Brantley was born in
Blackshear, the
county seat of
Pierce County, Georgia. He attended the
University of Georgia in
Athens. After his graduation, he passed the law examinations and gained admission to the state bar in 1881, and began practicing law in Blackshear. Brantley served in both legislative chambers of the bicameral
General Assembly of Georgia during the 1880s. He was first elected to the lower chamber, the
Georgia House of Representatives, in 1884 and 1885, and subsequently to the upper house,
Georgia Senate, in 1886 and 1887. In 1888, he became
solicitor general of the state
circuit court in
Brunswick. In 1896, Brantley successfully ran for federal office, winning election as a
Democratic candidate to the
United States House of Representatives in in the northwest region of the state. He was re-elected to the House for seven more two-year terms, serving from 1897 to 1913, until deciding not to run for re-election 16 years later in the summer of 1912. At the end of his congressional career, Brantley also served as a delegate to the
1912 Democratic National Convention, which convened in
Baltimore's
Fifth Regiment Armory. It was one of the most important political presidential nominating conventions in Democratic Party and American history. After a major battle through numerous ballots for the presidential nomination pitting
James Beauchamp ("Champ") Clark of
Missouri, the powerful
Speaker of the House, against
Woodrow Wilson, the progressive
Governor of New Jersey, Governor Wilson won the party's nomination and later went on to
win the presidency. After his time on
Capitol Hill ended, Brantley remained afterwards in Washington for another two decades to continue to practice law there. He died in that city in 1934, and was returned home to Georgia to be buried in
Blackshear Cemetery in the town of his birth. Congressman Brantley and/or his father Benjamin Daniel Brantley are considered to be the namesakes to
Brantley County, Georgia, one of the most recent counties to be established in the state. It was separated from three other surrounding counties in southeastern Georgia and organized in 1920. ==References==
