why did southern democrats walk out of the democratic convention
Dixiecrat After Roosevelt died, the new president Harry Truman established a highly visible President's Committee on Civil Rights and issued Executive Order 9981 to end discrimination in the military in 1948. A group of Southern governors such as Strom Thurmond of South Carolina and Fielding L. Wright of Mississippi met to consider the place of Southerners within the Democratic Party. After a tense meeting with DNC chairman and Truman confidant J. Howard McGrath, the Southern governors agreed to convene their own convention in Birmingham if Truman and civil rights supporters emerged victorious at the 1948 Democratic National Convention.[9] In July, the convention re-nominated Truman and adopted a plank proposed by Northern liberals led by Hubert Humphrey calling for civil rights; 35 southern delegates walked out. The move was on to remove Truman's name from the ballot in the southern United States. This political maneuvering required the organization of a new and distinct political party, which the Southern defectors from the Democratic Party chose to brand as the States' Rights Democratic Party.
Reconstruction Era Elected in 1868, Republican President Ulysses S. Grant supported Congressional Reconstruction and enforced the protection of African Americans in the South through the use of the Enforcement Acts passed by Congress. Grant used the Enforcement Acts to effectively combat the Ku Klux Klan, which was essentially wiped out (although a new incarnation of the Klan eventually would again come to national prominence in the 1920s), but was unable to resolve the escalating tensions inside the Republican party between the northerners on the one hand, and those Republicans originally hailing from the South on the other (this latter group would be labelled "Scalawags" by those opposing Reconstruction). Meanwhile, "Redeemers", self-styled Conservatives (in close cooperation with a faction of the Democratic Party) strongly opposed reconstruction.[4] They alleged widespread corruption by the Carpetbaggers, excessive state spending and ruinous taxes. Meanwhile, public support for Reconstruction policies, requiring continued supervision of the South, faded in the North, largely due to concerns over the Panic of 1873. The Democrats, who strongly opposed Reconstruction, regained control of the House of Representatives in 1874. In 1877, as part of a Congressional bargain to elect Republican Rutherford B. Hayes as president following the close 1876 presidential election, U.S. Army Troops were removed from the South, ending Reconstruction and allowing Democrats to return to power.
