Why was Franscio Pizarro so eaisly able to defeat the Inca?

Francisco Pizarro was able to easily defeat the Inca due to a combination of factors, including superior weaponry, tactical advantages, and the impact of internal strife within the Inca Empire. The Spaniards had advanced weapons like guns and horses, which the Inca had never encountered before. Additionally, the capture and subsequent execution of the Inca leader Atahualpa during the ambush significantly weakened their resistance. Finally, existing civil war among the Inca factions further destabilized their ability to unify against the Spanish invaders.
