The Đapić family had a history of supporting the old Croatian Party of Rights, and later the Ustaše regime.
Đapić lost his mother in a car crash when he was a teenager,[2] so he had to do manual labour while studying law at Osijek University.
He was one of the party's organizers in Osijek, but he was expelled after a short time for using the "Za dom spremni" salute.
In 2000, this time in coalition with Croatian Christian Democratic Union (HKDU), HSP kept four Parliament seats.
HSP continues to oppose the existence of the Hague War Crimes Tribunal, to hold eurosceptic views and is socially very conservative.
Đapić was replaced as the president of the party at the November 2009 convention by Daniel Srb.
[4] In 2013, he briefly returned to active politics by announcing his intention to run for the mayor of Osijek again, but was expelled from the HSP shortly thereafter.
