Spain succeeded in conquering so much of the Americas because they used their religion as a main belief, the spread of European diseases weakened the Americas conquests, the Spanish soldiers and sailors had excellent fighting skills and used advanced weapons on the Native American armies, and lastly, Spain made alliances with the Native Americans, the enemies of the Incas and Aztecs.

They also had some of the newest sea fairing technology available and hired Portuguese pilots with maps. The motivation was also there to find gold and riches for the crown as well as a water route to Asia.
