American Revolution: Boston Tea Party: Members of the Sons of Liberty disguised as Mohawk Indians dump hundreds of crates of tea into Boston harbor as a protest against the Tea Act.

The American Revolution (1765–1783) was a colonial rebellion and war of independence in which the Thirteen Colonies broke from British rule to form the United States of America. The revolutionary era reached its zenith with the American Revolutionary War, which commenced on April 19, 1775, with the Battles of Lexington and Concord. The leaders of the American Revolution were colonial separatists who, as British subjects, initially sought greater autonomy. However, they came to embrace the cause of full independence and the necessity of prevailing in the Revolutionary War to obtain it. The Second Continental Congress, which represented the colonies and convened in the present-day Independence Hall in Philadelphia, established the Continental Army and appointed George Washington as its commander-in-chief in June 1775. The following year, the Congress unanimously adopted the Declaration of Independence, which served to inspire, formalize, and escalate the war. Throughout the majority of the eight-year war, the outcome appeared to be uncertain. However, in 1781, a decisive victory by Washington and the Continental Army in the Siege of Yorktown led King George III and the British to negotiate the cessation of colonial rule and the acknowledgment of American independence. This was formalized in the Treaty of Paris in 1783, resulting in the establishment of the United States of America as a sovereign nation.

The Boston Tea Party was a seminal American political and mercantile protest on December 16, 1773, during the American Revolution. Initiated by Sons of Liberty activists in Boston in colonial Massachusetts, one of the original Thirteen Colonies in British America, it escalated hostilities between Britain and American patriots, who opposed British colonial mercantile and governing practices. Less than two years later, on April 19, 1775, the Battles of Lexington and Concord, also in Massachusetts, launched the eight-year American Revolutionary War between the British and the Thirteen Colonies, which ultimately prevailed, securing their independence and the establishment of the sovereign United States of America.

The Sons of Liberty was a loosely organized, clandestine, sometimes violent, political organization active in the Thirteen American Colonies founded to advance the rights of the colonists and to fight taxation by the British government. It played a major role in most colonies in battling the Stamp Act in 1765 and throughout the entire period of the American Revolution. Historian David C. Rapoport called the activities of the Sons of Liberty "mob terror."
