In his "House Divided" speech, Abraham Lincoln accused Supreme Court Chief Justice Roger Taney, Franklin Pierce, James Buchanan and Senator Stephen Douglas of a conspiracy to perpetuate slavery in the United States. According to Lincoln, this conspiracy took form in the 1857 Supreme Court case of Dred Scott v. Sandford, which excluded African Americans from U.S. citizenship.
