Explanation:

Historians and demographers often coincide in the fact that infectious diseases nonexistent in America, carried by the European colonizers, mainly smallpox, were the main factor of the collapse that affected the American Indian population, which had no defenses against them. We must take into account, in addition to the diseases carried by the first explorers, the expansion of the venereal diseases of the Caribbean, especially syphilis, as a cause of the collapse of the population, in addition to the death of indigenous people caused by wars between them. and the Spaniards and their auxiliaries, also indigenous. In addition, we have the variation suffered in the exploitation conditions of the natives by the new lords. Historians and demographers disagree about the degree to which they contributed to the demographic debacle, but there is consensus on the feedback of both groups of causes.
