For the first time since the Napoleonic wars Poland tried to regain its independence. A revolt in Warsaw by young officers led by Piotr Wysocki sparked a revolution which spread to almost all the pre partitions Polish-Lithuanian territories controlled by Russia.
This revolution is also called the November uprising because the revolt started on the night of the 29 November 1830.
