Plz Help, and explain What was brought over by the colonists that caused the indigenous people to decrease?

Diseases

Explanation:

When the colonists came, they brought diseases with them (probably unknowingly). The indigenous people were exposed to these diseases that they were not farmiliar with, so many died.

Best Wishes :)

War and violence

Explanation:

War and violence. While epidemic disease was by far the leading cause of the population decline of the American indigenous peoples after 1492, there were other contributing factors, all of them related to European contact and colonization. I hope this helps!
