The governor of Georgia is the head of government of Georgia and the commander-in-chief of the state's military forces. The current officeholder is Republican Brian Kemp, who assumed office on January 14, 2019. There have officially been 77 governors of the State of Georgia, including 11 who served more than one distinct term (John Houstoun, George Walton, Edward Telfair, George Mathews, Jared Irwin, David Brydie Mitchell, George Rockingham Gilmer, M. Hoke Smith, Joseph Mackey Brown, John M. Slaton and Eugene Talmadge, with Herman Talmadge serving two de facto distinct terms). The longest-serving governors are George Busbee, Joe Frank Harris, Zell Miller, Sonny Perdue and Nathan Deal, each of whom served two full four-year terms; Joseph E.
