Plymouth Colony governor Josiah Winslow leads a colonial militia against the Narragansett during King Philip's War.

Plymouth Colony 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.
