American Revolution: Battle of Springfield fought in and around Springfield, New Jersey (including Short Hills, formerly of Springfield, now of Millburn Township).

The American Revolution (1765–1789) was a political movement in the Thirteen Colonies of Great Britain. The movement began as a rebellion and evolved into a revolution resulting in the sovereign United States. These changes were the outcome of the associated American Revolutionary War. The Second Continental Congress, as the provisional government, established the Continental Army and appointed George Washington as its commander-in-chief in 1775. The following year, the Congress passed the Lee Resolution on July 2nd, then unanimously adopted the Declaration of Independence on the Fourth of July. Throughout most of the war, the outcome appeared uncertain. However, in 1781, a decisive victory by Washington and the Continental Army in the Siege of Yorktown led King George III and the Fox–North coalition in government to negotiate the cessation of colonial rule and the acknowledgment of American sovereignty, formalized in the Treaty of Paris in 1783. The Constitution took effect in 1789 and the Bill of Rights was ratified in 1791.
