The enslaved Africans brought their unique Geechee culture, language, and religious traditions from the coast to north Georgia.

Archibald Smith was one of the planters who migrated there to establish a new plantation, also bringing enslaved African Americans from the coastal areas.

Barrington King "leased" or "rented" some of his enslaved adult males to the Roswell Manufacturing Company, but they did not work around the mill machinery.

Since Roswell residents desired a local government, they submitted a city charter for incorporation to the Georgia General Assembly.

During the Civil War, the city was captured by Union forces under the leadership of General Kenner Garrard.

The leading families had left the town to go to safer places well before the Civil War, and arranged for the enslaved people to be taken away from advancing Union troops, as was often the practice.

While many freedmen stayed in the area to work as paid labor on plantations or in town, others migrated to Fulton County and Atlanta for new opportunities.

The South suffered an agricultural depression resulting from the effects of the war and the end of slavery in the United States.

The effects of dramatic African-American migration can be seen by the increase in Fulton County from 20.5% slave in 1860 to 45.7% colored (Black) in 1870.
