Хайдер СФ

Small town on the big stage

The team is known popularly as kleiner HSV (en: Little HSV), a play on the name of better known Hamburger SV. They represented the smallest town competing in top-flight German competition in the regional Oberliga Nord (I) in 1956–57 and 1960–61 against the likes of larger clubs including Hamburger SV, Hannover 96, Werder Bremen, and FC St. Pauli. The club's appearances in the top flight were brief, but they were enthusiastically supported, regularly drawing large crowds. The highlight of Heider SV's 1956–57 season was a 2–0 victory over Hamburger SV before a crowd of 12,000, an attendance record that still stands to this day.

In 1951, 1953, and 1955, Heider SV took part in the country's amateur championship with their best result coming as an advance to the semi-finals in 1955 where they were lost 3–1 to Sportfreunde Siegen. The club also made failed attempts to return to Oberliga play in 1954, 1958, 1959, and 1962.

Post-Bundesliga

After the formation of the Bundesliga, Germany's first fully profession league, in 1963, Heider SV became part of the Amateurliga Schleswig-Holstein (III) after failing to qualify for the new Regionalliga Nord (II). The team did eventually win its way to the Regionalliga for a single season turn in 1968–69, and again for a four-season stint in 1970–74. After slipping down through the Amateurliga, Heider SV became a fixture in fourth-tier play in the Landesliga Schleswig-Holstein (1975–78), the Verbandsliga Schleswig-Holstein (1978–94), and the Oberliga Hamburg/Schleswig-Holstein (1994–2004), before finally falling to fifth-tier play in the Verbandsliga Schleswig-Holstein in 2004. Although generally a mid-table finisher, Heider SV continued to field competitive sides through the years, earning four second-place results, as well as a Verbandsliga Schleswig-Holstein (IV) title in 1982–83.

The club has made occasional appearances in competition for the DFB-Pokal (German Cup), but has never advanced out of the opening round.

After losing a promotion round playoff to Arminia Hannover in 1997, the club struggled, delivering poor performances, losing the support of its fans and sponsors, and facing financial problems. Their situation has since stabilized and they currently play as a lower table side in the Schleswig-Holstein-Liga (V), finishing 10th in the 2013–14 season.
