Innovative. Resilient. Revolutionary.

Changing History Since 1776.

Message from the County Executive Dan Benson

In Mercer County, we're proud of the vital part that we played in our nation's struggle for independence. When the Patriot cause was at its lowest, and the hope of liberty seemed to hang by a thread, it was here—in the fields, streets, and waterways of Mercer County—that the tide began to turn.

General George Washington and his troops restored hope with his historic victories during the Ten Crucial Days, reigniting the fight for Independence. This campaign included some of the most important and iconic moments of the Revolution: Washington Crossing the Delaware, the First and Second Battles of Trenton, and the Battle of Princeton.

This history is core to who we are; Mercer County takes its name from General Hugh Mercer, who gave his life for the Revolutionary cause at the Battle of Princeton. Whether you're a Mercer resident, coming from a neighboring county, or visiting from out-of-state, we hope that you'll take the time to explore The Capital County's role in the founding of our nation.

I'd like to extend a special thank you to our Board of Commissioners for their unwavering support. Together, we recognize the profound importance of preserving our heritage, expanding educational opportunities for our young people, strengthening tourism and economic development, and ensuring that every resident across Mercer County, and beyond, can take part in this once-in-a-generation celebration.

Working closely with our towns, schools, nonprofit partners, and historic institutions, we have created a comprehensive website that brings all of our heritage resources together in one place. Here, you can explore our history and find information on tours, reenactments, museums, educational programs, community events, and opportunities to get involved.

We look forward to sharing Mercer County’s incredible Revolutionary story with you as we join our state and our nation in commemorating the 250th anniversary of American independence. Together, let us honor the courage and sacrifice that took place here—and recommit ourselves to the ideals of freedom, democracy, and civic responsibility that continue to guide us to this day.

Welcome to Mercer County, The Crossroad of The Revolution.

Mercer County: The Crossroads of the American Revolution

"Before we were Mercer, we were making history"

Mercer County, New Jersey, played a pivotal role in the founding of the United States, making it central to the upcoming 250th anniversary celebrations. The county’s Washington Crossing State Park marks where General George Washington led his daring crossing of the Delaware River in 1776. A daring act that led to the tides turning for the Continental Army during American Revolution. This feat led directly to the famous victories at the Battles of Trenton, Assunpink Creek, and Princeton, all fought within today’s Mercer County. These successes revitalized the revolutionary cause and convinced many that independence was possible. Beyond the battlefields, Mercer County is tied to the Declaration of Independence through John Witherspoon, President of Princeton University and a Declaration signer, as well as Richard Stockton and John Hart, other influential New Jersey signers. Historic sites, such as the Trenton Battle Monument, Old Barracks Museum, Princeton Battlefield State Park, Morven Museum and Gardens, and Nassau Hall, stand as reminders of these events.

From 2026 to 2033, Mercer County will host commemorations and educational events to honor its revolutionary legacy. Visitors can retrace the steps of the revolutionaries, deepen their understanding of the sacrifices, and understand the visions that shaped the nation. Mercer County’s heritage is a vibrant testament to American resilience and the enduring promise of liberty.
