Explanation:

The two empires were vanquished by a similar catholic realm; the Spanish. Despite the fact that the campaigns were lead by various men (Herman Cortes lead the one against the Aztecs and Francisco Pizarro the one against the Inca), the outcome was similar.

Despite the fact that the Aztec set up a superior attack than the Inca, the two realms in the long run surrendered to Spanish military power and following that, European maladies started to run wild in the two domains, causing an extraordinary reduction in the populaces.
