The reason for this is that Bavaria, Hamburg, Lower Saxony, and Bremen are the only places in Germany where the Oberliga, the State, and the Verband are geographically the same, while the other two states simply chose to call their leagues Landesligas when establishing them in 1990.
In Baden-Württemberg, Rhineland-Palatinate (southwestern part only), North Rhine-Westphalia (Westphalia), Mecklenburg-Western Pomerania, Brandenburg, Saxony-Anhalt, and Berlin, the Landesliga is the seventh tier, below the Verbandsliga.
In Bavaria, the Landesliga is divided into five divisions, South-West, South-East, Central, North-West, and North-East.
[2] In Brandenburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt, and Thuringia the league below the Landesligas is the Landesklasse (English: State Class).
[6] Of the 69 Landesligas in Germany 20 are set at tier six of the German football league system, these being:[2] Apart from the above-mentioned states, Landesligas also exist in the states of Baden-Württemberg, Rhineland-Palatinate (in the southwest part only), North Rhine-Westphalia (Westphalia), Mecklenburg-Western Pomerania, Brandenburg, Saxony-Anhalt, Berlin and as Landesklasse, in Saxony and Thuringia as tier seven leagues, below the Verbandsligas:[2] Uniquely, the Saarland has the Landesligas as the eighth tier of its league system; in Brandenburg, Mecklenburg-Western Pomerania, and Saxony-Anhalt the equivalent tier is Landesklasse.
