Slovenian referendum on independence from Yugoslavia.
The Eastern European country had joined the Socialist Federal Republic of Yugoslavia as a socialist republic state in 1945. Actual independence for the country did not occur until 25 June, 1991, when the Slovenians rejected Yugoslavian interference in the form of a 10-day war that ended on July 7, 1991. A new constitution for the country came into force on December 23, 1991.
