The Hungarian Revolution of 1848, also known in Hungary as Hungarian Revolution and War of Independence of 1848–1849 was one of many European Revolutions of 1848 and was closely linked to other revolutions of 1848 in the Habsburg areas. Although the revolution 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.
