After a series of bitter lawsuits between Raritan and Bridgewater in the 1930s and 1940s, the Legislature allowed Raritan to become a fully independent borough by an Act on May 12, 1948, based on the results of a referendum passed on June 12, 1948. The new borough incorporated the old town and an additional portion of Bridgewater Township.
