Inca Rock , sixth monarch of Cuzco and the first of the Hanan Cuzco dynasty , he came to power conspiring against Capac Yupanqui, whom he killed by making him drink a potion. The first measure he adopted was to marry Cusí Chimbo, widow of the late Capac Yupanqui, a fact that demonstrates the complicity of both in the disappearance of the aforementioned monarch. He divided the powers in such a way that the Inca chief of the Urin faction was solely in charge of the priesthood of the Sun, with fixed residence in the Inticancha. The Incas of Hanan, on the other hand, began to exercise civil, political, economic, judicial and martial control. The duality of power was maintained, but the Inca Hanan had more power than the Urin, dedicated exclusively to ritual purposes except on certain occasions when he could replace the Inca Hanan. To neutralize the Urin Cuzco, Inca Roca had to conquer the Masca (Paruro) and convert them into his allies; the lord of the masca Cusí Huaman, was captured and taken to live in Cuzco. He then definitively defeated the pinaguas (Muyna) in a bloody battle in which his lord died. He immediately entered Quiquijan and subdued Caitomarca (30 km south of Cuzco), but he made the mistake of leaving no garrisons in that area and soon lost it. Meanwhile, the Chancas had already reached the Apurímac River, waiting for the time to raid the kingdom of the Ayarmacas, which they did not achieve since Inca Roca obtained the reinforcement of troops from Canas and Canchis. After a few years he directed his attention to the east, reaching Paucartambo and stopping only in front of the tropical forest. Despite his expansionist desires, he made the same mistake as his ancestors by invading and conquering lands, confiscating rich booty (clothes, coca, food, herds of cattle) and not worrying about annexing territories definitively .
Works and family life of Inca Roca
To mark his separation from the Urin, he abandoned Inticancha and had his own palace built; Being established since then that each Inca had to build his own residence, not inheriting or occupying that of his predecessor. The Urin Incas, on the other hand, would continue to live in the Inticancha, according to the function they fulfilled. He made improvements to the Cuzco llacta, ordering the channeling of the Huatanay River and the opening of channels to supply the four neighborhoods that made up the city. He was also concerned that the young elite be instructed in the art of war, the management of quipus (accounting system based on knots and colored ropes) and knowledge of its history. He married Mama Micay, daughter of the Lord of Huallacán (Yucay), from whose union Tito Cusí Huallpa was born. The marriage angered the Ayarmacas, because Micay had been engaged to the lord of this ethnic group, and for this reason a civil war began that lasted a few years. Peace was conditioned on the delivery of little Tito Cusí Huallpa to the Ayarmacas, who tried to kill him, desisting when they saw the child cry tears of blood. Inca Roca did not dare to start the assault on the Ayarmaca, fearing for the life of his son, a situation that lasted for about a year, until Chimbo Orma, wife of Tomay Capac (Lord of the Ayarmaca), devised a plan to free the child with the help of the elders, who from that moment received preferential treatment. After many years, both groups reaffirmed the definitive peace through the exchange of women:Mama Chiquia, daughter of Tocay Capac, was given to Tito Cusí Huallpa, while the ñusta (princess) Curi Ocllo, daughter of Inca Roca, was given as his wife. to the king of the ayarmacas. Inca Roca died very old and his funeral was attended by the lords of the kingdoms of Contisuyo, Urcos, Ayarmaca, many women who loved and served him in life hanged themselves with their hair to accompany him in the afterlife. His descendants were grouped in the panaca called Vicaquirao .
