According to Columbia University historian Eric Foner, became "a military force serving the interests of the Democratic Party." Nor is there reference to University of North Carolina historian Allen Trelease's description of the Klan as the "terrorist arm of the Democratic Party."
Democrats opposed the 13th, 14th and 15th amendments to the Constitution. The 13th banned slavery. The 14th effectively overturned the infamous 1857 Dred Scott decision (made by Democratic pro-slavery Supreme Court justices) by guaranteeing due process and equal protection to former slaves. The 15th gave black Americans the right to vote.
Democrats opposed the Civil Rights Act of 1866. It was passed by the Republican Congress over the veto of President Andrew Johnson, who had been a Democrat before joining Lincoln's ticket in 1864.

Democrats' 1904 platform, which devotes a section to "Sectional and Racial Agitation," claiming the GOP's protests against segregation and the denial of voting rights to blacks sought to "revive the dead and hateful race and sectional animosities in any part of our common country," which in turn "means confusion, distraction of business, and the reopening of wounds now happily healed."
four Democratic platforms, 1908-20, that are silent on blacks, segregation, lynching and voting rights as racial problems in the country mount. By contrast the GOP platforms of those years specifically address "Rights of the *****" (1908), oppose lynching (in 1912, 1920, 1924, 1928) and, as the New Deal kicks in, speak out about the dangers of making blacks "wards of the state."
Democratic Convention of 1924, known to history as the "Klanbake." The 103-ballot convention was held in Madison Square Garden. Hundreds of delegates were members of the Ku Klux Klan, the Klan so powerful that a plank condemning Klan violence was defeated outright. To celebrate, the Klan staged a rally with 10,000 hooded Klansmen in a field in New Jersey directly across the Hudson from the site of the convention. Attended by hundreds of cheering convention delegates, the rally featured burning crosses and calls for violence against African-Americans and Catholics.
