The next settlement at Sagadahoc was about 1660, when the land was taken from an Indian sagamore known as Robinhood. Incorporated as part of Georgetown in 1753, Bath was set off and incorporated as a town on February 17, 1781. It was named by the postmaster, Dummer Sewall, after Bath in Somerset, England. In 1844, a portion of the town was set off to create West Bath. On June 14, 1847, Bath was incorporated as a city, and in 1854 designated county seat. Land was annexed from West Bath in 1855.
