# Wilhelm Radziwiłł

Prince Fryderyk Wilhelm Paweł Mikolaj Radziwiłł (19 March 1797 – 5 August 1870) was a Polish nobleman who was the founding president of the Berlin Numismatic Society.

## Early life

Radziwiłł was born on 19 March 1797 in Berlin. He was the eldest son of Prince Antoni Henryk Radziwiłł, the Duke-Governor (Polish: książę-namiestnik, German: Statthalter) of the Grand Duchy of Poznań, an autonomous province of the Kingdom of Prussia, and Princess Louise of Prussia (1770–1836). Among his surviving siblings were Prince Ferdynand Fryderyk Radziwiłł (who died unmarried); Princess Eliza Fryderyka Radziwiłł (the desired bride of Prince William of Prussia, who later became William I, German Emperor, but they were not allowed to marry); Prince Bogusław Fryderyk Radziwiłł (who married Countess Leontyna von Clary und Aldringen); Prince Władysław Radziwiłł (who died unmarried); and Princess Wanda Augusta Wilhelmina Radziwiłł (who married their first cousin, Prince Adam Czartoryski).
His paternal grandparents were Prince Michał Hieronim Radziwiłł and Helena Przeździecka. His aunt, Princess Angelika Radziwiłł, was the wife of Prince Konstanty Adam Czartoryski. Through his brother, Prince Bogusław, he was uncle to Prince Ferdynand Radziwiłł. His maternal grandparents were Margravine Elisabeth Louise of Brandenburg-Schwedt and Prince Augustus Ferdinand of Prussia (a younger brother of the Prussian King Frederick the Great). Through his mother, he was the great-grandson of King Frederick William I of Prussia, great-great-grandson of King George I of Great Britain, cousin of William I, German Emperor and Czar Alexander II of Russia.
Wilhelm studied at the Friedrich Wilhelm Gymnasium and the Friedrichswerder Gymnasium in Berlin.

## Career

In 1813, he enlisted as a Second lieutenant in the 3rd Army Corps under the command of Friedrich Wilhelm Freiherr von Bülow. He took part in the Battles of Leipzig and Laon, the Battles of Bois-le-Duc, Deuren, Leonhout, the Siege of Soissons and the Capture of Arnhem. He was awarded the Iron Cross, 2nd Class, and the Order of the Sword; he was promoted to captain in May 1815 and in turn assigned to the Bülow corps.
After the 1815 Treaty of Paris, he entered the Prussian Staff College with the rank of Major to improve his skills and at the same time became a member of the Military Society of Berlin. In 1821, he received his transfer as battalion commander to Posen.
In 1829, he toured the Italian peninsula and visited Greece and Constantinople to gain an insight into the military and political situation in the crisis areas of the time. Upon his return, he was given command of the 11th Grenadier Regiment in Breslau and was promoted to Colonel in 1832.
The death of his father forced him to relinquish command and devote himself to managing his estates, becoming a member of the Prussian House of Lords. In 1833, he became a Knight of Honor of the Sovereign Order of Malta. As commander of the 6th Landwehr Brigade, he returned to active service in 1838. In 1839, he was promoted to Major general and in 1846, to Lieutenant general.
During the First Schleswig War, he took command of the Prussian troops under Field Marshal Friedrich Graf von Wrangel against Denmark. For his conduct at Schleswig and Düppel, he received the Order Pour le Mérite.
In May 1849, he was appointed Commandant of Torgau and, in 1852, Commanding general of the 4th Army Corps in Magdeburg. In recognition of his achievements, he was appointed commander of the 27th Infantry Regiment. With the rank of General of the Infantry, he commanded the 3rd Army Corps from 1858 and held the post of military governor of the Province of Brandenburg during the mobilization of 1859.
With the reorganization of the army from 1860, he was head of the Corps of Engineers and pioneers and general inspector of Prussian fortresses.
In 1843, he was one of the founders of the the Numismatische Gesellschaft zu Berlin [de] (Berlin Numismatic Society), the oldest numismatic association in Germany. It was an initiative of the Berlin lecturer Bernhard von Koehne, later director of the Hermitage in St. Petersburg. Radzwill served as president of the new society for several decades until his death in 1870. Chamberlain Adolf von Rauch succeeded him as president of the Society.
