About Day of Uprising Against the Occupation

Slovenia observes the Day of Uprising Against the Occupation on April 27.

The Government of Slovenia lists it as a national holiday and, unlike the specifically marked exceptions on the national-holidays page, a work-free day.

Why Day of Uprising Against the Occupation matters

The observance remembers resistance to occupation during the Second World War in Slovenia.

Its official history includes an April 1941 political-resistance meeting, later Liberation Front identity, and a post-independence renaming; these layers are kept separate rather than compressed into a single origin claim.

History of Day of Uprising Against the Occupation

Government historical material places the founding meeting of the Anti-Imperialist Front on April 26, 1941; the organization later became the Liberation Front of the Slovene Nation after Germany attacked the Soviet Union in June 1941.

The same government history explains that April 27 became established in public memory as the founding date even though the meeting is documented as having taken place on April 26.

Before Slovenian independence, April 27 was known as the Day of the Liberation Front (Day of the OF).

The 1991 Slovenian public-holidays law lists April 27 under the current name, Day of Uprising Against the Occupation, and makes the listed national holidays work-free unless otherwise provided.
