In 1775, the American Revolutionary War escalated dramatically. The year began with skirmishes such as the Battles of Lexington and Concord in April, marking the first military engagements between colonial militia and British troops. These clashes fueled colonial sentiment against British rule and bolstered the call for independence. The siege of Boston followed, with colonial forces tightening their grip around the city. Meanwhile, George Washington was appointed commander-in-chief of the Continental Army in June, signaling a pivotal moment in the colonies' unified resistance. By year's end, tensions were high, battles were fought, and the stage was set for a full-scale war for independence in the coming years.
