Västerås Rugbyklubb were founded on 18 April 1948 on initiative by Karl Wolgert Nilsson after he had learnt to play in the United States.[1] They immediately advanced to the Swedish Championship final, which they lost. November the following year, 1949, they managed to qualify again and won to IK Göta, 10–0.[1][2]
The club later disbanded in 1955 but restarted in the 1970s, then attracting former Harlequins F.C. player Tim Rutter who was working in Västerås.[1] They again restarted in 2010 after 20 years hiatus.[3]
