. This allowed the Inca to indoctrinate the former ruler's children into the Inca nobility, and, with luck, marry their daughters into families at various corners of the empire. It was traditional for the Inca's son to lead the army; Pachacuti's son Túpac Inca began conquests to the north in 1463 and continued them as Inca after Pachucuti's death in 1471. His most important conquest was the Kingdom of Chimor, the Inca's only serious rival for the coast of Peru. Túpac Inca's empire stretched north into modern-day Ecuador and Colombia.
