During the 1830s and 1840s, Cumming benefited from the gold mining industry as many businesses were created to meet the needs of the miners. However, the California Gold Rush in 1849 put the city into an economic depression. Newly built railroads bypassed the city and took traffic from the Federal Road that ran near Cumming. The city was spared during the Civil War because William T. Sherman did not pass through the city during his March to the Sea. In 1900, the county courthouse was destroyed in a fire; it was rebuilt in 1905.
