John Jefferson Adams was born on May 17, 1860, in Slate Springs, Mississippi.[1] [2] He was the son of James Jefferson Adams and Mary (Burson) Adams. James Adams fought for the Confederate Army in the Civil War, in which he died on September 4, 1862. John attended the country schools of Calhoun County, Mississippi, before studying at home.

In 1899, Adams moved to Pittsboro, Mississippi, where he began to practice law in addition to his merchant practice. In Pittsboro, Adams served on the town's Board of Aldermen. Starting in 1900, Adams served on the Democratic Executive Committee of Webster County, Mississippi, and he was its Secretary since 1902. From 1903 onwards, Adams was also on the Democratic Executive Committee of Mississippi's 4th Congressional District. On November 5, 1907, Adams was one of two people elected to represent the 31st District (consisting of Chickasaw, Calhoun, and Pontotoc Counties) in the Mississippi State Senate for the 1908-1912 term.
