Portuguese Volleyball First Division
The Portuguese Volleyball First Division (Portuguese: "Campeonato Nacional de Voleibol – I Divisão") is the top men's volleyball league in Portugal. The competition, which is organised by the Portuguese Volleyball Federation, was called Honor Division (Divisão de Honra) in 1983–84 and 1986–88. Between 1997 and 2011, the League was divided into two different series, A1 and A2. Since the 2014–15 season, the competition's champions are called "Elite Champions", while the "First Division Champion" title is disputed between the 4 losers of the play-off's first round.
