What was King Philip’s War?

In the 17th century, about 8,000 Amerindians lived in the area. When the first European settlers moved into the area, such as the Pilgrims in 1620, there was no animosity between them and the Amerindians. In fact, without help from Massasoit and other Amerindians, the Pilgrims would have likely starved that first winter. That was soon to change thanks to the Europeans endless search for land and wealth. Thinking that the various tribes should be under their colonial rule the English made things very tense and in 1675 Metacomet, son of Massasoit joined the fight. Metacomet was also known as King Philip and the conflict was called King Philip's War.
