The primary goal of the American militia during the battles of Lexington and Concord was to defend their rights and liberties against perceived British oppression.

Colonists grew increasingly exasperated with British policies, particularly the lack of representation in taxation and the requirement to house British troops. As tensions rose, local militias emerged to safeguard their communities and oppose British control. When conflicts erupted, these militias saw their actions as a defense of their essential rights, reflecting the ideals of self-governance and independence. This dedication to protecting their freedoms not only fueled their involvement in the skirmishes but also set the stage for the larger fight for American independence.
