Văitoianu took office as Romanian troops were engaged in an expedition to Hungary, where they were fighting against the newly proclaimed Hungarian Soviet Republic. The Supreme War Council of Allied Powers gave Romania an 8-day ultimatum to retreat its troops from Budapest to the provisional border settled by the Paris Peace Conference and to cease confiscation of Hungarian property, as well as to sign the peace with Austria and agree to guarantee minority rights throughout Greater Romania. Văitoianu's government refused to comply, and handed in its resignation on 30 November, leaving room for the bloc formed in Parliament by the Romanian National Party of Transylvania and the Peasants' Party of the Regat to form the Alexandru Vaida-Voevod cabinet, one which soon agreed to the Allies' demands.
