# Czetwertyński family

The House of Czetwertyński or Chetvertynsky (also Czetwertyński-Światopełk and Sviatopolk-Chetvertynsky) is a Polish princely family of Ruthenian origin that was founded under the Crown of the Kingdom of Poland in modern-day Volhynia Ukraine. The family takes its name from the village of Chetvertnia, Lutsk county, in modern-day Manevychi Raion, Volyn Oblast.

## History

According to the family's legend, the progenitor of the family is the Grand Prince of Kyiv, Sviatopolk II. The first documented member of the family is Oleksander Chetvertynsky, who is mentioned in 1388. The family was accepted into the princely houses of Poland and Lithuania in 1569 and their Russian title of prince was confirmed in 1843.
In 1492, Prince Fedir Mykhailovych Chetvertynsky was the Lithuanian-Ruthenian ambassador to Wallachia. Over time, the family were Polonized and Catholicized, but some members remained adherent to the Eastern Orthodox religion.
Prince Stepan Sviatopolk-Chetvertynsky (1575–1659) played a key role in re-establishing the Ukrainian Orthodox Church of the Ecumenical Patriarchate of Constantinople in 1620. His son Mykola Sviatopolk-Chetvertynsky (?–1659) was a relative of the Hetman of Zaporizhian Host, Ivan Vyhovsky.
Two of the most notable representatives of the family were Hedeon Zakharovych Svyatopolk-Chetvertynsky, the Metropolitan of Kyiv, Galicia and all Little Russia in 1685–90, and Antoni Stanislaw's daughter Marie, who was Alexander I of Russia's mistress and had children by him. A nephew of Hedeon, Yurii Sviatopolk-Chetvertynsky (?-c. 1717–22), was a son-in-law of the Hetman of Zaporizhian Host, Ivan Samoylovych.
After Antoni Stanisław Czetwertyński-Światopełk was lynched in 1794 by Polish nationals in Warsaw during the Kościuszko Uprising, his family resettled in Saint Petersburg, in the Russian Empire. It received major land grants from Catherine the Great, such as the manor of Filimonki near Moscow.
