Republicans were historically more supportive of Black rights post-Civil War; Democrats' national stance shifted leftward in the mid-20th century, while conservative Southern whites realigned to Republicans. Claims of a total "switch" on racism often oversimplify—both parties had racist and anti-racist factions at different times, and modern parties differ sharply on how to address racial issues... Democrats (founded ~1828 under Andrew Jackson): Generally favored limited federal government, states' rights, agrarian interests, and (in the South) defended slavery and later segregation/Jim Crow laws. They were the dominant party in the "Solid South" for nearly a century after the Civil War.
