The Battles of Lexington and Concord fought on April 19, 1775, preceded the Battle of Bunker Hill and marked the beginning of armed conflict in the American Revolutionary War.

The confrontations arose from escalating tensions between the American colonies and British authorities, as colonists aimed to oppose British dominance. These battles demonstrated the resolve and capability of colonial militias to confront British forces. This early conflict energized colonial support for independence, fostering increased mobilization and solidarity among the colonies, ultimately leading to the pivotal Battle of Bunker Hill occurring just two months afterward.
