In 1830, he was appointed
Landrat official in the
Uckermark district. In 1833, he became Vice-president of the Pomeranian
Stralsund government region. One year later, he assumed the position of President in the
Aix-la-Chapelle (Aachen) region, from 1838 in
Merseburg,
Saxony. In 1840 he became governor (
Oberpräsident) of the
Grand Duchy of Posen. In 1842 Arnim was called back to Berlin to be appointed Prussian
State Minister of the Interior. Nevertheless, he resigned in 1845 because his plans for a constitution for Prussia were at odds with King
Frederick William IV's romantic ideals. When the March Revolution broke out in 1848, his services were again in demand. From 19 March 1848, he acted as the first Prussian Minister-President and
Foreign Minister. However, he again resigned within a few days after the king chose to place himself at the head of the national movement. A member of the
Provincial Brandenburg
Landtag assembly since 1839, Arnim from 18 May to 10 June 1848 was a representative for
Prenzlau in the
Frankfurt Parliament and also was a member of the short-lived
Erfurt Union Parliament in 1850. He belonged to the newly established
Prussian House of Representatives from 1849 and later joined the
House of Lords chamber of the
Prussian Parliament. Arnim is known to this day for his remarks as Prussian Interior Minister during the
Vormärz era concerning
Heinrich Heine's poem
The Silesian Weavers. The verses were published in the
Vorwärts! weekly newspaper after an 1844 riot in the
Province of Silesia, which later also inspired the drama
The Weavers by
Gerhart Hauptmann. In a report to King Frederick William IV he described Heine's poetry as "an address to the poor amongst the populace, held in an inflammatory tone and filled with criminal utterances" ("
eine in aufrührerischem Ton gehaltene und mit verbrecherischen Äußerungen angefüllte Ansprache an die Armen im Volke"). Subsequently, the Royal Prussian Kammergericht banned the poem, which in 1846 led to a prison sentence for a person who had dared to publicly recite it. ==Personal life==
