Huáscar Inca (ˈwɑːskɑr; Quechua: Waskar Inka) also Guazcar (before 1527 - 1532) was Sapa Inca of the Inca Empire from 1527 to 1532. He succeeded his father, Huayna Capac and his brother Ninan Cuyochi, both of whom died of smallpox while campaigning near Quito.
The origin of his name is uncertain. One story is that Huáscar was named after a huge gold chain that was made to mark the occasion of his birth. "Huasca" is Quechua for "chain." Because his father did not think "chain" was an appropriate name for a prince, he added an r to the end of the name to make "Huáscar". Another story is that his name is from his birthplace, Huascarpata.
The actual events that brought about Huáscar's succession are unclear. Conflicting factions and the fact that the Spanish chroniclers' accounts stemmed from the winners of the ensuing civil war led to conflicting versions of what actually happened. Thus, although Huayna Capac named the infant Ninan Cuyochi as his first heir, sources differ as to whether the boy died first, was unacceptable because of an unfavorable divination or even if Huayna simply forgot that he had named him when asked to confirm the nomination. In any event, a second choice was requested and again sources vary. He may have named Huáscar's half-brother Atahualpa who then refused or named Huáscar himself or perhaps even the nobles put forward Huáscar. Whatever the truth, the result of Huáscar's accession and the dispute over it before and after led to civil war between Huáscar (made emperor by a faction based in Cuzco) and Atahualpa (backed by leaders who were based in the north with Huayna).
The Spanish chronicler Juan de Betanzos who provided information pertaining to the Huáscar-Atahualpa civil war, outlines Huáscar's tyranny. It is, however, a very biased account, as Betanzos' wife, on whose testimony much of his chronicle is based, was previously married to Atahualpa. Betanzos outlines how Huáscar would seize his lords' wives if they took his fancy. More importantly, he seized both the Lands of the Previous Incas and the Lands of the Sun.
