Dominik Hieronim Radziwiłł

Dominik was born on 4 August 1786 in Biała Podlaska. He was the only son of Princess Sophie Friederike of Thurn and Taxis (1758–1800) and Prince Hieronim Wincenty Radziwiłł (1759–1786) of the Nesvizh line of the family. His father was Count of Kleck, the Great Cupbearer of Lithuania from 1779 and Governor of Minsk. After his father's death in September 1786, shortly after his birth, his mother remarried to Prince Andrzej Kazanowski and, after his death, to Count Mikołaj Ostroróg before her death in 1800.

His paternal grandparents were Prince Michał Kazimierz "Rybeńko" Radziwiłł and Anna Luiza Mycielska. His maternal grandparents were Karl Anselm, 4th Prince of Thurn and Taxis and Duchess Auguste of Württemberg (a daughter of Charles Alexander, Duke of Württemberg, who governed the Kingdom of Serbia as regent from 1720 until 1733).

Dominik was Ordynat of Nesvizh and Olyka and owner of Biržai, Dubingiai, Słuck and Kapyl estates. He fought in the Polish Legion on Napoleons' side and took part in Napoleon's invasion of Russia in 1812 and later died of wounds after the Battle of Hanau. Because of his involvement with Napoleon, Alexander I of Russia had confiscated his whole property. Only because of Prussia's intervention (since Dominik's cousin, Antoni Radziwiłł, was married to a Prussian princess) were the Radziwiłłs able to keep the family trust properties, while Mir Castle and 18,000 km² of land passed to Dominik's only legitimate child, Stephania, who had to marry a Russian subject, according to the Czar's order, whom she found in Ludwig zu Sayn-Wittgenstein-Berleburg. The castle then passed to her daughter Mary Sayn-Wittgenstein-Sayn, wife of German chancellor Chlodwig, Prince of Hohenlohe-Schillingsfürst, who was forced to sell it as a foreigner, according to newly introduced law, at the end of the 19th century.[1]

On 3 February 1807, he married Teresa Mniszech (1790–1852), a daughter of Count Michał Jerzy Mniszech and Urszula Zamoyska (niece of King Stanisław August Poniatowski). They divorced in 1809.

On 15 March 1809, he married Teofilia (née Morawska) Starzeński (1791–1828), the former wife of Józef Starzeński.[2] Together, they were the parents of:

• Aleksander Dominik Radziwiłł (1808–1859), who married Rosine Josephine Hietl.[3]
• Caroline Stefania Radziwiłł (1809–1832), who married Prince Ludwig zu Sayn-Wittgenstein-Berleburg, a son of German-Russian Field Marshal Peter Wittgenstein, on 14 June 1828 at St. Petersburg.[4]

Dominik died near Hanau on 11 November 1813. With the death of Dominik in 1813, the Nesvizh line lost its right to the ordynat as his only son, Aleksander Dominik, was born before his parents' marriage and was thus denied the title and inheritance of his forefathers. The ordynat of Nesvizh and Olyka fell into the hands of the younger Kletsk line, Dominik's cousin, Prince Antoni Radziwiłł.
