History and settlement
In 1820 the State of Maine was officially separated from Massachusetts, and at that time the name Bridgewater was applied to the Township. The area north of Bangor had been previously divided into 6 mile square townships, and in 1803 the future Bridgewater Township was subdivided into two 3 mile x 6 mile areas, each designated a "grant" area to fund public academies in Portland and Bridgewater, respectively. The town of Bridgewater was incorporated on 2 March 1858.
