Th is article analyzes the transition of German summer solstice celebrations in the Bohemian Lands from folk festivals to radical right-wing mobilizing rituals between the turn of the twentieth century and 1938. During the interwar period, these celebrations were a response to the historic and/ or invented traditions of the First Republic, which were at the intersection of Czech (-oslovak) national identity as a construction of linguistic-cultural affi liation. Th e transformation of the Sonnwendfeier to a modern, mass, radical right-wing tool for organizing and maintaining a racial community parallels the growing radicalization of the nationally identifying Germans across Habsburg Central Europe between the world wars. Summer solstice celebrations played an important role in the construction of a Sudeten German community from the bottom up during the 1930s.
