The small counterrevolutionary National Army under Miklós Horthy entered Budapest two days after the withdrawal of the Romanian Army on 14 November 1919, which evacuated the city after looting. Thanks to the mediation of the envoy of the Entente, a coalition government was formed on 23 November with Huszár as its head, despite no political experience in this area, although he had once been a teacher. The previous president of the government, István Friedrich, was relieved by his ambition, which collided with that of Horthy, and he inspired little confidence in Horthy because of his previous closeness to Mihály Károlyi. The new government included the Party of Smallholders, National-Democrats and Social-Democrats, among others, and was intended to be a transitional cabinet until the future elections to be held by extended suffrage and secret ballot. Friedrich remained in the Council of Ministers and was responsible for defence, a position unimportant since the army obeyed Horthy. His party, the KNEP, however, was the one that maintained the largest number of portfolios and the most important ones. Friedrich and the other KNEP supporters were to dominate power by controlling the cabinet, as would have happened if Horthy had kept his promise to surrender control from the armed forces to the government. The executive had little control over the bands which travelled across the country spreading the White Terror, whose victims included Jews. In December Huszár enacted a decree allowing the arrest of any person representing a "danger to public order" which led to the arrest without charge of thousands of people, including the most prominent Social-Democrats still in the country.
In the face of persecution and a lack of support in the countryside, the Social Democrats decided not to stand for election, which the progressive parties still won. The Social Democrats had remained in government only because of the country's grave situation and with the aim of moderating counterrevolutionary tendencies, but on 18 December 1919, they had been about to withdraw their ministers from the cabinet, which they eventually did the following month, on 15 January, before the political trials, electoral irregularities and the attack on the printing press of the party. The January elections gave a small majority to the Party of Smallholders, contrary to the Habsburgs and against the Christian National Union Party, monarchic and favourable to the dynasty. The result augured a future crisis between both tendencies, despite the disinterest of the majority of the population who were impoverished by the condition of the state. On 1 March 1920 and after a lobbying campaign in favour of Horthy and the intimidation of the parliament, they voted overwhelmingly for Miklós Horthy for the new post of regent of the kingdom. Troops loyal to Horthy surrounded the House during the voting. Huszár took the side of Horthy versus those who preferred the return of the king-emperor.
The government was invited to participate in the Paris Peace Conference on 2 December. Both Horthy and Huszár were convinced of the need to sign the peace treaty, the conditions of which were presented to the Hungarian delegation on 16 January. The conference had approved the clauses almost a year before the 26 February 1919, and these were based on the premise of self-determination of minorities, regardless of other criteria such as geographical or economic. The government of Huszár denied that the minorities wished to join neighbouring countries and that they constituted majorities in some of the areas planned to be transferred over to them, and he requested the holding of plebiscites. The peace conference rejected his allegations one month later, and on 6 March confirmed the wording of the treaty. On 14 March 1920, a new coalition government with left and right forces took over, with Sándor Simonyi-Semadam at the front of the new ministry. Huszár had resigned that day so he would not have to sign the peace treaty. During Simonyi-Semadam's rule, the Habsburg dynasty in Hungary remained abolished, Hungary was officially separated from Austria and the head of state became a regent. All the laws promulgated during the Hungarian People's Republic and the Hungarian Soviet Republic were repealed.
After the government
Between 1920 and 1928, he was deputy and vice-president of the Hungarian National Assembly. He then transferred to the Diet. Between 1928 and 1934, he presided over the National Institute of Social Security. He died, after gradually withdrawing from politics, on 29 October 1941 in the capital.
