25 June, Croatia: Statehood Day
The Republic of Croatia celebrates Statehood Day (Dan državnosti) every year on June 25 to commemorate the country’s declaration of independence from the then Socialist Federal Republic of Yugoslavia.
The Croatian parliament adopted the Declaration on independence after the referendum held on May 19th in 1991.
Slovenia declared independence from Yugoslavia at the same time, and also celebrates Statehood Day on June 25.
The Statehood Day used to be May 30, commemorating the day when the first post-Communist multi-party Parliament was constituted.
There was some controversy regarding which day is more suitable for the day of the statehood, but in the end June 25th prevailed as an official holiday.
