Answer:
build vast empires in the Americas
Step-by-step explanation:
In the late 1400s and early 1500s, around 90 percent of the Native American population perished due to contagious diseases brought by the Europeans, for which they did not have immunity.
Europeans took advantage of this population loss by defeating most of the civilizations of the continent, and building empires over their remains. The most important examples of the era are the empires that the Spanish and the Portuguese built in what is now Latin America. The French, the Dutch and the British would follow soon, following a similar formula, but each with their own particular national touch.
