Up to season 1972–73, Scotland's rugby union clubs participated in what was known as an 'unofficial championship'. It provided very unbalanced competition: some clubs played more fixtures than others and some fixture lists provided stiffer opposition than others. The resulting league table at the end of each season gave a very unbalanced and difficult-to-comprehend set of results. Starting in season 1973–74, the
Scottish Rugby Union organised the full member clubs into six leagues. Though the SRU's administrators were often seen as backward looking, Scotland had a national league before England,
Wales or
Ireland. Since the advent of the leagues, the
Scottish Rugby Union and its member clubs have re-organised the competition several times, usually to change the number of teams. The current Regional Leagues are based more on political than physical geography. The Caledonia region covers a much larger area and more clubs but a smaller population. The East region is made up of the City of Edinburgh, the Lothians and the Borders, traditionally the strongest rugby playing regions. The West region is based on the old Strathclyde council region, from the South-West English border, through Ayrshire, Lanarkshire, Glasgow and suburbs North to Stirlingshire. The Caledonia Region covers the whole North of Scotland from Fife and Stirling, all the way to Orkney and Eilean Siar. It is sub-divided (in leagues 2 and 3) into Midlands, North and North-West. ==
