[1] Active in the militia in Connecticut during the French and Indian War and Vermont during the Revolution, and continuing his military service after the Revolution, Strong eventually attained the rank of Brigadier General.
[4][5] In 1783 he returned to Addison, and he represented that town in the Vermont House from 1784 to 1787, serving as Speaker in 1786.
In 1791 Strong was a member of the convention that ratified the U.S. Constitution and resulted in statehood for Vermont.
[8] In the 1790s Strong built a home in Addison to replace his original dwelling, which had been destroyed by the British during John Burgoyne's advance from Canada during the Revolution.
This home, the General John Strong Mansion, is a museum operated by the Vermont chapter of Daughters of the American Revolution.
