a 5– 0 win over North Funen side Start Otterup from Otterup. In the summer of 1915, the club changed its name to Svendborg Boldklub (SB). By winning the local rounds organised by the local football federation, the Svendborg-based club managed to qualify as FBU's only representative to participate in the 1925–26 season of the Denmark Tournament, a Danish FA-organised club football tournament between the championship clubs from each of the six regional football associations. Here, Svendborg Boldklub only made one appearance, on 30 May 1926, a match which was played in Vejle during the second round of the tournament DBU Jutland (JBU)'s representative Horsens fS, which they lost 3—1. In 1954, another Svendborg-side was founded, Kammeraternes Boldklub (KB), who became a direct competitor to Svendborg Boldklub, a rivalry emanating from the clubs' table tennis departments. KB was formed through a merger between the sports clubs Fremad (Est. 1938) and Frem (Est. 1926 as Arbejdernes Boldklub (AB), name change to Frem in 1932), and had its home ground at Skovsbovej Stadium. Svendborg Boldklub had for years been close to reaching promotion to the 3rd Division (then Denmark's third highest tier) via its predecessor Kvalifikationsturneringen (Qualification Tournament; popularly called the "4th Division", today known as the Denmark Series). Meanwhile, Kammeraternes Boldklub only competed in the regional divisions, the Funen Series at the fifth highest tier. Between 1961 and 1962, the "bourgeoisie" club Svendborg Boldklub and the so-called working-class side Kammeraternes Boldklub merged and continued under the new name, Svendborg forenede Boldklubber (Svendborg fB or SfB), keeping Svendborg Boldklub's original founding date. In 1970, the new sports facility, Høge Bøge Stadium, was made the club's new official home ground. Three years after uniting with the local rivals, the merger club managed to qualify for the Danish divisions for the first time in Svendborg fB's history by securing promotion to the Danish 3rd Division ahead of the 1964 season. Divisional status was lost after relegating to the newly created Denmark Series, the fourth tier, which was the tier below the three divisions, where the club played in the 1967, 1968 and 1970 seasons. In 1969, Richard Møller Nielsen was appointed head coach for Svendborg fB. Under him, the side claimed the Danish 3rd Division West championship and reached promotion to the Danish 2nd Division in the 1972 season, the first time appearance at this level in club history. Møller Nielsen would later coach
