Mystic is a village and census-designated place (CDP) in Groton and Stonington, Connecticut. Historically, Mystic was a significant Connecticut seaport with more than 600 ships built over 135 years starting in 1784. Mystic Seaport, one of the largest maritime museums in the United States, has preserved a number of sailing ships, such as the whaling ship Charles W. Morgan. The village is located on the Mystic River, which flows into Fishers Island Sound and, by extension, Long Island Sound and the Atlantic Ocean. The Mystic River Bascule Bridge crosses the river in the center of the village. The name "Mystic" is derived from the Pequot term "missi-tuk" describing a large river whose waters are driven into waves by tides or wind. The population was 4,205 at the 2010 census. History Before the 17th century, the Pequot people lived in this portion of southeastern Connecticut. They were in control of a considerable amount of territory, extending toward the Pawcatuck River to the east and the Connecticut River to the west. To the northwest, the Five Nations of the Iroquois dominated the land linked by the Great Lakes and the Hudson River, allowing trading to occur between the Iroquois and the Dutch. The Pequots were settled just distant enough to be secure from any danger that the Iroquois posed. The Pequot War profoundly affected the Mystic area between 1636 and 1638. In May 1637, captains John Underhill and John Mason led a mission through Narragansett land, along with their allies the Narragansetts and Mohegans, and struck the Pequot Indian settlement in Mystic in the event which came to be known as the Mystic massacre. On September 21, 1638, the colonists signed the Treaty of Hartford, officially ending the Pequot War. English settlement As a result of the Pequot War, Pequot control of the Mystic area ended and English settlements increased in the area. By the 1640s, Connecticut Colony began to grant land to the Pequot War veterans. John Winthrop the Younger, the son of the governor of the Massachusetts Bay Colony, was among those to receive property, much of which was in southeastern Connecticut. Other early settlers in the Mystic area included Robert Burrows and George Denison, who held land in the Mystic River Valley. Settlement grew slowly. The Connecticut government and Massachusetts Bay government began to quarrel over boundaries, thus causing some conflicting claims concerning governmental authority between the Mystic River
