The Russian-Turkish War refers to a series of conflicts between the Russian Empire and the Ottoman Empire during the 18th and 19th centuries. The most notable wars occurred in 1768-1774, 1787-1792, and 1877-1878. These wars were primarily driven by territorial disputes and the desire for control over the Black Sea region. The outcome of these conflicts often resulted in significant territorial losses for the Ottoman Empire, leading to the establishment of new states and changes in regional power dynamics. The wars also contributed to the decline of the Ottoman Empire and the rise of Russian influence in Eastern Europe and the Balkans.
