The Ottomans retained Belgrade, the Banat of Temesvár (modern Timișoara), as well as suzerainty over Wallachia and Moldavia. Negotiations with Tsardom of Russia for a further year under a truce agreed at Karlowitz culminated in the Treaty of Constantinople of 1700, whereby the Sultan ceded the Azov region to Peter the Great. (Russia had to return these territories eleven years later following the failed Pruth River Campaign and the Treaty of the Pruth in 1711.)
