The Hungarian Revolution of 1848, also known in Hungary as Hungarian Revolution and War of Independence of 1848–1849 (Hungarian: 1848–49-es forradalom és szabadságharc) was one of a number of European Revolutions of 1848 and was closely linked to other revolutions of 1848 in the Habsburg areas. Although the Hungarian War of Independence failed, it is one of the most significant events in Hungary's modern history, forming the cornerstone of modern Hungarian national identity—the anniversary of the Revolution's outbreak, 15 March, is one of Hungary's three national holidays.
In April 1848, Hungary became the third country of Continental Europe (after France, in 1791, and Belgium, in 1831) to enact a law implementing democratic parliamentary elections. The new suffrage law (Act V of 1848) transformed the old feudal parliament (Estates General) into a democratic representative parliament. This law offered the widest right to vote in Europe at the time. The April laws utterly erased all privileges of the Hungarian nobility.
