[2] Members of the group and their publications had played major roles in preparing for and organizing the meeting of the parliament,[6] for example in publicity in the Deutsche Zeitung, a liberal newspaper that came to be the organ of the faction,[7][8] and participation in the Heppenheim Meeting, the Heidelberg Assembly, and the Vorparlament, the preliminary assembly that met in the Paulskirche from 31 March to 3 April 1848.
The majority of the Casino members joined with the Westendhall faction to form the coalition of Erbkaiserliche (hereditary imperialists) that met in the concert hall of the Gasthof zum Weidenbusch and pushed through the specification of constitutional monarchy as the preferred political form of the sought-after national state.
In September 1848, the Landsberg faction split off from Casino;[13] its members advocated a more prominent role for the national assembly.
[14] Following the resignation of the Austrian deputy Anton von Schmerling on 21 December 1848, the Casino members who preferred a "Greater Germany" including Austria likewise split off under the leadership of Karl Jürgens and formed the more conservative Pariser Hof.
[15][16][17] Jacob Grimm was nominally a member of the Casino faction, but after the 5 September 1848 vote, spearheaded by Dahlmann, rescinding the Malmö ceasefire between Prussia and Denmark, he took leave of absence and then resigned as a deputy.
