Diplomat As a successful diplomat between 1802 and 1819, Humboldt was plenipotentiary Prussian minister at Rome from 1802, ambassador at Vienna from 1812 during the closing struggles of the Napoleonic Wars, at the congress of Prague (1813) where he was instrumental in drawing Austria to ally with Prussia and Russia against Napoleon; a signer of the peace treaty at Paris and the treaty between Prussia and defeated Saxony (1815), and at the congress at Aachen in 1818. However, the increasingly reactionary policy of the Prussian government made him give up political life in 1819; and from that time forward he devoted himself solely to literature and study.Gordon Craig, "Wilhelm von Humboldt as a diplomat", in Craig, Studies in International History (1967).
