Polish nobleman and politician who was the Polish envoy to London from 1919 to 1920, the Polish Foreign Minister from 1920 to 1921, and a member of the Polish Senate from 1935 to 1939.
He was the son of Prince Ferdynand Radziwiłł (1834–1926) and Princess Pelagia Sapieżanka. His siblings were Michał Radziwiłł Rudy, Karol Ferdynand Radziwiłł, Małgorzata.
After the Soviet invasion of Poland in 1939, he was arrested by NKVD. Imprisoned in the infamous Lubyanka prison, he was personally interrogated by Lavrentiy Beria. He was released after a few months after international pressure from, among others, the Italian royal family (due to the prestige of the Radziwiłł family). He was briefly imprisoned by the Germans during the Warsaw Uprising in 1944.
After the war in 1945 he was again arrested by NKVD; his wife would die in a communist prison in 1947. He was eventually released, with most of his possessions confiscated and nationalized by the communist government.
Radziwiłł died in his two-room apartment in Warsaw, Poland on 4 October 1967, aged 87. Before the War, he owned two palaces in Warsaw.
