Which battle is recognized as the first major armed clash of the American Revolutionary War, remembered during America250?

The Battles of Lexington and Concord were the first major armed clashes of the American Revolutionary War.

The fighting took place in Massachusetts on April 19, 1775, after British regulars marched from Boston to seize colonial military supplies in Concord. Colonial militia assembled at Lexington, where the first confrontation occurred. The British column then continued toward Concord before retreating to Boston under sustained fire from militia along the road.

The battles transformed a political dispute into open warfare. News of the fighting spread rapidly through the colonies, encouraging militia mobilization and helping produce the Siege of Boston. The conflict had not yet become a formal declaration of independence; that declaration came more than a year later.

The phrase “shot heard round the world,” associated with Ralph Waldo Emerson’s later poem, refers to the opening of the American Revolution. The event is sometimes called the Battles of Lexington and Concord, while British accounts historically emphasized Lexington and Concord separately.
