Union County, NJ: Movement, Memory, and the Muscle That Keeps New Jersey Going

Spanning from Elizabeth’s portside grit to the green quiet of Mountainside, Union County, New Jersey is more than a geographic region—it’s a crossroads of migration, resistance, and possibility.

Industrial Engine: Cities like Elizabeth and Linden thrived in the 19th and 20th centuries as centers of shipping, railroads, and manufacturing—drawing Black migrants from the South and immigrants from Europe and the Caribbean.
