The protests were initially aimed against Minister of War Veterans deputy Bojan Glavašević and minister Predrag Matić himself, however the protesters subsequently changed their demands and started demanding the resignation of left wing prime minister Zoran Milanović and then president Ivo Josipović.The protests escalated in May 2015 when a group of protesters breached the riot police cordons in Zagreb Upper Town and baricaded themselves inside St. Mark Church, where they again clashed with the police.
