Overview
The league was formed in 1927, from the clubs of the Bezirksliga Rhein and the southern half of the Bezirksliga Rheinhessen-Saar. The clubs from the Bezirksliga Rheinhessen-Saar which did not become part of the new league were added to the new Bezirksliga Main-Hessen instead. While the majority of clubs originated from the Palatinate and the Saarland it also incooperated some clubs from the state of Baden, from the Mannheim area and from the Prussian Rhine Province, from Trier.
The league operated from the start in two regional divisions, the Rhein-division, named after the river Rhein and the Saar-division, named after the river of Saar. The first played with eleven, the second with ten clubs in its first season 1927-28. The clubs in each division played each other in a home-and-away round with the division winners advancing to the Southern German championship, which in turn was a qualification tournament for the German championship. A Bezirksliga final was not played.
The second and third placed team in each division qualified for another round, the Bezirksliga runners-up round, to determined one more team which would gain entry to the German finals.
The leagues were reduced to nine teams each in the following season but remained unchanged in modus otherwise. For the 1929-30 season, both divisions then operated on a strength of eight teams, a system that also applied in the following season.
In the 1931-32 season, both divisions expanded in strength to ten teams. The Southern German finals were also reorganised with the top two teams from each division advancing to the Northwest finals group.
In its last season, 1932–33, both divisions operated on a strength of ten clubs.
With the rise of the Nazis to power, the Gauligas were introduced as the highest football leagues in Germany. In the region, the Gauliga Südwest/Mainhessen replaced the Bezirksliga Rhein-Saar as the highest level of play. The clubs from Mannheim however entered the new Gauliga Baden while the teams from Trier went to the Gauliga Mittelrhein.
