The First Continental Congress met in 1774 to respond to the crisis in Boston and agreed to continue boycotting British goods while preparing militias. In April 1775, British troops marched to Concord to seize weapons from the colonists, sparking the Battles of Lexington and Concord where the "shot heard round the world" was fired, beginning the Revolutionary War. The Second Continental Congress then met and appointed George Washington as commander of the newly formed Continental Army to defend the colonies.
