Afterwards, Soliman campaigned through Germany. Ottoman forces recaptured Buda and came to Estergon. Then they had advanced through Austria and Germany. Many towns, cities and castles were conquered in Austria and the campaign took seven months. Austria was ruined after these battles. At last Ferdinand wanted a peace treaty and Charles’ plans to conquer whole Europe had been broken (22^nd July 1533).

Ferdinand never gave up his aims on Hungary. John Zapolya died and his son Sigmund succeeded him. Ferdinand took advantage of this interragnum on the Hungarian throne and besieged Buda again. Consequently, Soliman I had organised another campaign to Hungary with a more powerful army, in 1540. He appointed Sigmund to the principality of Wallachia and he annexed Buda. Soliman Pasha was appointed as the governor of this city. As a result of this campaign, Austria took only northern part of Hungary. The Ottoman-Hungarian relations continued until the death of Sultan Soliman.
