Thomas A. Hendricks, American lawyer and politician, 21st Vice President of the United States (died 1885)

Thomas Andrews Hendricks was an American politician and lawyer from Indiana who served as the 16th governor of Indiana from 1873 to 1877 and the 21st vice president of the United States from March until his death in November 1885. Hendricks represented Indiana in the U.S. House of Representatives (1851–1855) and the U.S. Senate (1863–1869). He also represented Shelby County, Indiana, in the Indiana General Assembly (1848–1850) and as a delegate to the 1851 Indiana constitutional convention. In addition, Hendricks served as commissioner of the United States General Land Office (1855–1859). Hendricks, a popular member of the Democratic Party, was a fiscal conservative. He defended the Democratic position in the U.S. Senate during the American Civil War and Reconstruction era and voted against the Thirteenth, Fourteenth, and Fifteenth Amendments to the U.S. Constitution. He also opposed Radical Reconstruction and President Andrew Johnson's removal from office following Johnson's impeachment in the U.S. House.

The vice president of the United States is the second-highest ranking office in the executive branch of the U.S. federal government, after the president of the United States, and ranks first in the presidential line of succession. The vice president is also an officer in the legislative branch, as the president of the Senate. In this capacity, the vice president is empowered to preside over the United States Senate, but may not vote except to cast a tie-breaking vote. The vice president is indirectly elected at the same time as the president to a four-year term of office by the people of the United States through the Electoral College, but the electoral votes are cast separately for these two offices. Following the passage in 1967 of the Twenty-fifth Amendment to the US Constitution, a vacancy in the office of vice president may be filled by presidential nomination and confirmation by a majority vote in both houses of Congress.
