Plymouth Colony [SEP] Introduction
Plymouth Colony (sometimes Plimouth) was an English colonial venture in America from 1620 to 1691 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 the southeastern portion of Massachusetts. Plymouth Colony was founded by a group of Puritan Separatists initially known as the Brownist Emigration, who came to be known as the Pilgrims. It was the second successful colony to be founded by the English in America after Jamestown in Virginia, and it was the first permanent English settlement in the New England region.
