About NK IB 1975 Ljubljana

NK IB 1975 Ljubljana is a Slovenian football club based in Ljubljana that was originally founded in 1975 as NK Ježica. The club spent its early decades competing mainly in lower regional leagues within the Yugoslav football system and later the Slovenian league structure. Over time it went through several reorganizations and name changes, eventually becoming known as NK Factor Ježica and later NK Interblock after a takeover and rebranding in the mid-2000s. This period marked the beginning of its rise through the national football pyramid.

The club experienced its most successful era in the 2000s after strong financial backing and restructuring. It reached the Slovenian top division and achieved notable success, including winning major domestic trophies. Under the Interblock name, the club won the Slovenian Cup twice in consecutive seasons and also secured the Slovenian Supercup. During this time, it also competed in European competitions, representing Slovenia in UEFA tournaments.

After 2010, the club went through further changes, including cooperation and partial mergers with other Ljubljana-based football projects. The senior team eventually withdrew from professional competition in 2012 due to organizational instability but was later re-established and continued playing in lower divisions. Today, NK IB 1975 Ljubljana operates mainly within the lower tiers of Slovenian football, focusing on rebuilding its structure and youth development.
