County of mercer

History & Founding

Located in the heart of central New Jersey, this county boasts a rich history and a dynamic present. Established in 1838 from portions of Hunterdon, Middlesex, and Burlington counties, its name honors Brigadier General Hugh Mercer, a Scottish soldier who fought alongside George Washington during the Battle of Princeton in 1777. Mercer was mortally wounded in that battle, and his bravery and sacrifice became a source of local pride, leading to the county's naming. Prior to Mercer County's formation, the area was largely agricultural, inhabited by Dutch and English settlers. Trenton, the county seat, played a crucial role in the American Revolutionary War, witnessing two significant battles. An interesting anecdote from the county’s early history recounts a desperate attempt by Continental soldiers to retrieve cannons left behind after a retreat from Trenton, narrowly avoiding capture by Hessian troops. The county’s development mirrored New Jersey’s broader trajectory, transitioning from an agrarian landscape to a more industrialized and suburbanized region.
