Biography
James Buchanan was born April 23, 1791. He built a long and accomplished career in public service before the presidency, serving as a U.S. Representative, Minister to Russia and later Great Britain, U.S. Senator from Pennsylvania, and Secretary of State under President Polk. He won the presidency in 1856, and his single term (1857β1861) was consumed by the deepening national crisis over slavery, as he largely sided with Southern interests and took a passive approach as several Southern states began seceding from the Union in the months following Lincoln's election in late 1860. He left office just weeks before the Civil War began, and is widely ranked by historians as one of the least effective presidents for his failure to address or prevent the coming conflict.
