CEVAP:

The Ottomans , fighting against the Austrians and the Russians at the same time, signed peace treaties at Nis and Belgrade (1739) thanks to some military successes against the Austrians, strong alliances with Poland and Sweden, and an outbreak of plague devastating the Russian troops. This made it possible for them to reverse some of the losses of Passarowitz. Austria and Russia left the Ottomans alone for a while, since they had to deal with a new rising power: Prussia.
