There have been three referendums in modern Croatia: Croatian independence referendum, Croatian European Union membership referendum and Marriage definition referendum, and in all three majority voted in favor. There have been four other public initiatives to collect the support of 10 percent of voters for a referendum, none of which were successful: concerning Croatian cooperation with the International Criminal Tribunal for the former Yugoslavia, concerning accession of Croatia to NATO in 2008, concerning Arbitration Agreement on Croatian-Slovenian border issues in 2009, and concerning Labour Act in 2010.
