The 10-month siege of Cusco by the Inca army under the command of Sapa Inca Manco Inca Yupanqui started on 6 May 1536 and ended in March 1537. The city was held by a garrison of Spanish conquistadors and Indian auxiliaries led by Hernando Pizarro. The Incas hoped to restore their empire (1438–1533) with this action, but it was ultimately unsuccessful.
