The league folded in 1906 when the Scottish League's First Division expanded to 18 clubs.
Original members
The eight original members were Abercorn, Ayr Parkhouse (not a Scottish League side), Kilmarnock, Linthouse, Morton, Partick Thistle, Port Glasgow Athletic and St Mirren.
In 1907 a tournament was staged to determine which club would keep the championship shield for good. Clyde defeated Hamilton Accies in the final, 3–2 on aggregate over two legs.[1]
