Early in January 1826, Blackmon and Augustine B. Pope ?stuck? a chestnut stake in the ground and measured off an acre to include the shop already standing. Pope paid Blackmon specified in the sale of the property that Pope ?not carry on any business of a public nature only such pertains exclusively to an apothecary (drug) shop.? the two men had discussed a site for a post office on the settlement and, on January 5, 1826, government authorization came through. John Blackmon was designated as Social Circle?s first postmaster.

In 1832, Social Circle was incorporated. New settlers continued to move in and in June 1836, Mr. John Dally opened a grocery store in the city limits. During 1845, the Georgia Railroad reached this community as it advanced westward. The coming of the railroad was probably the most influential event in Social Circle?s early history and marked this city as the county?s first rail center. A Masonic Lodge was established in 1848 and the first officer was the engineer who had surveyed for the Georgia Railroad.

In 1869 Social Circle was incorporated as a town and limits extended to one-half mile from the center of town in all directions.

Social Circle was highly publicized by a Supreme Court case shortly before the turn of the century , when the town became the center of a freight- rate controversy of national importance, where the railroads challenged a finding of the then-relatively new Interstate Commerce Commission. The Court decision in this instance indirectly brought about another challenge of the Commission?s powers, with the result that Social Circle?s name was widely mentioned and repeated across the country for periods of years.

In 1904, Social Circle surrendered her 1869 charter and was subsequently incorporated as a city. Limits were on mile from the public well at the intersection of Madison, Monroe, Covington, and Gibbs Streets.
