The three privileges were given to the district in 1759, 1774, and 1800, and were published for those frontiersmen (Serbs) that did not emigrated to Russian Empire or Banat. The first privilege of the District defined its autonomous status, while the second one allowed to ethnic Hungarians to settle in the district. Serbs opposed this settling of Hungarians in Serb settlements and in some places ethnic clashes between the two groups occurred. For example, the first Hungarian house built in Martonoš was demolished by Serbs. The ethnic balance in much of the area was, however, changed in favor of the Hungarians.
