Mercer County occupies a central geographic location in New Jersey and has played a key role in the history of this state and the nation. It was here that the battles of Trenton and Princeton marked a pivotal turning point in America's struggle for independence. As a free nation grew, Mercer County kept its place on the historical stage as capitol of New Jersey, home to Princeton University, and site of booming industries such as the Roebling Wire Mills and numerous potteries.

This site is an effort to illuminate Mercer County's place in American history.
