The league was created in 1947 as the highest level of football in the newly created state of North Rhine-Westphalia, then part of the British occupation zone. It replaced the various Gauligas, which had existed until 1945 in the region:
The Oberliga West was formed from thirteen clubs from the Landesligas Niederrhein, Mittelrhein and Westfalen. The Landesligas remained the second tier of football in the West until 1949, when the 2. Oberliga West was formed.
With the reintroduction of the German championship in 1948, the winner and runners-up of the Oberliga West went on to the finals tournament with the other Oberliga champions. The Oberliga West, together with the Oberliga Süd, were the strongest of the five Oberligas, winning six German titles each in the Oberliga period from 1948 to 1963.
With the introduction of the Bundesliga, five teams from the Oberliga West were admitted to the new Bundesliga. The remaining clubs went to the new Regionalliga West, one of five new second divisions.
The qualifying system for the new league was fairly complex. The league placings of the clubs playing in the Oberligen for the last ten seasons were taken into consideration, whereby results from 1952 to 1955 counted once, results from 1955 to 1959 counted double and results from 1959 to 1963 triple. A first-place finish was awarded 16 points, a sixteenth place one point. Appearances in the German championship or DFB-Pokal finals were also rewarded with points. The five Oberliga champions of the 1962-63 season were granted direct access to the Bundesliga. All up, 46 clubs applied for the 16 available Bundesliga slots.
Following this system, by 11 January 1963, the DFB announced nine fixed clubs for the new league and reduced the clubs eligible for the remaining seven places to 20. Clubs within the same Oberliga that were separated by less than 50 points were considered on equal rank and the 1962-63 placing was used to determine the qualified team.[1]
All Oberliga West clubs except TSV Marl-Hüls applied for Bundesliga membership. Borussia Dortmund, 1. FC Köln and FC Schalke 04 qualified early. Meidericher SV and Preußen Münster qualified even though both clubs had less points than Alemannia Aachen. Aachen finished fifth, Meidericher SV came in fourth and Preußen Münster earned a third-place finish in 1962–63.[2]
