Atahuallpa or Atawallpa (c. 1502 – 1533) was the 13th and last sovereign emperor of the Tahuantinsuyo, or Inca empire. He became emperor after defeating his younger half-brother Huáscar in a civil war that followed the death of their father, Inca Huayna Capac, from an infectious disease (maybe malaria or smallpox). During the civil war, the Spaniard Francisco Pizarro arrived and captured Atahuallpa, and used him to control the Inca empire. Eventually, the Spanish executed Atahuallpa. So ended the Inca Empire (although several weak puppet successors followed him.)
