The political beliefs of the "Hôtel Lambert" faction were derived from the 3 May Constitution, which its members had supported. The Hôtel Lambert played an important role in keeping the "Polish question" alive in European politics, by continually keeping the Polish cause on the agenda. It also served as a safe harbour for Polish emigés and royalists, exiled from their country after the unsuccessful uprising against Russia. Among other notable politicians who took part in the Hôtel Lambert's activities were Władysław Czartoryski, son of Adam, Józef Bem, Henryk Dembiński, Karol Kniaziewicz, Julian Ursyn Niemcewicz, Władysław Stanisław Zamoyski, Władysław Ostrowski and Leon Kaplinski.
