added those of Negropont, Thebes, and Dalmatia, until by 1694 the Turks were stripped of all their posessions in Greece and on the coast of the Adriatic. [Sidenote: =Mustafa Kiuprili grand vizier, 1688.=] So continuous a series of misfortunes demanded a victim. In 1688 a palace revolution replaced Mohammed IV. by his brother Suleiman II., and the new Sultan once more intrusted the affairs of the empire to a Kiuprili. Mustafa Kiuprili, the brother of Achmet, showed the vigour of character for which his family were noted. By pursuing a policy of toleration for the Christians and restoring stern discipline to the army, he was soon enabled to bring victory back to the Turkish standards, although he was but two years in his office. In 1690 he recovered Nisch and Belgrade and invaded Hungary, but he was met, defeated, and killed by the margrave of Baden at the battle of Szcelankemen in 1691. With him perished the last chances of the Turks. Although the war continued for eight years with varying success the imperialists and the Venetians never really lost their hold upon Hungary, Transylvania and the Morea. In 1697 prince Eugene won one of the greatest of his victories over Sultan Mustafa II. in person, at Zenta, and Peter the Great marked the first serious entrance of Russia into the politics of south-eastern Europe by the capture of Azof. The Sultan realised that with the Kiuprili the possibility of fresh conquests had passed away, and he must content himself with the boundary of the Danube. [Sidenote: =The peace of Carlowitz, 1699.=] By the peace of Carlowitz, concluded in January 1699, the Emperor recovered the whole of Hungary, except the district of Temesvar, the larger part of Croatia and Sclavonia, and the suzerainty over Transylvania. Poland retained Podolia, including Kaminiec, and Russia Azof, while the Morea fell to Venice. Thus the Turkish frontier was practically reduced to the Danube, and the seeds of the Eastern Question were sown in the decay of the Ottoman empire and the advance of Russia, and a new epoch in the history of south-eastern Europe began.
