Union County’s history reflects the development of early American settlement, industry, transportation, and suburban growth shaped by its proximity to New York City.

Located in north-central New Jersey, Union County sits within the New York metropolitan region, bordered by Essex County to the north and Middlesex County to the south. The county includes older urban centers, traditional downtowns, and suburban residential communities, along with notable historic sites and park systems. Its identity draws from several centuries of layered development.

Early Settlement and County Formation

The region was originally inhabited by Lenape communities who utilized the rivers, forests, and meadows that shaped local travel routes and seasonal settlements.

European settlement began in the 1600s, with Dutch and later English settlers establishing farms and small villages along the Elizabeth River and Newark Bay. These early settlements developed into organized towns with commercial and civic institutions.

Union County was formed in 1857, separating from Essex County as population density increased and local administrative needs grew. The name “Union” references the political climate leading up to the Civil War, symbolizing the preservation of the country as one unified nation.

Elizabeth as a Colonial Center

Elizabeth, originally founded as Elizabethtown in 1664, became one of the earliest permanent English settlements in New Jersey. It served as a colonial capital at various points and later developed into a significant port and transportation hub.

Revolutionary War activity occurred throughout the region, including troop movements, skirmishes, and encampments around Elizabeth and the surrounding townships. Several sites still mark these events through monuments and preserved buildings.

Industrial Growth, Railroads, and Manufacturing

The 19th and early 20th centuries brought industrial expansion supported by rail and maritime transportation networks.

Elizabeth and Linden developed manufacturing facilities tied to shipping, textiles, machinery, chemicals, and later automobile-related industries. Rahway became known for printing, metalwork, and milling operations. Towns such as Plainfield and Summit evolved into residential communities with rail access for commuters.

Transportation and Commerce

Key transportation corridors include:

  • Central Railroad of New Jersey
  • Pennsylvania Railroad lines
  • Port terminals along Newark Bay
  • The later development of the New Jersey Turnpike and Garden State Parkway

These networks supported both commercial freight and residential commuting patterns, linking Union County to New York City and other regional employment centers.

Aviation and the Modern Industrial Shift

The county is home to portions of Newark Liberty International Airport, a major U.S. aviation gateway. Industrial redevelopment, logistics, and warehousing continue to play significant roles in the county’s economy today, particularly in Elizabeth, Linden, and surrounding waterfront areas.
