Albin Prepeluh was a Slovenian left wing politician, journalist, editor, political theorist and translator. Before World War I, he was the foremost Slovene Marxist revisionist theoretician. After the War, he became one of the most persistent advocates of Slovenian autonomy within the Kingdom of Yugoslavia, and, together with Dragotin Lončar, the ideologist of the democratic reformist faction of Slovenian Social Democrats. In the late 1920s, he evolved towards agrarianism. He was also known under the pseudonym Abditus.
