The Pequot War was a conflict that took place in New England between 1636 and 1638, involving the Pequot nation against an alliance of English colonists from the Massachusetts Bay, Plymouth, and Saybrook colonies, supported by Indigenous allies from the Narragansett and Mohegan nations. The war emerged from tensions in the colonial frontier of southern New England during the early period of English settlement.
The war culminated in a decisive military engagement known as the Mystic massacre, in which English colonists from Connecticut Colony and their allies attacked the village of Pequot Fort. During this assault, the colonists set the village ablaze, blocked the exits to prevent escape, and killed those attempting to flee. This engagement resulted in approximately 700 Pequots being killed or taken into captivity. Following their military defeat, hundreds of surviving Pequot prisoners were sold into slavery and transported to colonists in Bermuda or the West Indies, while other survivors were dispersed as captives among the victorious nations.
The war concluded with the Treaty of Hartford in 1638, which sought to eradicate Pequot cultural identity by prohibiting the Pequots from returning to their lands, speaking their tribal language, or referring to themselves as Pequots. This treaty effectively eliminated the Pequot nation as a viable political entity in southern New England, with colonial authorities classifying them as extinct. Survivors who remained in the region were absorbed into other local Indigenous nations, marking a significant shift in the regional balance of power and Indigenous sovereignty.
European colonization of North America accelerated after 1600, with England, France, Spain, and the Netherlands establishing competing settlements along the Atlantic coast, the St. Lawrence River, the Gulf of Mexico, and the Mississippi Valley. The first permanent English settlement at Jamestown, Virginia (1607) struggled with starvation and conflict; the Plymouth colony (1620) and the Massachusetts Bay Colony (1630) followed. By the mid-1700s, thirteen English colonies stretched along the Atlantic seaboard, governed through a mix of royal charters, proprietary grants, and elected assemblies. The colonial economy depended on tobacco in Virginia and Maryland, rice and indigo in the Carolinas, and maritime trade in New England — all increasingly reliant on enslaved African labor after 1619. Conflict with Indigenous peoples over land was continuous, punctuated by major wars including King Philip's War (1675–1676) in New England and the Yamasee War (1715–1717) in the South. The French and Indian War (1754–1763), part of the global Seven Years' War, ended French power in North America and left Britain deeply in debt — triggering the taxation disputes that would lead to revolution.
