The reserve side were crowned champions of their league in 1939 before seeing the following season abandoned. 1975 league reconstruction With the end of hostilities in 1946, Rangers returned to play competitive football again with the reserve side featuring in the Scottish Reserve League. This was to continue unchanged for almost three decades until the first of many reconstructions were made to football in Scotland. SPL breakaway The formation of the Scottish Premier League in 1998, resulted in a significant change in youth team football in Scotland. The SPL began a league for members clubs youth players aged under-18. This was alongside the Reserve league, which had been revamped into a league primarily for under-21 players.

It attracted four investors from outside Rangers who have invested £1 million, with the club also putting up an initial £2.5 million. It led to Rangers F.C. being in the unfamiliar position of buying its own youth players from Rangers Youth Development Ltd. The Youth Development company owned the young players
