House of Sanguszko

Sanguszko (Belarusian: Сангушка, Ukrainian: Сангушко) is a Polish noble and aristocratic family of the Ruthenian stock from the Gediminid dynasty. Like other princely houses of Polish–Lithuanian Commonwealth, its origin are considered murky. Present historical opinion holds in favour of their descent from Algirdas' grandson Alexander Feodorovich (fl. 1433–1443), lord of Kovel and Liuboml, whose name can be shortened to Sangush. The family supposedly descends from two lines, associated with two of his sons, Alexander and Michael.

The senior line, called the Sanguszko-Koszyrski, has been extinct since the death of Adam Aleksander Sanguszko in 1653. The junior line, or the Sanguszko-Kowelski, of Szymon Samuel Sanguszko, subsequently assumed the title Sanguszko-Lubartowicz, according to the erroneous assumption of their descent from Algirdas' younger brother Lubart.

Prince Paweł Karol Sanguszko-Lubartowicz (1682–1752), a Court and Grand Marshal of Lithuania, greatly expanded his holdings through his second marriage with Marianna Lubomirska, heiress of Ostroh. His chief residence at Slavuta (now in Ukraine) was embellished with a famous collection of Persian carpets, known as Sanguszko carpets. Hieronymous Sanguszko (1743–1812) founded the Slavuta stud, establishing the family as breeders of Arabian horses.
