3. Liga Süd-West

[1] The league was formed after the 2009-10 season, with the purpose of creating a more competitive level of play for the rugby clubs in Southern Germany above the Regionalligas.

One was the RC Mainz, which was relegated from the 2nd Bundesliga at the end of the 2009-10 season, while, of the other eight, one came from the Regionalliga Bavaria, two from Hesse, one from Rhineland-Palatinate, one from Baden-Württemberg and three from North Rhine-Westphalia.

[1] For the 2011-12 season, the league was scheduled to be expanded to at least twelve teams in two regional divisions,[1] but started play with eleven clubs instead.

After the first round, the reserve team of RG Heidelberg joined the competition, thereby equaling both divisions in the number of clubs to six.

[4] In 2012-13 the league once more started out with eleven teams but two of those were removed from competition after missing fixtures, Grashof RC Essen and SC Neuenheim II.
