Union cavalrymen arrested former Confederate presidentnear Irwinville, Georgia, on May 10, 1865. Davis was taken into custody as a suspect in the assassination of United States president Abraham Lincoln, but his arrest and two-year imprisonment at in Virginia raised significant questions about the political course of Reconstruction (1865–1877). Debate over Davis’s fate tended to divide between those who favored a severe punishment of the former Confederate political leaders and those who favored a more conciliatory approach. When investigators failed to establish a link between Davis and the Lincoln assassins, the U.S. government charged him instead with treason. U.S. president Andrew Johnson’s impeachment hearings delayed the trial, however, and in the end the government granted Davis amnesty.
