When Michael entered Transylvania, he did not immediately free or grant rights to the Romanian inhabitants, who were primarily peasants but, nevertheless, constituted a significant proportion of the population. Michael demonstrated his support by upholding the Union of the Three Nations, which recognized only the traditional rights and privileges of the Hungarians, Székelys and Saxons, but he didn't recognize the rights of the Romanians. Indeed, while he brought some of his Wallachian aides to Transylvania, he also invited some Székelys and other Transylvanian Hungarians to assist in the administration of Wallachia, where he wished to transplant Transylvania's far more advanced feudal system.
