However, despite its name, it corresponds to today's Portuguese Cup (Taça de Portugal) and was held in a knock-out basis.

[1] From the 1938–39 season on, Campeonato de Portugal was named Taça de Portugal, and Campeonato da Liga was named National Championship of the First Division, usually called First Division (Primeira Divisão).

Benfica, with 38 titles, have been crowned champions more times than any other club and dominated the league during the 1960s and 1970s.

The Double, called Dobradinha in Portuguese, means winning the Primeira Liga and the Taça de Portugal in the same season.

The Quadruple, called Quadriplete in Portuguese, refers to winning 4 titles in the same season.
