Monroe was the premier cotton producer in the state of Georgia during the 1900s. The two main cotton mills in Monroe used to be the driving economic force in the region. Now the mills no longer produce for the cotton industry, but rather serve as economic engines for the region by showcasing premiere antique markets, event space, and other unique retail.
In July 1946 the area was the site of the last mass lynching in the United States. A White mob attacked and killed two Black married couples who were driving through the area. The four people were pulled from their car and shot several times.
