In May 1848 he resigned, but was made Foreign Minister of Prussia in early September 1848 in the government of Ernst von Pfuel, a position he only held for a short time however. Then in February 1849 he was elected by the second electoral district of Gumbinnen to the first chamber of the Prussian Parliament, which sent him in 1850 to Erfurt, into the "Staatenhaus" (the chamber of the Erfurt Union parliament that represented the individual states). He was once again elected a member of the Prussian first chamber in the summer of 1850, and joined the moderate right-wing "Partei Jordan". In 1851 he became a member of the "Landtag" of the Province of Prussia, and participated in its session from 1851 to 1852 in Berlin. When the Prussian first chamber became the Prussian House of Lords, the King made him a hereditary member. In 1861 he became the grand-master of the wardrobe at court. He died in April 1874.
