Hamburger SV, or HSV for short, is a German sports club based in Hamburg, with its largest branch being its football section. Up until the 2017–18 Bundesliga season, which found the team relegated for the first time in history, HSV’s football team had the distinction of being the only team that had played continuously in the top tier of the German football league system since the founding of the club at the end of World War I. It was subsequently the only team that had played in every season of the Bundesliga since its foundation in 1963. Hamburger SV has won the German national championship six times, the DFB-Pokal three times and the former League Cup twice. The team’s most successful period was from the mid-1970s until the mid-1980s when, in addition to several domestic honours, they won the 1976–77 European Cup Winners’ Cup and the 1982–83 European Cup. To date, HSV’s last major trophy was the 1986–87 DFB-Pokal.
