The Battle of Kápolna was one of the decisive battles of the Hungarian war of Independence of 1848–1849, fought on 26 and 27 February 1849 between the Hungarian revolutionary army led by Lieutenant General Henryk Dembiński and the Austrian main army operating in Hungary Field Marshal Alfred I, Prince of Windisch-Grätz. After the Austrian offensive from the winter of 1848–1849, which resulted in losing the Western part of the country, the Hungarian army tried its first major counter-attack, but due to the disastrous leadership of the Polish Henryk Dembiński, the battle ended with an Austrian victory, and this did not influence only the military situation, but also the politics of central Europe: Franz Joseph I announced the March Constitution of Austria on 4 March 1849.
