Hamburger Sport-Verein e.V. [hamˈbʊʁɡɐ ˌʃpɔʁt fɛɐ̯ˈʔaɪ̯n], commonly known as Hamburger SV, Hamburg or HSV [haː ʔɛs ˈfaʊ̯], is a German sport club based in Hamburg, its largest branch being its football department. Although the current HSV was founded in June 1919 from a merger of three earlier clubs, it officially traces its origin to 29 September 1887 when the first of the predecessors, SC Germania, was founded. HSV's football team has the unique distinction of having played continuously in the top tier of the German football league system since the end of World War I. It is the only team that has played in every season of the Bundesliga since its foundation in 1963, at which time the team was led by German national captain Uwe Seeler.
HSV has won the German national championship six times, the DFB-Pokal three times and the 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. Their outstanding player was German national star Felix Magath. To date, HSV's last major trophy was the 1986–87 DFB-Pokal.
