Huayna Capac
Sapa Inca Huayna Capac (also spelled Wayna Qhapaq) travelled north to investigate the strangers. Although he did not personally encounter any Spaniards, he contracted smallpox and died in 1527. His eldest son and heir, Ninan Cuyochi, died soon after him. It was uncertain who should be the next Inca king; they had no clear rules of succession. Two sons of Huayna Capac, Huáscar and Atahualpa, born of different mothers, both claimed the position.
