Who was the leader of the Incan Empire that was strangled to death by Pizarro?

The leader of the Incan Empire who was strangled to death by Pizarro was Atahualpa. He was the last emperor of the Inca civilization before the Spanish conquest. Atahualpa had been captured by Francisco Pizarro during the Spanish expedition into the Incan territory. After being held for ransom, which was paid in a vast quantity of gold and silver, he was ultimately executed by strangulation as Pizarro and his men sought to consolidate their control over the Incan lands. This event marked a significant turning point in the Spanish conquest of the Inca Empire, leading to the collapse of one of the most sophisticated civilizations in pre-Columbian America.

The other figures mentioned in the choices were not leaders of the Incan Empire and were involved in different contexts of exploration or conquest in the Americas. Moctezuma II was the leader of the Aztec Empire, Hernando Cortes was known for his conquest of the Aztecs, and Francisco Vázquez de Coronado explored parts of North America, particularly in present-day southwestern United States. Their leadership roles and historical actions do not relate directly to the events surrounding Atahualpa and the Incan Empire.
