Abstract This article examines the role of associations as protest and riot brokers during the Badeni crisis of 1897 in Habsburg Austria. Drawing on concepts from political science, it demonstrates how these collective actors acted as crucial intermediaries between political leaders and local communities. Through meetings and rallies, associations facilitated the translation of parliamentary conflicts into street politics, while at the same time enabling demonstrations to escalate into violent riots. The article shows how civil society organizations deployed narratives to legitimize street politics and provided emotional framing and organizational capacity that individual activists often lacked. In doing so, associations expanded political participation in Habsburg Austria by bringing broader strata of society into the political arena, while simultaneously destabilizing it by fostering exclusionary violence. By conceptualizing associations as both protest and riot brokers, the article reinterprets the Badeni crisis not simply as evidence of national hatred but as a manifestation of mass political mobilization in a rapidly modernizing society.
