Sejm of the Duchy of Warsaw (Polish: Sejm Księstwa Warszawskiego) was the parliament of the Duchy of Warsaw. It was created in 1807 by Napoleon, who granted a new constitution to the recently created Duchy. It had limited competences, including having no legislative initiative. It met three times: for regular sessions in 1809 and 1811, and for an extraordinary session in 1812. In the history of Polish parliament, it succeeded the Sejm of the Polish-Lithuanian Commonwealth and was followed by the Sejm of the Congress Poland.
