Essex County has played a central role in New Jersey’s political, industrial, cultural, and transportation development since the colonial period.

Located in northeastern New Jersey, Essex County sits directly west of Manhattan and includes a wide range of municipalities—from the dense urban environment of Newark to the suburban communities of Montclair, Livingston, and Millburn, and the preserved green spaces of the Watchung Mountains.

The county’s identity reflects its long history of commerce, manufacturing, civic leadership, and transit connectivity.

Early Settlement and Colonial Development

The land that is now Essex County was originally home to Lenape communities before Dutch and later English settlers arrived in the 1600s.

The Lenape lived throughout the region along the Passaic River, the Newark Bay coastline, and the upland ridges. Dutch settlers established trading posts and farmland, but English influence grew quickly after the late 1600s. Newark, founded in 1666 by Puritans from the New Haven Colony, became one of the earliest organized towns in New Jersey.

Essex County was established in 1683 and became one of New Jersey’s first counties. Newark developed into a local government and commercial center early, positioning the county as a strategic point of administration and trade.

Role in the American Revolution

The county’s roads and ridges were used for troop movement and signal points. Washington’s forces passed through the region multiple times. Several preserved sites, such as the Washington’s Headquarters marker in Newark and the Revolutionary-era stone houses in Montclair and Caldwell, remain part of local historical networks.

Industrial Growth, Transportation, and Immigration

During the 19th and early 20th centuries, Essex County became a major industrial and transportation hub.

Newark grew into a manufacturing center known for leather goods, jewelry, beer brewing, pharmaceuticals, and shipping.

Factories clustered near rail lines, the Morris Canal, and Newark’s port facilities along the Passaic River. Nearby towns including Orange, West Orange, and Bloomfield developed streetcar suburbs that supported a growing workforce.

Thomas Edison in West Orange

West Orange became home to Thomas Edison’s laboratory and industrial complex, now the Thomas Edison National Historical Park. Many of Edison’s experiments and inventions were carried out here, including work on lighting, motion pictures, and sound recording.

Immigration Waves

The county saw successive waves of immigrants:

  • Irish and German workers in the 1800s
  • Italian, Polish, and Jewish communities in the late 1800s–early 1900s
  • Portuguese and Brazilian communities particularly in Newark’s Ironbound
  • Caribbean, West African, South American, and East Asian communities in the late 20th century onward

These communities shaped neighborhood identities, food, business districts, and civic organizations.
