The Declaration of Constitutional Principles (known informally as the Southern Manifesto) was a document written in February and March 1956, during the 84th United States Congress, in opposition to racial integration of public places. The manifesto was signed by 19 US Senators and 82 Representatives from the South. The signatories included the entire Congressional delegations from Alabama, Arkansas, Georgia, Louisiana, Mississippi, South Carolina, and Virginia, most of the members from Florida and North Carolina, and several members from Tennessee and Texas. All of them were from former Confederate states. Ninety-nine were Democrats; two were Republicans. The Manifesto was drafted to counter the landmark Supreme Court 1954 ruling Brown v. Board of Education, which determined that segregation of public schools was unconstitutional. School segregation laws were some of the most enduring and best-known of the Jim Crow laws that characterized the Southern United States at the time. "Massive resistance" to federal court orders requiring school integration was already being practiced across the South, and was not caused by the Manifesto. Senator J. William Fulbright of Arkansas had worked behind the scenes to tone down the original harsh draft. The final version did not pledge to nullify the Brown decision nor did it support extralegal resistance to desegregation. Instead, it was mostly a states' rights attack against the judicial branch for overstepping its role. The Southern Manifesto accused the Supreme Court of "clear abuse of judicial power" and promised to use "all lawful means to bring about a reversal of this decision which is contrary to the Constitution and to prevent the use of force in its implementation." It suggested that the Tenth Amendment should limit the reach of the Supreme Court on such issues. Senators led the opposition, with Strom Thurmond writing the initial draft and Richard Russell the final version. The states of Delaware, Maryland, West Virginia, Kentucky, and Missouri had been border states during the Civil War (i.e. slave states that remained in the Union). Oklahoma was not then a state but Indian Territory had been settled primarily by white Southerners and by Native Americans under federal removal policy, and at least 7,860 Native Americans from Indian Territory enlisted in the Confederate States Army and most Indian Territory tribal leaders aligned with the Confederacy. Prior to the Brown v. Board decision, all required segregation in their public school systems. Nonetheless, none of the 12 U.S. Senators or 39 U.S.
