Ostrogski family
Polish princely family
The House of Ostrogski (Polish: Ostrogscy; Lithuanian: Ostrogiškiai; Ukrainian: Острозькі, romanized: Ostroz'ki) was one of the more prominent families in the Kingdom of Poland, the Grand Duchy of Lithuania and in the Polish–Lithuanian Commonwealth. The family spanned from the 14th century Ruthenian noble Daniil Ostrogski to the 17th century Polish members. After the death of Janusz Ostrogski, the last male heir, most of the family's possessions passed to the Zasławski family.
The family played a crucial role in preserving the Eastern Orthodoxy, particularly during the Union of Brest signing in 1595. Members contributed to printing books in Church Slavonic (Kyiv [Ruthenian] recession) and supporting the Orthodox brotherhoods. By the 17th century almost all members turn to Catholicism and became fully associated with the Polish nation (Polonization). Many of their possessions were passed on or inherited by members of Sanguszko family.
History
The Ostrogski family was most likely of Rurikid stock and descended from Sviatopolk II of Kiev. Some scholars however claim that their descent is from the Galicia-Volhynia line of the Rurikid dynasty. Vasilko Romanovich (c.1256-1282), Prince of Slonim, may have been the grandfather of Prince Danylo Ostrozky.
