January Uprising The January Uprising (Polish: "powstanie styczniowe", Lithuanian: "1863 m. sukilimas", Belarusian: "Паўстанне 1863-1864 гадоў") was an uprising in the former Polish-Lithuanian Commonwealth (present-day Poland, Lithuania, Belarus, Latvia, parts of Ukraine, and western Russia) against the Russian Empire. It began on 22 January 1863 and lasted until the last insurgents were captured in 1864.

They took place on May 7–9, 1863, in the area of Lithuanian town of Biržai, which at that time belonged to the Russian Empire.
