The Neo-Inca State, also known as the Neo-Inca state of Vilcabamba, was the Inca state established by Inca emperor Huayna Capac's son Manco Inca Yupanqui in Vilcabamba in 1537. It is considered the remnants of the Inca Empire (1438–1533) after the Spanish conquest. It lasted until 1572, when the last Inca stronghold was conquered, and the last ruler, Túpac Amaru, Manco's son, was captured and executed. This ended resistance to the Spanish conquest under the political authority of the Inca state.
