The Collegium Nobilium was a Jesuit foundation in Warsaw between 1752 and 1777. It was intended to provide an élite education for the sons of Magnates of Poland and Lithuania, and other leading Szlachta families, likely to run the country or represent it abroad. It is sometimes confused with another longer established educational institution with the same name, run by the Piarists order in the capital.

Feliks Walezjusz Władysław Łubieński was a Polish politician, jurist, Minister of Justice in the Grand Duchy of Warsaw, starosta of Nakieł, a member of the Friends of the Constitution and a Prussian count. With the Code Napoleon, he introduced civil marriage and divorce in traditionally Catholic Poland.
