The Treaty of Adrianople of 1568 or Treaty of Edirne of 1568, named after the Ottoman city of Adrianople (present-day Edirne), and signed on 17 February 1568 between Maximilian II and Selim II. It concluded the Austrian-Turkish War (1566-1568) after Battle of Szigetvár, and brought a period of 25 years of (relative) peace between both Empires.
Maximilian's ambasadors Croatian Antun Vrančić and Styrian Christoph Teuffenbach had arrived in Istanbul on 26 August 1567. Serious discussions with Sokollu Mehmed Pasha presumably began after the ambasadors' ceremonial audience with Selim II. After five months negotiations, agreement had been reached by 17 February, and the Treaty of Adrianople was signed on 21 February 1568, ending the war between the Austrian and Ottoman empires. The Habsburg Holy Roman Emperor, Maximilian II, agreed to pay an annual "present" of 30,000 ducats and essentially granted the Ottomans authority in Transylvania, Moldavia and Walachia.
