This article explores the making of a unified Muslim community in interwar Austria and its ultimate failure. It argues that while the Islamischer Kulturbund Wien represented a visionary idea which aimed at establishing a Muslim community, rooted in both faith and Austrian society, it ultimately remained the dream of only a select few individuals. The association succeeded in strategically positioning itself as the representative body of Muslims in Austria; however, due to a lack of commitment from its members and the rise of fascism in Austria, this early attempt to establish a unified Muslim community in Austria eventually failed. By incorporating unofficial sources in various languages, including private letters, oral history interviews, and newspapers, alongside official archival material, the article amplifies the voice, perspective and agency of key Muslim figures involved, allowing for a more fully developed understanding of the internal and external dynamics of Muslim activism in interwar Vienna.
