December 26 is Independence and Unity Day of Slovenia, commemorates the official proclamation of the Slovenian independence referendum on December 26, 1990.
Historically, the current territory of Slovenia was part of many different state formations, including the Roman Empire and the Holy Roman Empire, followed by the Habsburg Monarchy.
In October 1918, the Slovenes exercised self-determination for the first time by co-founding the internationally unrecognized “State of Slovenes, Croats and Serbs”, which merged that December with the Kingdom of Serbia into the Kingdom of Serbs, Croats and Slovenes (renamed Kingdom of Yugoslavia in 1929).
During World War II, Slovenia was occupied and annexed by Germany, Italy, and Hungary, with a tiny area transferred to the Independent State of Croatia, a Nazi puppet state.
Afterward, it was a founding member of the Federal People’s Republic of Yugoslavia, later renamed the Socialist Federal Republic of Yugoslavia, a communist state which was the only country in the Eastern Bloc not part of the Warsaw Pact.
In June 1991, after the introduction of multi-party representative democracy, Slovenia split from Yugoslavia and became an independent country.
Slovenia ,officially the Republic of Slovenia, is a nation state in southern Central Europe, located at the crossroads of main European cultural and trade routes. It is bordered by Italy to the west, Austria to the north, Hungary to the northeast, Croatia to the south and southeast, and the Adriatic Sea to the southwest.
