How was the Spanish conquest of the Inca different from the Spanish conquest of the Aztecs?

The Spanish conquest of the Inca Empire was characterized by a more fragmented and less centralized resistance compared to the Aztec Empire, which had a single ruler, Montezuma II, and a more cohesive political structure. The Inca faced internal divisions and civil war at the time of the Spanish arrival, making it easier for the conquistadors, led by Francisco Pizarro, to exploit these weaknesses. Additionally, the geography of the Andes presented unique challenges and advantages for both sides, influencing the strategies employed by the Spaniards. The role of disease was significant in both conquests, but the Inca were particularly hard hit by epidemics before the Spanish arrived, further undermining their ability to resist.
