John C. Breckinridge, American lawyer and politician, 14th Vice President of the United States, Confederate States general (born 1821)

John Cabell Breckinridge was an American politician who served as the 14th vice president of the United States, with President James Buchanan, from 1857 to 1861. Assuming office at the age of 36, Breckinridge is the youngest vice president in U.S. history. Breckinridge was also the Southern Democratic candidate in the 1860 presidential election, which he lost to Republican Abraham Lincoln.

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.

The Confederate States of America (CSA), also known as the Confederate States (C.S.), the Confederacy, or the South, was an unrecognized breakaway republic in the Southern United States from 1861 to 1865. It comprised eleven U.S. states that declared secession: South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, Texas, Virginia, Arkansas, Tennessee, and North Carolina. These states fought against the United States during the American Civil War.
