1 Jan 1862 Jahr - 1862 - In September of 1862, Lincoln suspended habeas corpus, a right guaranteed by the Constitution, in a direct display of executive power unprecedented at the time. Wartime dissenters were prosecuted under martial law without the right to a trial as was (and is) the law in the United States. The suspension of habeas corpus served to discourage dissent in the Union, but was a marked change toward a nation that would in the future have conflicts over the relationship between freedom and security.
