Hungary imposed a military administration on the redeemed territories. Between October 28 and 29, 1938, Béla Imrédy and the leader of the United Hungarian Party Andor Jaross made an agreement that representatives of the party who stayed in redeemed territories would be part of a civic group of general staff, which would hold supreme authority. One of its parts (the Upper Country Unification Group) later became the basis for the Ministry for Upper Country, led by Jaross. All other political parties were banned, and obstacles were made for the introduction of other parties from Hungary. The United Hungarian Party then used its power for the persecution of Slovaks as well as Hungarians who had disagreed with the activities against Czechoslovakia before the award. Military administration was changed to civilian on December 21, 1938.
