The club was founded as Odd in 1917, but were not allowed to play amateur league matches until 1928, when they took the present name. They reached the League of Norway in 1937–38, but fell to lower divisions from the 1940s. The club moved to Lerkendal in 1957 and their first title was the 1960 Cup, resulting in the first participation in a UEFA tournament. It was first during the 1960s that RBK established itself as Trondheim's primary football team. From 1967, RBK qualified for the lop league, where they, except for 1978, have remained since. Three league titles were taken between 1967 and 1971. The team's golden era started with the 1985 league title, and from 1991 through 2004 the team won 13 consecutive titles, 10 under manager Nils Arne Eggen. The period also saw 12 participation in the group stage of Champions League and reaching the quarter-finals in 1996–97.
