The Ulster-Scots – also known as the Scots-Irish – played a pivotal role in the American Revolution and the birth of the United States. Fleeing religious persecution and economic hardship in the north of Ireland, these fiercely independent Presbyterians settled in the American frontier, particularly in Pennsylvania, Virginia, and the Carolinas. With a frontier spirit, deep-rooted belief in liberty, and experience challenging authority, they were some of the most determined champions of American independence.
When the call for resistance arose, the Ulster-Scots answered with conviction. They filled the ranks of colonial militias and became key figures in decisive battles, helping to turn the tide in favor of the Patriot cause. Presbyterian ministers rallied their communities, with many becoming bold advocates for liberty. Signers of the Declaration of Independence such as Thomas McKean and Matthew Thornton traced their roots directly to Ulster-Scots heritage, and prominent military leaders and statesmen for the new nation emerged from their ranks.
Their legacy is woven into both the foundational ideals and the fighting spirit of America, showing that the Ulster-Scots were were among its most fervent and influential architects of the American Revolution.
