Swansea is a town in Bristol County in southeastern Massachusetts. It is located at the mouth of the Taunton River, just west of Fall River, 47 miles (76 km) south of Boston, and 12 miles (19 km) southeast of Providence, Rhode Island. The population was 15,865 at the 2010 census.
The villages of Hortonville, Barneyville and Ocean Grove are located in the town.
Swansea was named for the Welsh city of Swansea, which had been the hometown of some original settlers. John Miles, the founder of the first Baptist Church in Wales, moved to Swansea in 1662/3. William Brenton had purchased the land from Native Americans. Parts of its territory were originally part of Rehoboth, Massachusetts.
In 1667 the first Baptist church in Massachusetts relocated to Swansea from Rehoboth after experiencing religious intolerance there, and Swansea was incorporated as an independent town. Initially, the town established a committee to assign rank of 1, 2, or 3 to the residents with the first getting 3 acres of land, the second 2, and the third 1. The committee could promote and demote residents as it saw fit. The system collapsed in 1681 when the committee voted to make five residents the highest rank and to make the rank hereditary.
