Officially founded in 1838 and carved out of other surrounding counties, Mercer County has
a historical impact that reaches back to the pivotal battles of the American Revolutionary War.
General George Washington led his famous December crossing of the Delaware and routed
the Hessians right here in Mercer County. That turning point of our country's struggle for
independence & liberty is just one of the many historically significant things to have happened
here in Mercer.
Further, when the Revolutionary War concluded, the City of Trenton and Princeton Township
took turns serving as the temporary Federal Capital.
The county is named in honor of General Hugh Mercer, a distinguished hero of the Revolution,
who died from wounds inflicted during the Battle of Princeton in 1777.
Other notable historical figures of America's past have also become part of the history of
Mercer County. Former Vice President Aaron Burr, Presidents Grover Cleveland and Woodrow
Wilson, and the Marquis de Lafayette have all become part of the history of Mercer County.
Mercer County also has the dubious distinction of being the famed landing spot for a Martian
invasion of the United States. In 1938, in what has become one of the most famous radio
addresses of all time, Orsen Welles acted out his 'War of the Worlds' invasion. Wells landed
his imaginary aliens on Mercer County soil, using what is now West Windsor Township as the
point of first contact. And our history is continually being added to daily by our residents.
