The Hungarian Royal Honvéd army still had more than 1,400,000 soldiers when Mihály Károlyi was announced as prime minister of Hungary. Károlyi yielded to U.S. President Woodrow Wilson's demand for pacifism by ordering the unilateral self- disarmament of the Hungarian army. This happened under the direction of Béla Linder, (minister of war) on 2 November 1918. Due to the full disarmament of its army, Hungary was to remain without a national defence at a time of particular vulnerability. The Hungarian self-disarmament made the occupation of Hungary directly possible for the relatively small armies of Romania, the Franco-Serbian army and the armed forces of the newly established Czechoslovakia.
