When did the Inca civilidstion cease?

The Inca civilization effectively ceased in the early 16th century, following the Spanish conquest led by Francisco Pizarro. The key event marking the end of the Inca Empire was the capture of the last Inca emperor, Atahualpa, in 1532, which led to the rapid decline of Inca political power and the eventual establishment of Spanish colonial rule. By the late 1570s, the Inca Empire was fully integrated into the Spanish Empire.
