History

Created in 1818 by an act of the Georgia General Assembly, Gwinnett County was formed from parts of Jackson County (formerly part of Franklin County) and from lands gained through the cession of Indian lands. Named for Button Gwinnett, one of the signatories of the Declaration of Independence, the first county court was held at the home of Elisha Winn, and the county seat was placed at Lawrenceville.

In 1861, all three of Gwinnett County’s representatives at the Georgia Constitutional Convention (1861) in Milledgeville voted against secession. Towards the end of the war, several skirmishes took place in Gwinnett County as part of the Atlanta Campaign.
