The KKK wasn't the outgrowth of a move by the Democratic party, but by a violent subgroup of Southern Democrats....very separate from, and in fundamental conflict with, Northern Democrats. The 2 groups had fought each other in the Civil War, and the southern group wanted to restore what they had lost. (And they weren't just anti-Black, but anti-Jewish. My mother, who was born in 1917, experienced that first-hand as a child in Newport News, VA.)

"...the Ku Klux Klan was formed in Pulaski, Tennessee, in 1865. Originally founded as a social club for former Confederate soldiers, the Klan evolved into a terrorist organization.... By 1868, the Klan had evolved into a hooded terrorist organization that its members called "The Invisible Empire of the South." The reorganized Klan's first leader, or "Grand Wizard," was Nathan Bedford Forrest, who had been a Confederate general during the Civil War."

And this northern/southern Democratic split formalized, although it ultimately repaired.
"During the Progressive Era, which spanned the turn of the century, the Democrats saw a split between its conservative and more progressive members. As the Democratic nominee for president in 1896, William Jennings Bryan advocated for an expanded role of government in ensuring social justice. Though he lost, Bryan's advocacy of bigger government would influence the Democratic ideology going forward..... Roosevelt's reforms raised hackles across the South, which generally didn't favor the expansion of labor unions or federal power, and many Southern Democrats gradually joined Republicans in opposing further government expansion.

Then in 1948, after President Harry Truman (himself a Southern Democrat) introduced a pro-civil rights platform, a group of Southerners walked out of the party's national convention. These so-called Dixiecrats ran their own candidate for president (Strom Thurmond, governor of South Carolina) on a segregationist States Rights ticket that year; he got more than 1 million votes.

Most Dixiecrats returned to the Democratic fold, but the incident marked the beginning of a seismic shift in the party's demographics. At the same time, many Black voters who had remained loyal to the Republican Party since the Civil War began voting Democratic during the Depression, and would continue to do so in greater numbers with the dawn of the civil rights movement."
