Tupac Inca Yupanqui, the son and successor of Pachacutec, completed the subjugation of the coast valleys, extended his conquests beyond Quito on the north and to Chile as far as the river Maule in the south, besides penetrating far into the eastern forests. Huayna Ccapac, the son of Tupac Inca Yupanqui, completed and consolidated the conquests of his father. He traversed the valleys of the coast, penetrated to the southern limit of Chile, and fought a memorable battle on the banks of the “lake of blood” (Yahuar-cocha), near the northern frontier of Quito. After a long reign,[1175] the last years of which were passed in Quito, Huayna Ccapac died in November, 1525. His eldest legitimate son, named Huascar, succeeded him at Cuzco. But Atahualpa, his father’s favorite, was at Quito with the most experienced generals. Haughty messages passed between the brothers, which were followed by war. Huascar’s armies were defeated in detail, and eventually the generals of Atahualpa took the legitimate Inca prisoner, entered Cuzco, and massacred the family and adherents of Huascar.[1176] The successful aspirant to the throne was on his way to Cuzco, in the wake of his generals, when he encountered Pizarro and the Spanish invaders at Caxamarca. This war of succession would not, it is probable, have led to any revolutionary change in the general policy of the empire. Atahualpa would have established his power and continued to rule, just as his ancestor Pachacutec did, after the dethronement of his brother Urco.[1177] The succession of the Incas from Manco Ccapac to Atahualpa was evidently well known to the Amautas, or learned men of the empire, and was recorded in their _quipus_ with precision, together with less certain materials respecting the more ancient dynasties. Many blunders were committed by the Spanish inquirers in putting down the historical information received from the Amautas, but on the whole there is general concurrence among them.[1178] Practically the Spanish authorities agree, and it is clear that the native annalists possessed a single record, while the apparent discrepancies are due to blunders of the Spanish transcribers. The twelve Incas from Manco Ccapac to Huascar may be received as historical personages whose deeds were had in memory at the time of the Spanish invasion, and were narrated to those among the conquerors who sought for information from the Amautas.
