After the German occupation, a
Gauliga Sudetenland championship was organized by the
Nazi Sports Office in 1938–39 in the form of a knock-out competition involving the four regional champions, the
Bezirksmeister. The winner of this competition qualified for the
German championship. Throughout the league's existence, only ethnically German clubs were permitted to take part in the
Gauliga. Except for the 1938-39 edition, when clubs still operated under their original names, almost all teams had to adopt the prefix
NTSG standing for
Nationalsozialistische Turnergemeinde and were under direct Nazi control. The only clubs outside this system were the military clubs. In March 1939, Nazi Germany went to occupy the remaining part of Czechoslovakia. It formed the German controlled
Protectorate of Bohemia and Moravia and the nominally independent country of
Slovakia. Ethnically German clubs from the newly occupied region took part in the
Gauliga Sudetenland, especially from
Prague. The league proper started in 1939, with eleven teams in two groups. The two group champions played a one-off final to determine the
Sudetenland champion. The season after the league was reduced to seven teams in an otherwise unchanged setup. The season was greatly shortened due to a number of clubs dropping out throughout it. The 1941–42 season saw a return to a more organised league system with eighteen clubs in three equal divisions. The three divisional champions then played a home-and-away finals round to determine the
Sudetenland champion. The following season, the league was again reduced in numbers throughout the season, finishing with fifteen clubs in the same three groups, four in the eastern group, five in the central and six in the western group. Again, a finals tournament for the group champions was played. From 1943, clubs from the
Protectorate left to take part in the new
Gauliga Böhmen und Mähren. In its last completed season, the league operated with thirteen clubs in two divisions, with a home-and-away final of the two divisional champions at the end. Not every club however completed their full program of matches. The imminent collapse of
Nazi Germany in 1945 affected all
Gauligas and its doubtful whether the 1944–45 season in the
Gauliga Sudetenland got under way at all. ==Members of the league==
