History of Salem County

What Does "Salem" Mean?

The name "Salem" comes from the Hebrew word shalom, which means "peace". Early settlers, especially Quakers, chose this name because the area felt very calm and peaceful to them.

How Salem County Began

European settlers from England first arrived in the 1600s. They started a court here in 1681. Salem County was officially formed on May 17, 1694. It was part of an older area called the Salem Tenth within West Jersey.

The Old Salem County Courthouse is a very special building. It was built in 1735 and is the oldest courthouse still in use in New Jersey. It's also the second oldest courthouse in continuous use in the entire United States! The building has been made larger over the years, but its unique bell tower is still the same.

During the American Revolutionary War, an important event happened near here. A judge named William Hancock was killed by the British during the Salem Raid in 1778. After this, the courthouse was used for "treason trials." People suspected of helping the British were put on trial.

A fun legend from the courthouse involves tomatoes! Before 1820, many Americans thought tomatoes were poisonous. But in 1820, a man named Colonel Robert Gibbon Johnson supposedly stood on the courthouse steps and ate tomatoes in front of a big crowd to show they were safe to eat.

Salem County is also known for its special Quaker-style buildings from the 1700s. For a long time, it was mostly a farming area. In the early 1900s, many new people from Europe moved here. After World War II, more people moved to the county as towns grew. The Delaware Memorial Bridge was built to help with the increased traffic.
