Rugby-Bundesliga
The Rugby-Bundesliga is the highest level of the league system for rugby union in Germany, organised by the German Rugby Federation.
The league is predominantly amateur, with only one club in the league being officially a professional outfit, the Heidelberger RK.
From 2012 to 2015 the Bundesliga was expanded from ten to 24 and the league divided into four regional divisions of six teams each. Below the Bundesliga the 2. Bundesliga was organised in a similar fashion. From 2015 onwards the league returned to sixteen clubs.
