History

Etymology

Established in 1857 as the last county created in New Jersey, it was named after the Union threatened by slavery dispute during this period, which would erupt into civil war in 1861.

History

All of present-day Union County was part of the Elizabethtown Tract, which was purchased in 1664, by English colonists from the Lenape Native Americans that lived in the area of present-day Elizabeth, New Jersey. Union County was formed on March 19, 1857, from portions of Essex County; it was the last of New Jersey’s 21 counties to be established.

Many historic places and structures are to be found in the county, including on the National Register of Historic Places listings in Union County, New Jersey.

Every fall, Union County holds its annual “Four Centuries in a Weekend” festival for the public, celebrating and touring historic buildings, museums and sites in the county.

Geography

According to the 2010 Census, the county had a total area of 105.40 square miles (273.0 km), including 102.86 square miles (266.4 km) of land (97.6%) and 2.55 square miles (6.6 km) of water (2.4%).

Much of Union County is relatively flat and low-lying. Only in the northwestern corner does any significant relief appear as the Watchung Mountains cross the county. It is there that highest elevations, two areas approximately 560 feet (170 m) above sea level, are found in Berkeley Heights. The lowest elevation is sea level along the eastern shore at the Arthur Kill.
