Prince Antoni Henryk Radziwiłł was a Polish and Prussian noble, aristocrat, musician, and politician. Initially a hereditary Duke of Nieśwież and Ołyka, as a scion of the Radziwiłł family he also held the honorific title of a Reichsfürst of the Holy Roman Empire. Between 1815 and 1831 he acted as Duke-Governor of the Grand Duchy of Posen, an autonomous province of the Kingdom of Prussia created out of Greater Polish lands annexed in the Partitions of Poland.
