What caused the indian wars of 1864-1890

The Increasing Tensions.

Explanation:

As the colonies grew, they expanded westward. By the 1750s, British colonists were moving into areas also claimed by France. The increasing tensions soon led to war. In 1754, French forces joined with some Native American groups. Together they drove British colonists from land west of the Appalachian Mountains. The conflict was called the French and Indian War. It led to war between Great Britain and France in Europe.
