Green Mountain Boys

The Green Mountain Boys were a militia organization established in 1770 in the territory between the British provinces of New York and New Hampshire, known as the New Hampshire Grants and later in 1777 as the Vermont Republic (which later became the state of Vermont). Headed by Ethan Allen and members of his extended family, it was instrumental in resisting New York's attempts to control the territory, over which it had won de jure control in a territorial dispute with New Hampshire.

Some companies served in the American Revolutionary War, including notably when the Green Mountain Boys, led under the command of Ethan Allen who was assisted by Benedict Arnold, captured Fort Ticonderoga on Lake Champlain on May 10, 1775, and invaded Canada later in 1775. In early June 1775, Ethan Allen and his then subordinate, Seth Warner, induced the Continental Congress at Philadelphia to create a Continental Army ranger regiment from the then New Hampshire Grants. Having no treasury, the Congress directed that New York's revolutionary Congress pay for the newly authorized regiment. In July 1775, Allen's militia was granted support from the New York revolutionary Congress.

The Green Mountain Boys disbanded more than a year before Vermont declared its independence in 1777 from Great Britain "as a separate, free and independent jurisdiction or state". The Vermont Republic operated for 14 years, before being admitted in 1791 to the United States as the 14th state.

The remnants of the Green Mountain Boys militia were largely reconstituted as the Green Mountain Continental Rangers. Command of the newly formed regiment passed from Allen to Seth Warner. Allen joined the staff of the Northern Army of New York's Major General Philip Schuyler and was given the rank of lieutenant colonel. Under Warner the regiment fought at the battles of Hubbardton and Bennington in 1777. The regiment was disbanded in 1779.^{: 143–145 : 220}

The Green Mountain Boys mustered again during the War of 1812, the Civil War, the Spanish–American War, the Vietnam War, the Afghanistan War and the Iraq War. Today it is the informal name of the Vermont National Guard, which comprises both the Army and Air National Guards.
