Joshua L. Martin, born in 1799 in Blount County, Tennessee, established a foundational legal career in Maryville before relocating to Alabama. He passed the bar in the 1820s and practiced law in Athens. Martin's political career began with his election to the United States Congress in 1835 as a Jacksonian Party member, later transitioning to the Democratic Party. He served as Alabama's 12th governor from 1845 to 1847, during which he managed significant state transitions, including the relocation of the state capital and the dissolution of the state bank, an action he opposed. Martin later served another term in the state legislature in 1853.

Joshua L. Martin's political identity is marked by a blend of steadfast traditionalism and strategic adaptability. Despite his initial affiliation with the Jacksonian Party and later the Democratic Party, Martin's independent gubernatorial run in 1845 underscores a willingness to defy party orthodoxy. His opposition to the dissolution of the state bank, despite its occurrence during his governorship, highlights a tension between his ideological convictions and political pragmatism. Martin's tenure during the U.S.-Mexico War further complicates his foreign policy stance, revealing a potentially complex approach to national versus regional interests.
