Thomas B. Bell (1850 – 1919) was an American Democratic politician who held several significant offices in Alabama state government during the late 19th and early 20th centuries.
Born in 1850, Bell hailed from Lowndes County, Alabama, where he began his political career. He first served in the Alabama House of Representatives from 1884 to 1886. Following his term in the House, he was elected to the Alabama Senate, where he represented his district from 1888 to 1892.
Bell's most prominent role was as the Secretary of State of Alabama. He was elected to this statewide office and served for a decade, from 1894 to 1904. His tenure as Secretary of State coincided with a tumultuous period in Alabama politics, marked by the rise of the Populist movement, significant debates over agrarian issues, and the eventual passage of the 1901 Alabama Constitution, which effectively disfranchised the majority of African American voters and many poor white voters. Bell died in 1919.
