The Treaty of Küçük Kaynarca (Turkish: Küçük Kaynarca Antlaşması; Russian: Кючук-Кайнарджийский мир), formerly often written Kuchuk-Kainarji, was a peace treaty signed on 21 July [O.S. 10 July] 1774, in Küçük Kaynarca (today Kaynardzha, Bulgaria) between the Russian Empire and the Ottoman Empire, ending the Russo-Turkish War of 1768–1774 with major concessions to Russia. The concessions to Russia were not merely territorial; not only was the Crimean Khanate (not Crimea proper) effectively ceded to Russia, but Russia also gained the right to construct a Russian Orthodox church in Constantinople, claiming to be the protector of the Orthodox Christians in the Ottoman Empire. This was a pretext for frequent and numerous interventions in the decades to follow. Ottoman Christians started to feel more empowered as European and Christian powers demonstrated their rising influence and political power.
