About how Long did it take the Spanish to conquer the capital city of the Inca?

The Spanish conquest of the Inca capital, Cusco, began in 1532 and was largely completed by 1536. The initial takeover occurred after the capture of the Inca emperor Atahualpa, but resistance continued for several years. Therefore, it took roughly four years for the Spanish to fully establish control over the city and the surrounding region.
