The Nazi Gau (plural Gaue) system was originally established in a party conference on 22 May 1926,[2] in order to improve administration of the party structure. In the early stages, the borders and leaders of these Gaue fluctuated frequently, mainly due to internal power struggles.[3] The Gau Munich-Upper Bavaria was, for the most part, identical with today's Regierungsbezirk Upper Bavaria, of which Munich is the capital.
