The occupation of Pécs and Baranja by the Serbian army provoked some resistance from workers who wanted to be connected to revolutionary events taking place at the time in Hungary. After the collapse of the uprising in Hungary, in August 1919, a large number of emigrants took shelter in Pécs. The workers, reinforced by the sudden influx, took over the administration of the city, along with the civilian forces. On 5 August 1921, the Conference of Ambassadors gave instructions for the Yugoslav withdrawal of southern Hungary and asked the Yugoslav government to appoint an officer through whom the local Allied Commission might communicate with Belgrade; Colonel Čolak-Antić was appointed Military Commander of Pécs and Baranja during the transitional period; amongst his duties was the handover of the civilian government in Pecs to the Hungarian authorities. The Yugoslav army started to evacuate Pecs and the Baranja in mid-August.
