The Regionalliga West/Südwest was formed in 1994 to form a regional third level of play between the 2. Bundesliga and the Oberligas Westfalen, Nordrhein and Südwest. The league was made up of 18 clubs, with six each from the three regions it covered. It was formed alongside three other Regionalligas, the Regionalliga Nord, Nordost and Süd.
The founding members were:
From the 2. Bundesliga:
- Rot-Weiß Essen (Oberliga Nordrhein region)
From the Oberliga Westfalen:
- Arminia Bielefeld
- SC Verl
- TuS Paderborn-Neuhaus
- SpVgg Erkenschwick
- SG Wattenscheid 09 II
- Preußen Münster
From the Oberliga Nordrhein:
From the Oberliga Südwest:
The league varied the number of clubs it contained, 18 in the first season 1995, 19 the next year, 18 again in 1997 and 1998, 17 in 1999 and 20 in its last season.
The league winner was always promoted to the 2. Bundesliga and in two seasons the runners-up also was. The regulation on which of the runners-up of the four Regionalligas went up meant that promotion was allocated in an alternating way. After 1995, it gave the runners-up a chance to gain promotion too via a play-off.
The league only existed for six seasons. In 2000, the numbers of Regionalligas was reduced from four to two which meant that most clubs from Nordrhein-Westfalen, with the exception of the Sportfreunde Siegen, went to the Regionalliga Nord. The clubs from Rheinland-Pfalz and Saarland went to the Regionalliga Süd.
In 2008, the number of Regionalligas will be expanded from two to three and there will be a new Regionalliga West which will cover exactly the area the old Regionalliga West/Südwest did, but will then be the fourth tier of German football.
Disbanding of the Regionalliga West/Südwest
When the league was disconntinued in 2000, the first two clubs in the league went to the 2. Bundesliga, clubs placed third to twelfth moved to the two remaining Regionalligas, seven to the north and three to the south. The other eight league teams were relegated down to the Oberligas.
To the Regionalliga Nord:
- SG Wattenscheid 09
- Fortuna Düsseldorf
- Rot-Weiß Essen
- SC Preußen Münster
- SC Verl
- Borussia Dortmund II
- KFC Uerdingen 05
To the Regionalliga Süd:
The Sportfreunde Siegen were the oddity in this distribution, being from the state of Nordrhein-Westfalen which had all its clubs in the northern group except the Sportfreunde. The reason for this was the fact that Siegen is in the far south of the state.
