In the course of the November Revolution of 1918, the New Exchange was briefly in the political spotlight when the politician Alfred Henke announced the seizure of power by a Worker's council and the dissolution of the Bremen Senate and Bürgerschaft in a hall of the building, marking the beginning of the short-lived Bremen Civic Republic. In 1934 the New Exchange was closed and the civic trade in securities was transferred to the Hanseatic Exchange in Hamburg.
