Warren County, New Jersey has a rich history that dates back to the early 18th century. The area was originally inhabited by the Lenni Lenape Native American tribe until European settlers began to arrive in the late 17th century. In 1738, Warren County was officially established as part of Sussex County, and was named after Joseph Warren, a hero of the Battle of Bunker Hill during the American Revolution.

During the Revolutionary War, Warren County played a significant role in shaping the outcome of the conflict. The area witnessed several key battles and skirmishes, including the infamous Battle of Monmouth in 1778. Many important figures from the revolution, such as George Washington and Alexander Hamilton, traversed through the county during this time. The war left a lasting impact on the region, with numerous historic sites and landmarks still standing today.

The 19th century saw the rise of industry in Warren County, particularly in the form of iron mining and manufacturing. The county became renowned for its vast iron ore deposits and numerous ironworks. This industrial boom led to population growth and the establishment of towns such as Phillipsburg and Hackettstown. However, as the demand for iron declined in the late 19th century, the county's economy began to shift towards agriculture and tourism.

In the 20th century, Warren County experienced periods of both growth and decline. The construction of major highways, such as Route 78 and Route 80, brought increased accessibility to the region, leading to a surge in suburban development in the post-World War II era. However, this growth also brought challenges like urban sprawl and loss of rural landscapes. Yet, Warren County has managed to preserve its natural beauty and historical significance, attracting visitors with its outdoor recreational opportunities and historic sites. Today, Warren County continues to evolve, combining its rich past with a vision for the future.
