Because the rapidly expanding Inca Empire was internally weak, conquest was remarkably easy. After the Inca Emperor Huayna Capac died in 1527, his sons Huascar and Atahualpa fought over the succession. Although Atahualpa defeated his brother, he had not yet consolidated his power when the conquistadors arrived. Atahualpa did not attempt to defeat Pizarro when he arrived on the coast in 1532 because the Incan ruler was convinced that those who commanded the mountains also controlled the coast. Atahualpa's refusal to accept the permanent Spanish presence and to convert to Christianity led to the bloody Battle of Cajamarca on 16 November 1532. Pizarro killed Atahualpa's 12-man honor guard and took the Inca captive at the so-called ransom room. One year later, the Inca capital of Cuzco fell and was refounded as a new Spanish settlement.
