Excerpts from Books and Wikipedia
"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." [Wikipedia] "On 11 September 1697, or nine days before the first of the Ryswick treaties was signed, an Austrian army of about 50,000, commanded by Prince Eugène of Savoy, defeated a Turkish army twice that number and commanded by Sultan Mustafa II in person, at Zenta in central Hungary. So crushing was the victory–one of the most complete in the history of European warfare–that it effectively ended the centuries-old struggle between Habsburg and Turk for the domination of Hungary."
