Ottoman–Habsburg wars The Ottoman–Habsburg wars were fought from the 16th through the 18th centuries between the Ottoman Empire and the Habsburg (later Austrian) Empire, which was at times supported by the Holy Roman Empire, Kingdom of Hungary and Habsburg Spain. The wars were dominated by land campaigns in Hungary (including Transylvania and Vojvodina), Croatia and Central Serbia.
Capture of Mahdiye (1550) The capture of Mahdia was an amphibious military operation that took place from June to September, 1550, during the struggle between the Ottoman Empire and the Spanish Habsburgs for the control of the Mediterranean. A Spanish naval expedition under the command of the Genoese condottiero and admiral Andrea Doria and the Spaniard Bernardino de Mendoza, supported by the Knights of Malta under their Grand Master Claude de la Sengle, besieged and captured the Ottoman stronghold of Mahdia or Mahdiye, defended by the Ottoman Admiral Turgut Reis, known as "Dragut", who was using the place as a base for his piratical activities throughout the Spanish and Italian coasts. Mahdia was abandoned by Spain three years later, and all its fortifications were demolished to avoid a re-occupation of the city by the Ottomans.
