Shirts from the Portuguese Primeira Liga

The Primeira Liga is the highest football league in Portugal's football system. Until 1999, the league was called Campeonato Nacional da Primeira Divisão and was then changed to the current name Primeira Liga.

Between the 1921/22 and 1937/38 seasons, the Portugal championship was played as a cup competition. A regular season was also played between 1934/35 and 1937/38. However, the champion of this competition did not become national champion, but league champion. From the 1938/39 season, the regular competition determines the national champion and there is a separate cup competition: Taça de Portugal. The national champion plays against the winner of the cup tournament (or the cup finalist if the double is won) for the Supertaça Cândido de Oliveira.
