History

Somerset County is one of America’s oldest counties and is named after the English county of Somerset. The area was first settled in 1681, in the vicinity of Bound Brook, and the county was established by charter on May 22, 1688. Most of the early residents were Dutch. General George Washington and his troops marched through the county on several occasions and slept in many of the homes located throughout the area. Somerset County also played an important part during both World War I and World War II with weapons depots and the manufacturing of the army’s woolen blankets.

For much of its history, Somerset County was primarily an agricultural county. In the late 19th century, the Somerset Hills area of Somerset County became a popular country home for wealthy industrialists. The area is still the home of wealthy pharmaceutical industrialists.

In the 1960s, townships that were once exclusively agricultural were quickly transformed into suburban communities. Examples include Bridgewater Township and the Watchung Hills communities of WatchungGreen Brook, and Warren Township. This growth was aided by the development of the county’s very strong pharmaceutical and technology presence. Warren Township used to be considered “the greenest place in New Jersey.” More recently, there has been an influx of New York City commuters who use New Jersey Transit’s Raritan Valley Line and Gladstone Branch or use Interstate 78.
