Question: What is one of five leagues at this level, together with the Regionalliga Bayern, Regionalliga Nordost, Regionalliga Südwest and the Regionalliga West, that was apart of the four regional sections of the first year of the Regionalliga?
Context: The 1966–67 Regionalliga was the fourth season of the Regionalliga, the second tier of the German football league system.  The league operated in five regional divisions, Berlin, North, South, Southwest and West.  The five league champions and all five runners-up, at the end of the season, entered a promotion play-off to determine the two clubs to move up to the Bundesliga for the next season.  The two promotion spots went to the Regionalliga Berlin and Regionalliga Südwest champions Alemannia Aachen and Borussia Neunkirchen. The 2013–14 Regionalliga was the sixth season of the Regionalliga, the second under the new format, as the fourth tier of the German football league system.  The champions of Regionalliga Nord – Holstein Kiel – and Regionalliga Nordost – RB Leipzig – as well as Regionalliga Südwest runners-up SV Elversberg were promoted to the 3.  Liga.  Alemannia Aachen, Babelsberg 03 and Kickers Offenbach were relegated from 3.  Liga. The 1994–95 Regionalliga season was the first year of the Regionalliga as the third tier of German football.  There were four regional sections, Nord, Nordost, West-Südwest and Süd, each with eighteen teams.  Most teams qualified from the Oberliga, which dropped to become a fourth-tier league, while five teams were relegated from the previous year's 2.  Bundesliga.  In the Nord section, four teams were promoted from the formerly fourth-tier Verbandsliga. The Regionalliga Nord (English: Regional League North ) is the fourth tier of the German football league system in the states of Lower Saxony, Schleswig-Holstein, Bremen and Hamburg.  It is one of five leagues at this level, together with the Regionalliga Bayern, Regionalliga Nordost, Regionalliga Südwest and the Regionalliga West.  Until the introduction of the 3.  Liga in 2008 it was the third tier. The Regionalliga Südwest (English: Regional League Southwest ) is the fourth tier of the German football league system in the states of Hesse, Baden-Württemberg, Rhineland-Palatinate and Saarland.  It is one of five leagues at this level, together with the Regionalliga Bayern, Regionalliga Nordost, Regionalliga Nord and the Regionalliga West. The 2012–13 Regionalliga was the fifth season of the Regionalliga as the fourth tier of the German football league system.  From this season onwards, the structure of this tier has changed.  The three division format administrated by the German FA has been replaced by five leagues, each of which is administrated by its respective regional FA.  Additionally, the leagues will be structured on geographical affiliation, in contrast to the partially arbitrary divisional alignment.  League champions will qualify for a promotion play-off.  Additionally, the Regionalliga Südwest runners-up will qualify. The 2014–15 Regionalliga was the seventh season of the Regionalliga, the third under the new format, as the fourth tier of the German football league system.  The champions of Regionalliga West – Fortuna Köln – and the winner – SG Sonnenhof Großaspach – and third-placed team - FSV Mainz 05 II - of the Regionalliga Südwest were promoted to the 3.  Liga.  SV Elversberg, Wacker Burghausen and Saarbrücken were relegated from 3.  Liga. The Regionalliga West is a German semi-professional football division administered by the Western German Football Association based in Duisburg.  It is one of the five German regional football associations.  Being the single flight of the Western German state association, the Regionalliga is currently a level 4 division of the German football league system.

For 2013-14, there were five regions of the league, the Regionalliga West, Regionalliga Nord, Regionalliga Ost, Regionalliga Südwest, and the Bayernliga.
