## History

The township was formed on March 29, 1749, from portions of Hanover Township, Morris Township and Roxbury Township. After the Revolutionary War, on February 21, 1798, the township was incorporated by the Township Act of 1798 of the New Jersey Legislature as one of the state's initial group of 104 townships. Portions of the township were taken to create Randolph Township on January 1, 1806. Mendham Borough became an independent municipality when it was formed on May 15, 1906.
Natural resources of water, forests and minerals drew settlers to the area. The area of Ralston had iron forges, sawmills, and a gristmill by 1748, located in an area along the North Branch of the Raritan River. Northeast of Ralston is India Brook. On the eastern side of Mendham Township, brooks that formed the upper reaches of the Whippany River attracted settlers to the valley called Water Street or Waterville, later known as Brookside.
Following the Civil War, wealthy industrialists and financiers established country homes in the Morristown area and Bernardsville's "Mountain Colony", including in the Mendhams. Historic homes, structures, and local settlements are relics of the township's history as a community where people lived and worked in a rural community far from the city's "dark satanic mills".
