Established in 1890, the Scottish Professional Football League (SPFL) stands as the bedrock of footballing competition in Scotland. This overarching league structure oversees several divisions, with the Scottish Premiership at its summit, where clubs compete for the coveted league title and the chance to represent Scotland in European competitions.

The Scottish Premiership, the top tier of Scottish football, operates on a system of promotion and relegation and comprises 12 teams. The league season unfolds in a double round-robin format, with each team facing its counterparts twice – once at home and once away. This competitive structure, marked by fierce rivalries and passionate fanbases, is a hallmark of Scottish football.

Throughout its history, certain clubs have stood out as dominant forces within the Scottish Premiership. Celtic FC and Rangers FC, two of the most successful and storied clubs in Scottish football, have consistently vied for supremacy, accumulating numerous league titles between them. Their head-to-head clashes, known as the Old Firm derby, add an extra layer of intensity and excitement to the league.

The list of past Scottish Premiership champions reflects the enduring competition between Celtic and Rangers, as well as occasional breakthroughs by other ambitious clubs. The cyclical nature of success in the league contributes to the unpredictability and drama that fans relish each season.

The Scottish football calendar aligns with the European schedule, with the Premiership season typically commencing in August and concluding in May. This allows Scottish clubs to participate in European competitions, adding to the prestige of the league and providing opportunities for exposure on the continental stage.
