Passage: Prussia sent an army to support this independence movement, and ignored the Frankfurt National Assembly when Great Britain and Russia applied international pressure to end the war. The Prussians signed a peace at Malmö, requiring them to remove all Prussian troops from the two duchies and agree to all other Danish demands. The Treaty of Malmo was greeted with great consternation in Germany, and debated in the Assembly, but it was powerless to control Prussia. On September 16, 1848, the Frankfurt National Assembly approved of the Malmo Treaty by a majority vote. Public support for the National Assembly declined sharply following this vote, and the Radical Republicans publicly stated their opposition to the Assembly.After many diversions, the Frankfurt National Assembly took up the issue of a German constitution. In October 1848, King Frederick William IV of Prussia unilaterally issued a monarchist constitution. Under this new monarchist constitution, a Prussian Assembly was established. The Assembly was a bicameral legislature, consisting of a Herrenhaus (House of Lords) or upper house, whose members were selected by the provincial governments, and a Landtag (Country Diet), whose members were elected by male suffrage but were seated only through a complicated system of electoral committees. Otto von Bismarck was elected to this first Landtag. The Landtag was founded to undercut the authority of the Frankfurt National Assembly. In an attempt to regain some authority, in April 1849, the Frankfurt Assembly offered King Frederick William IV the crown as German emperor. He turned it down, saying he would accept a crown only by the grace of God, not "from the gutter".
