The rule of Nicholas also meant the end of political traditions in Poland; democratic institutions were removed, an appointed—rather than elected—centralized administration was put in place, and efforts were made to change the relations between the state and the individual. All of this led to discontent and resistance among the Polish population. In January 1831, the Sejm deposed Nicholas I as King of Poland in response to his repeated curtailing of its constitutional rights. Nicholas reacted by sending Russian troops into Poland, resulting in the November Uprising.
