In 1649, Ousamequin (Massasoit) sold the surrounding land, then known as Saughtucket, to Myles Standish as an addition to Duxbury. Brockton was part of this area, which the English renamed Bridgewater, until 1821, when it became the town of North Bridgewater. Its name changed in 1874, after a contentious process finally decided on naming it after Isaac Brock (the initial British commanding general at Queenston Heights, where invading American troops suffered a rout, in 1812), after a local merchant heard of Brockville, Ontario, on a trip to Niagara Falls. Brockton became a city on April 9, 1881.
