This study deals with the topic of anti-Czechoslovak activities in Bavaria in the 1920s, and looks at the activities of pan-German organisations and their crossborder activities focused on Czechoslovakia. It places the development of Bavaria’s irredentist activities in the context of the situation in Bavaria at the time, and also describes the impact of irredentist activities on Czechoslovak-German relations in the 1920s. In this regard, it manages to ascertain that the consequences of the above mentioned factors had an immediate impact on the cross-border activities of Pan-German organizations. In addition, individual activities are outlined and organizations involved in anti-Czechoslovak activities in Bavaria at the time are mapped. As such, the importance of this study is in its revealing of irredentism, previously little discussed, as one of the factors having a negative impact on Czechoslovak-German relations in the interwar period.
