The Pequot War 1634-1638
The Pequot War was an armed conflict between the Pequot tribe and an alliance of the English colonists of the Massachusetts Bay, Plymouth, and Saybrook colonies and their Native American allies (the Narragansett and Mohegan tribes). The war concluded with the Pequots losing. At the end, about seven hundred Pequots had been killed or taken into captivity. Hundreds of prisoners were sold into slavery to the West Indies; other survivors were dispersed. The colonial authorities classified the tribe as extinct; however, survivors remained in the area and did regain recognition and land along the Thames and Mystic rivers in southeastern Connecticut.

King Philip's War 1675-1678
King Philip's War (sometimes called the First Indian War or Metacom's War) was an armed conflict between American Indian inhabitants of present-day New England and English colonists and their Indian allies. The war is named for Metacomet (1638-1676), the Wampanoag chief who adopted the English name Philip due to the friendly relations between his father (the Wampanoag chiel Massasoit) and the Mayflower Pilgrims. The war continued in northern New England until the signing of the Treaty of Casco Bay in April 1678.
French & Indian War 1754-1763
The French and Indian War was the North American portion of the worldwide Seven Years' War of 1754–1763. The war pitted the colonies of British America against those of New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as by Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Following months of localised conflict, the various nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict. The name French and Indian War, used mainly in the United States, refers to the two main enemies of the British colonists: the royal French forces and the various indigenous forces allied with them.
