Hungarian Defence Forces
In April 1867, the Austro-Hungarian Empire was established. Franz Josef, the head of the ancient Habsburg dynasty, was recognized as both Emperor of Austria and King of Hungary. Nevertheless, the issue of what form the Hungarian military would take remained a matter of serious contention between Hungarian patriots and Austrian leaders. As the impasse threatened the political union, Emperor Franz Josef ordered a council of generals in November of the same year. Ultimately, the leaders resolved on the following solution: in addition to the joint (k.u.k.) army, Hungary would have its own defence force, whose members would swear their oath to the King of Hungary (who was also Emperor of Austria) and the national constitution, use the Hungarian language of command, and display their own flags and insignia. (Austria would also form its own parallel national defence force, the "Landwehr".) As a result of these negotiations, on 5 December 1868, the Royal Hungarian Landwehr ("Magyar Kiralyi Honvédség", or Defence Force) was established.
Hungarian–Romanian War
In 1918 the Austro-Hungarian Monarchy politically collapsed and disintegrated as a result of a defeat in the Italian Front (World War I). During the war Count Mihály Károlyi led a small but very active pacifist anti-war maverick fraction in the Hungarian parliament. He even organized covert contacts with British and French diplomats in Switzerland during the war. On 31 October 1918 the Aster Revolution in Budapest brought Hungarian liberal aristocrat Mihály Károlyi, a supporter of the Entente (Allied nations), to power. The huge Hungarian Royal Honvéd army still had more than 1.400.000 soldiers when Mihály Károlyi was announced as prime minister of Hungary. After World War I Károlyi yielded to Woodrow Wilson's (US) demand for pacifism by ordering the disarmament of the Hungarian army. This happened under the direction of Béla Linder, minister of war in the Károlyi government. Due to the full disarmament of its army, Hungary remained without a national defence at a time of particular vulnerability.
