The Oberliga Hamburg, sometimes referred to as Hamburg-Liga, is the highest league in the German state of Hamburg, incorporating some of its surrounding districts. It is one of fourteen Oberligen in German football, the fifth tier of the German football league system. Overview 1945–1963 The league was re-formed in 1945 as Stadtliga Hamburg (English: Hamburg City League) by thirteen clubs, in the newly recreated state of Hamburg which was then part of the British occupation zone in Germany. The very first league in the Hamburg & Altona area had been inaugurated as early as 1895. In its first two seasons, the league was actually the first tier of the German league system for Hamburg, holding clubs like the Hamburger SV and FC St. Pauli in its ranks. From 1947, the Hamburg-Liga was a feeder league to the Oberliga Nord which its champion had the option of promotion to. Promotion had to be achieved through a play-off with teams from the Amateurligen of Lower Saxony, Bremen and Schleswig-Holstein. As such, the league was by then the second tier of the northern German league system. The league was renamed Verbandsliga Hamburg (English: Hamburg FA League), and split into two groups of ten teams, the Alsterstaffel and Elbestaffel, named after the two main rivers in Hamburg. The top four clubs of the 1946–47 season left the league for the new Oberliga Nord, those clubs being the Hamburger SV, FC St. Pauli, Concordia Hamburg and Victoria Hamburg. Traditionally, the league also accommodated clubs from neighboring Lower Saxony and Schleswig-Holstein (which it still does today), like Lüneburger SK and VfL Stade. The two divisions were increased in strength to twelve clubs each in 1949. The year after, the league was reunited in one single division with sixteen clubs. It received the new name of Amateurliga Hamburg. The league operated on a strength of sixteen for most of the coming seasons. 1963–1974 In 1963, with the introduction of the Bundesliga, the disbanding of the Oberliga Nord and the formation of the Regionalliga Nord, the league fell to tier three and was again renamed, now Landesliga Hamburg (English:Hamburg State League), but remained unchanged otherwise, with sixteen clubs as its strength. The champion of Hamburg continued to have to play-off for promotion, now to the Regionalliga, with the same opposition as before. From 1970, the number of leagues below the Hamburg–Liga was reduced from three to two, resulting
