The January Uprising was an insurrection principally in Russia's Kingdom of Poland that was aimed at putting an end to Russian occupation of part of Poland and regaining independence. It began on 22 January 1863 and continued until the last insurgents were captured by the Russian forces in 1864.
It was the longest-lasting insurgency in partitioned Poland. The conflict engaged all levels of society and arguably had profound repercussions on contemporary international relations and ultimately transformed Polish society.
