Who served as the only President of the Confederate States?

Jefferson Davis served as the only President of the Confederate States. During the American Civil War, he was appointed as the leader of the Confederacy when it was formed in 1861. His role involved overseeing the Confederate government's operations, making military decisions, and attempting to manage the various challenges faced by the South during the conflict. Davis had a background in politics and military service, which shaped his leadership during this tumultuous period.

In contrast, Robert E. Lee was a prominent general for the Confederate Army but did not hold a presidential role. Rutherford B. Hayes and Ulysses S. Grant were presidents of the United States after the Civil War, with their leadership occurring in the context of Reconstruction. Their involvement was unrelated to the Confederate government or its presidency.
