The Russo-Turkish War of 1768–1774 was a decisive conflict that brought Southern Ukraine, Crimea and the upper northwestern part of the North Caucasus within the orbit of the Russian Empire. Though the victories accrued by the Russian Empire were substantial, they gained far less territory than otherwise would be expected. The reason for this was the complex struggle within the European diplomatic system for a balance of power that was acceptable to other European leading states, rather than Russian hegemony. Russia was able to take advantage of the weakened Ottoman Empire, the end of the Seven Years' War, and the withdrawal of France as the continent's primary military power (due to financial burden and isolationism). This left the Russian Empire in a strengthened position to expand its territory but also lose temporary hegemony over the decentralized Poland. The greater Turkish losses were diplomatic in nature seeing its full decline as a threat to Christian Europe, and the beginning of the Eastern Question that would plague the continent until the end of the Ottoman Empire in the 20th century.
