Plymouth Colony

Plymouth Colony (sometimes spelled Plimouth) was the first permanent English colony in New England, founded in 1620, and the third permanent English colony in America, after Newfoundland and the Jamestown Colony. It was settled by the passengers on the Mayflower at a location that had previously been surveyed and named by Captain John Smith. The settlement served as the capital of the colony and developed as the town of Plymouth, Massachusetts. At its height, Plymouth Colony occupied most of what is now the southeastern portion of Massachusetts; it was approximately coterminous with the combined territories of Plymouth, Barnstable, and Bristol Counties, all of which were originally established by the General Court of the Plymouth Colony. Many of the people and events surrounding Plymouth Colony have become part of American folklore, including the American tradition of Thanksgiving and the monument of Plymouth Rock.

Plymouth Colony was founded by a group of Protestant Separatists initially known as the Brownist Emigration, who came to be known as the Pilgrims. The colony established a treaty with Wampanoag chief Massasoit which helped to ensure its success; in this, they were aided by Squanto, a member of the Patuxet tribe. Plymouth played a central role in King Philip's War (1675–1678), one of several Indian Wars. The colony was ultimately merged with the Massachusetts Bay Colony and other territories in 1691 to form the Province of Massachusetts Bay.

Despite the colony's relatively short existence, Plymouth holds a special role in American history. The social and legal systems of the colony became closely tied to their religious beliefs, as well as to English custom.
