End of the January Uprising

Military Defeat. The armed struggle faced a crushing defeat on 21 February 1864, which presaged the end of the insurrection. Fighting continued intermittently during the winter of 1863–1864 on the southern edge of the Kingdom, near the Galician border. The uprising officially continued until the last insurgents were captured in 1864, though resistance persisted in some areas until 1865.

Political Repression. Tsar Alexander II curtailed support for the insurrection by abolishing serfdom in Poland in 1864, depriving the Polish gentry of their workforce. The fall of the uprising prompted severe political, social, and cultural reprisals, including deportations and pogroms of the Polish-Jewish population. Land taken from Polish peasants since 1864 was to be returned without compensation to punish the szlachta.

Diplomatic Shifts. In April 1864, Napoleon III abandoned the Polish cause, removing significant international support. Earlier, in June 1863, western powers had iterated conditions for a resolution, including amnesty and autonomous concessions. The decision to start conscription in mid-January 1863 had forced the uprising prematurely, setting the stage for the eventual defeat and diplomatic isolation.
