The Gau Bayerische Ostmark was formed in 1933, when Hans Schemm united the three Gaue of Oberpfalz, Niederbayern and Oberfranken into one in an internal power struggle. The term Bayerische Ostmark was coined after the First World War for the region to refer to the fact that the area now bordered the new Czechoslovakia, a country perceived as hostile to Germany.
