Question

When early Spanish explorers reached what is now the southwestern United States, they encountered a number of flourishing agricultural centers. When the French arrived a century later, they found many of those villages deserted. Whhat factors played the biggest role in that change?

Answer 1

Answer:

Native Americans were wiped out by European diseases such as Smallpox which was introduced by the Spanish explorers

Explanation:

In the case described above, the factors that played the biggest role in that change, that is, the French arriving a century later, and then found many of those villages deserted is as a result of "Native Americans were wiped out by European diseases such as Smallpox which was introduced by the Spanish explorers."

This is evident in the fact that the Spanish explorers did similar things to the inhabitants of places like Colombia, Peru, and Chile when they got to Southern America, thereby destroying the health and mortality of the native population.
