The interests of the three neighbouring great powers — the Habsburg Monarchy, the Ottoman Empire, and the Polish–Lithuanian Commonwealth — were damaged by Michael the Brave's achievements. Although he acknowledged the suzerainty of Rudolf II, Michael the Brave continued to negotiate his official position in Transylvania, pleading for direct rule instead of being imperial governor. Michael kept the control of all three provinces for less than a year before the Hungarian nobility of Transylvania rose against him in a series of revolts with the support of the Austrian army commanded by Italian General Giorgio Basta, defeating Michael the Brave at the Battle of Mirăslău, forcing the prince to leave Transylvania and retreat to Wallachia with his remaining troops, while the forces of the Polish–Lithuanian Commonwealth entered Moldavia and defeated the forces loyal to Michael the Brave, restoring Ieremia Movilă on the throne. The Polish army led by Jan Zamoyski also advanced in eastern Wallachia and established Simion Movilă as ruler. Forces loyal to Michael remained only in Oltenia.
