The major development following the initial skirmishes at Lexington and Concord was the formation of the Continental Army.

Acknowledging the need for a unified military response to British forces, the Second Continental Congress met in May 1775 and created a cohesive army. George Washington was chosen as its commander, highlighting the critical role of leadership and organization in the fight for independence. The establishment of the Continental Army marked a crucial advancement toward a more organized and formal military strategy, allowing the colonies to enhance their coordination during the Revolutionary War.
