The Centralmärzverein faction dominated the Rump Parliament during the last period of the revolution, and after the various uprisings of 1849 were suppressed, its many clubs were banned throughout Germany. The Centralmärzverein was founded on 21 November 1848 with a stated goal to protect the 'March achievements.' It was formed out of the Donnersberg faction together with Deutscher Hof and Westendhall members (see below).
The Left was at the time also called the 'Wholes', and consisted of a coalition of extreme and moderate republicans. The largest factions were Casino, Württemberger Hof and the United left which was also known as the Märzverein (March association). They coalesced as groups of like-minded representatives started meeting, and were named after the various hostelries at which they met. The factions in the Frankfurt Assembly were groups ( German: Fraktionen) that developed among delegates to the Frankfurt Parliament that met from to in the Paulskirche in Frankfurt am Main.
