Inca Roca, the sixth Inca emperor, had a son by a beautiful woman named Mama Micay who was of the Huayllaca tribe. The child was named Titu Cusi Hualpa. The chief of the Ayamarca tribe (neighbors of the Huayllaca tribe), had been promised Mama Micay as his wife by her tribe. He never forgave the Huayllaca tribe for this broken oath, and war broke out between the Ayamarca and the Huayllaca. The latter was a weaker tribe and it was not long before they were subdued by the Ayamarca. The chief of the Ayamarca then demanded the child of Inca Roca and Mama Micay, Titu Cusi Hualpa. The boy, who was only eight years old, was sent to the Ayamarca by Inca Roca. When he was given to the chief, the boy threatened to put a curse on the Ayamarca if they harmed him, and having said these words, wept tears of blood. He was held hostage by the Ayamarca for several years before he was returned to the Inca. He later became the seventh Inca emperor, Yahuar Huacac, which means 'he who weeps blood' in the Inca language.
