County History: Forsyth County was created from Cherokee County on Dec. 3, 1832 by an act of the General Assembly (Ga. Laws 1832, p. 56). [ According to that act, Forsyth County was formed from the 1st, 2nd, 3rd, and 14th districts in the first section of Cherokee County.
Georgia's 81st county was named for former U.S. Representative, U.S. Senator, and U.S. Ambassador to Spain, U.S. Secretary of State, and Georgia Governor, John Forsyth (1780-1841). In particular, it was Forsyth's insistence that Cherokee lands fell under the jurisdiction of Georgia state law that helped force the removal of the Cherokees to the West and the opening up their lands (including those from which Forsyth County was created) to white settlement.
In 1857, portions of Forsyth County were used to help create Milton County.
