The major cause of both the Pequot War and King Philip's War was the tension between English settlers and Native American tribes over land and resources. The Pequot War began in 1636 after English colonists in Connecticut accused the Pequot tribe of several attacks, including the massacre of an English settlement in Wethersfield. The war escalated as both sides recruited allies from other tribes, resulting in widespread violence and destruction. King Philip's War, also known as the Metacom's War, occurred in 1675-1676 and was led by Metacom, the chief of the Wampanoag tribe. It was sparked by the murder of Metacom's son by English settlers, and quickly spread to involve numerous Native American tribes and English colonists throughout New England. Both conflicts were rooted in the competing interests of settlers and Native Americans, and had significant consequences for the region's history.
