The area that is now Mahwah was originally formed as Hohokus Township on April 9, 1849, from portions of Franklin Township (now Wyckoff). While known as Hohokus Township, territory was taken to form Orvil Township (on January 1, 1886; remainder of township is now Waldwick), Allendale (November 10, 1894), Upper Saddle River (November 22, 1894) and Ramsey (March 10, 1908). On November 7, 1944, the area was incorporated by an act of the New Jersey Legislature as the Township of Mahwah, based on the results of a referendum held that day, replacing Hohokus Township.[24]
