The Inca Civil War, also known as the Inca Dynastic War, the Inca War of Succession, or, sometimes, the War of the Two Brothers, was fought between half-brothers Huáscar and Atahualpa, sons of Huayna Capac, over succession to the throne of the Inca Empire. The war followed Huayna Capac's death. It began in 1529, and lasted until 1532. Huáscar initiated the war; appointed as emperor and claiming the throne, he wanted to defeat Atahualpa's competition. Atahualpa was tactically superior to his brother in warcraft and to the mighty armies of Cusco, which their father had stationed in the north part of the empire during the military campaign. Accounts from sources all vary in the exact details. Following Atahualpa's victory, Spanish forces led by Francisco Pizarro invaded this region. He ultimately captured and killed Atahualpa, after receiving a ransom that was purportedly to free him. The Inca Civil War has been characterized as an important factor in enabling the Spanish conquest of the Inca Empire.
