Croatia held a referendum on independence on 19 May 1991, in which the electorate—minus many Serbs, who chose to boycott it—voted overwhelmingly for independence with the option of confederate union with other Yugoslav states - with 83 percent turnout, voters approved the referendum by 93 percent. On 25 June 1991, Croatia and Slovenia both declared their independence from Yugoslavia. As the JNA attempted unsuccessfully to suppress Slovenia's independence in the short Slovenian War, clashes between revolting Croatian Serbs and Croatian security forces broke out almost immediately, leaving dozens dead on both sides. Serbs were supported by remnants of the JNA (whose members were now only from Serbia and Montenegro), which provided them weapons. Many Croatians fled their homes in fear or were forced out by the rebel Serbs. The European Union and United Nations unsuccessfully attempted to broker ceasefires and peace settlements.
