Atahualpa

Atahualpa, Atahuallpa, Atabalipa, or Atawallpa (March 20, 1497 – August 29, 1533), was the last Sapa Inca or sovereign emperor of the Tahuantinsuyu, or the Inca Empire, prior to the Spanish conquest of the Incan Empire. Atahualpa became emperor upon defeating his older half-brother Huáscar in a civil war sparked by the death of their father, Inca Huayna Capac, from an infectious disease which may have been smallpox.
