When Selim III ascended the throne the Ottoman Empire was in war with Russia and Austria. He continued to struggle with these two states. The basic reason of this war was to save Crimea and hinder Austria planning to divide the Ottoman territories. Crimea’s geopolitical condition was very significant for the safety of Istanbul. During these wars, Ismail Triumph was won against Austria but Russia defeated the Ottoman Army nearly in every front. In Foksan (1st August 1789) and in Boze (22nd September 1789) wars the Ottoman Army was defeated. With these victories Russia invaded the Castle of Akkerman and Baserebya Region. On the other hand, the Austrians invaded Sebes, Muhadiye, Lazarethane and Pancova, afterwards, they occupied Belgrade and Semendire.
