Croat opposition to the new régime was strong and, in late 1932, the Croatian Peasant Party issued the "Zagreb Manifesto" which sought an end to Serb hegemony and dictatorship. The government reacted by imprisoning many political opponents including the new Croatian Peasant Party leader Vladko Maček. Despite these measures, opposition to the dictatorship continued, with Croats calling for a solution to what was called the "Croatian question". In late 1934, the King planned to release Maček from prison, introduce democratic reforms, and attempt find common ground between Serbs and Croats.
