Already at a young age, Prepeluh became influenced by
Marxist and
autonomist ideas. In 1902, he corresponded with the German Marxist theoretician
Karl Kautsky on the possibilities to activate the
peasantry in favour of
socialism. The same year, he founded the journal
Naši zapiski ('Our Notes'), in which he propagated radical socialist reformism. The journal soon became the herald of young Slovene reformist
Social Democrats, which included
Anton Dermota,
Dragotin Lončar, and
Josip Ferfolja. In 1904, Prepeluh became a member of the
Yugoslav Social Democratic Party. He soon entered in conflict with the party's mainstream. Prepeluh rejected the official
Austromarxist orientation of the party, and soon entered in confrontation with the party leader
Etbin Kristan. Differently from Kristan, Prepeluh endorsed the
Bersteinian critique of
Marx; he also supported the quest for
territorial autonomy of the
South Slav peoples against the official Social Democrat support for a purely
cultural autonomy. During this time, Prepeluh became a close friend and collaborator of the Social democratic author
Ivan Cankar. They both shared a similar personalist and autonomist vision of socialism, and they both opposed the gradual cultural and linguistic assimilation of all South Slavs, officially supported by the Yugoslav Social Democratic Party. After 1908, Prepeluh developed a friendly relationship with the
Christian Social politician
Janez Evangelist Krek, who unsuccessfully tried to persuade him to leave the Social Democratic Party and join the
Slovene People's Party. Prepeluh remained in the Social Democratic Party, but in the following years he grew closer to
Christianity. In 1910, he rose in defense of the "popular faith" against the prevailing
Anti-Catholicism of
Slovene liberals and social democrats, and criticised the prolongation of the
Kulturkampf in the
Slovene Lands. In 1917, Prepeluh became the leader of the internal opposition against the main current of the Yugoslav Social Democratic Party, which continued to put the social question before the issue of national emancipation. In 1918, with the creation of the
State of Slovenes, Croats and Serbs, Prepeluh rose to the leadership of the party. He was the leader of its right wing in a sharp confrontation against the left wing, represented by
Dragotin Gustinčič,
Anton Štebi and
Rudolf Golouh. He was in favour of collaboration with the
Democratic Party and supported the social-liberal coalition government of
Ljubomir Davidović. After the Yugoslav Social Democratic Party, which was a preponderately Slovenian organization, merged with the
Centrumaši and formed the
Socialist Party of Yugoslavia in 1921, Prepeluh became marginalized. In 1920, he and
Dragotin Lončar re-founded the journal
Naši zapiski. They both opposed the
centralist program of the new unified Yugoslav Socialist party, and called for a
territorial autonomy of Slovenia within Yugoslavia. In 1921, he was one of the proponents of the influential
Autonomist Declaration, in which the majority of the most important Slovene intellectuals voiced their support for Slovenian autonomy. In 1924, Prepeluh and Lončar founded the Slovenian Agrarian Labour Party, which soon merged with the small Slovenian Republican Party into the
Slovenian Labour Agrarian Republican Party. The party established close connections with the
Croatian Peasant Party. In 1926, it merged with the
Independent Agrarian Party, into the
Slovenian Peasant Party, of which Prepeluh became the main ideologist. After the party was dissolved with the establishment of the dictatorship of king
Alexander I of Yugoslavia in 1929, Prepeluh retrieved from public life. == Work ==
