Death of Huayna Capac During Epidemic

Huayna Capac, the eleventh Sapa Inca, died during an epidemic in Quito while campaigning in the northern provinces. The disease, likely smallpox transmitted through trade networks from Spanish-controlled territories, also killed his designated heir Ninan Cuyuchi. Without a clear successor, competing claims between his sons Huascar in Cusco and Atahualpa in Quito triggered a civil war that fractured Tawantinsuyu, leaving the empire vulnerable to Spanish conquest within a decade.
