The Treaty of Karlowitz was signed on 26 January 1699 in Sremski Karlovci, in modern-day Serbia, concluding the Austro-Ottoman War of 1683–97 in which the Ottoman side had been defeated at the Battle of Zenta. It marks the end of Ottoman control in much of Central Europe and the beginning of the empire's phase of decline, with their first major territorial losses after centuries of expansion, and established the Habsburg Monarchy as the dominant power in Central and southeast Europe.
