Basketball in Slovenia

Although in some parts of Yugoslavia basketball was played from the 1920s onwards, it came to the territories that are today part of Slovenia only during the Second World War. The first club was founded in Ljubljana as a basketball section of ŽŠK Hermes in 1943, when the city was under Italian administration. After the war, basketball was promoted mostly by students who came from the Belgrade Sports Institute and new clubs were soon founded in Ljubljana, Maribor, Murska Sobota, Celje and Lendava. The first postwar public match was played in February 1946 and the first Championship was held later that year, with Svoboda winning the first title. The Slovenian champion had the opportunity of competing for the Yugoslav Championship in the final tournament until 1949, when with the formation of the Basketball Federation of Yugoslavia an annual league called the federal league was established. It was joined by two best Slovenian teams Enotnost and Železničar, who later both played a major role in Yugoslav basketball. Enotnost, renamed Olimpija, won the Yugoslav league six times, while Železničar won one cup title.

On 15 January 1950 the Basketball Federation of Slovenia was founded as a section of the Yugoslav federation and home and away round-robin Republic league matches were established as a second or third tier of Yugoslav basketball. The Republic champion had the opportunity of promotion to the Yugoslav leagues and apart from Olimpija and Železničar also Slovan, ŽKK Maribor, Lesonit and Maribor 66 managed to play in the Yugoslav First Federal Basketball League. In 1950 Mirko Amon (Železničar), best scorer of yugoslav league that season, became the first Slovenian player in Yugoslavia national basketball team, later to be followed by many others. Slovenian players with most appearances for the national team were Ivo Daneu, Peter Vilfan, Jure Zdovc, Boris Kristančič and Aljoša Žorga. Slovenian players had important role when Yugoslavia won the 1970 FIBA World Cup in Tivoli Hall in Ljubljana, while they were also members of 1978 and 1990 World Championships' winning teams. Apart from men, women basketball was also popular with Iskra Delta Ježica being regular in Yugoslav women's league and many players becoming members of women's national team, the team who took part in four FIBA Women's EuroBasket tournament including 2023 in which the country will co-host alongside Israel.

After the Independence of Slovenia in 1991 national League and Cup competitions were formed on the basis of old republic structures. Slovenia became official members of FIBA on 10 January 1992 and the Slovenia national basketball team played their first official match against Croatia in May of that year.
