Why were Spanish able to conquer Incas?

The Spanish were able to conquer the Incas due to a combination of superior military technology, such as firearms and steel weapons, and the strategic use of horses in battle. Additionally, the Incas were weakened by internal strife and civil war, which made them more vulnerable. The Spanish also exploited existing rivalries among indigenous groups, forming alliances that aided their conquest. Finally, the introduction of diseases like smallpox devastated the Inca population, further facilitating Spanish control.
