Explanation:

Because of the European way of using the land and limited food sources, mass migration to North America created tension between the invaders and the natives. Canadian historian Jan K. Style explains that there were 30,000 Narragansett in Massachusetts in the 17th century. Their chief , "sensing danger ... sought to expand his alliance with the Mohicans to create a general Indian resistance movement.

His efforts to form a united Native American front have failed. In 1643, in a tribal war, he was captured by the  chief of the Mohegan tribe, who handed him over to the English as a rebel.

This illustrates not only the ongoing clashes between the invading colonists and the indigenous population, but also the murderous rivalry and treachery among the tribes, which existed even before the white man arrived in North America at all. The British, in their wars against the French for colonial domination of North America, had some tribes on their side, while others supported the French. No matter which side lost, all the tribes involved paid a losing price.
