Overview
The Familia ("The Family", from Latin familia) was the name of an 18th-century Polish political faction led by the House of Czartoryski and allied families. It was formed towards the end of the reign of King of Poland Augustus II the Strong (reign. 1697–1706, 1709–1733). The Familia's principal leaders were Michał Fryderyk Czartoryski, Grand Chancellor of Lithuania, his brother August Aleksander Czartoryski, Voivode of Ruthenia (Rus), their sister Konstancja Czartoryska, and their brother-in-law (from 1720), Stanisław Poniatowski, Castellan of Kraków.
Formation
During the interregnum in 1733, the Familia supported Stanisław I Leszczyński for King. Polish Kings in the period were elected by ballot, by the nobility (Elective Monarchy). The Familia decided to support the Saxon Frederick Augustus II as candidate (elected King Augustus III - reign. 1734–1763 in Poland), instead, and thus became a party of the Royal Court. Following the failure of the Polish Sejm to pass reforms (between 1744 and 1750) the Familia distanced itself from the struggling Royal Court. In foreign affairs, they now represented a pro-Russian orientation (see "War of Polish Succession").
During the next Polish interregnum (1763–1764) near the end of the "Seven Years' War" in Europe, an armed Russian intervention in Poland gave the Familia the opportunity to vanquish their opponents at home. When in 1764 Adam Kazimierz Czartoryski declined to seek election to the throne, the Czartoryskis agreed to the election, instead, of their kinsman Stanisław August Poniatowski, a one-time lover of the Russian Empress Catherine II "the Great".
