After the First World War finished, the club was again renamed, this time to Rawmarsh Athletic, but this name too would not last long as Rawmarsh Welfare was soon settled upon, and the club started to gain success on the pitch. They won the Association League for the first time in 1936, and three years later they secured a league and cup double by winning their second league title and the prestigious Sheffield & Hallamshire Senior Cup – beating Worksop Town in the final.
