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 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. 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.The crucial turning point came when the new Austrian monarch Franz Joseph I arbitrarily revoked the April laws without any legal right (since they had already been ratified by King Ferdinand I). This unconstitutional act irreversibly escalated the conflict between him and the Hungarian parliament. The new constrained Stadion Constitution of Austria, the revocation of the April laws, and the Austrian military campaign against the Kingdom of Hungary resulted in the fall of the pacifist Batthyány government (who sought agreement with the court) and led to Lajos Kossuth's followers (who demanded full independence for Hungary) suddenly gaining power in the parliament. Austrian military intervention in the Kingdom of Hungary resulted in strong anti-Habsburg sentiment among Hungarians, and the events in Hungary grew into a war for total independence from the Habsburg dynasty. Around 40% of the private soldiers in the Hungarian Revolutionary Volunteer Army consisted of ethnic minorities of the country. Regarding the officer staff of Hungary: Around half of the officers and generals of the Hungarian Honvéd Army had foreign origin. There were at least as many ethnic Hungarian professional officers in the Imperial Habsburg army as in the Hungarian revolutionary Honvéd army.In regard to diplomacy and foreign policy during the revolution, the Hungarian liberals - similar to the other European liberal revolutionaries of 1848 - were primarily motivated by ideological considerations. They supported countries and forces that aligned with their new moral and political standards. They also believed that governments and political movements sharing the same modern liberal values should form an alliance against the "feudal type" of monarchies. This outlook was similar to modern liberal internationalism.After a series of serious Austrian defeats in 1849, the Austrian Empire came close to the brink of collapse. The new emperor Franz Joseph I had to call for Russian help in the name of the Holy Alliance. In the hope of Russian military support, the young Emperor Franz Joseph kissed the hands of the Ruler of all the Russians in Warsaw on 21 May 1849. Nicholas I of Russia agreed with Franz Joseph and sent a 200,000 strong army with 80,000 auxiliary forces. The joint Russo-Austrian army finally defeated the Hungarian forces, Habsburg power was restored and Hungary was placed under martial law. Source: Wikipedia (en)
