"As Reconstruction progressed, resistance grew to Republican attempts to assist freed slaves to attain full citizenship and economic opportunities. Many Southern whites resisted such efforts politically with membership in the Democratic Party and violently through groups such as the Ku Klux Klan. As Democrats gradually regained control of Southern state governments, Douglass advised blacks to remain loyal to the party of Lincoln because ‘the Republican party is the deck, all outside is the sea.’"
