What were the factors of the conquest of the Incas?

The conquest of the Incas was primarily driven by Spanish conquistadors led by Francisco Pizarro, who exploited internal strife within the Inca Empire, particularly the civil war between Atahualpa and Huáscar. The Spanish also benefitted from superior military technology, including firearms and steel weapons, as well as the strategic use of horses in warfare. Additionally, the Incas were unprepared for the impact of European diseases, which decimated their population and weakened their resistance. Lastly, alliances with discontented indigenous groups played a crucial role in the Spanish success against the Inca forces.
