Sovereignty Day (Slovenia)
holiday in Slovenia

Sovereignty Day (Slovene: dan suverenosti) is a public holiday in Slovenia, celebrated on 25 October. It commemorates one of the key events in the process of attaining independence, namely withdrawal of the last Yugoslav People's Army (JNA) soldier from the territory of present-day Slovenia. It is a designated state holiday, but not a work-free day.
Background
The Ten-Day War, a civil war, started in the former Yugoslavia on 27 June 1991 between the Yugoslav army and the Slovenian Territorial Defence, ending on 7 July with Slovenia's decisive victory and Slovenia becoming independent. In the Brioni Agreement signed by both parties, Slovenia agreed to postpone its independence by three months and the Yugoslav military was allowed to leave Slovenian territory in stages, with a deadline of the end of October. The last Yugoslav army soldier left around midnight of 25 October 1991, the day now declared as "Sovereignty Day".
Date issue
The key event, the departure of the ship with the last remaining JNA soldiers from the Port of Koper, actually happened on the night of 25 October 1991. Therefore, some consider 26 October to be the real anniversary. However, the last two ships that were still moored in the port at midnight were flying foreign flags, and thus constituted foreign territory according to admiralty law. All the troops on board therefore left the Slovene territory as soon as they boarded – which was before midnight.
This brief starts where responsible research should: with the source description of “Sovereignty Day (Slovenia)” as holiday in Slovenia. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as holiday in Slovenia. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q20820628. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1991.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
