Why did russia sypported ibdepebdence of ottoman empire???

Russia did not support the independence of the Ottoman Empire. In fact, Russia had a long history of conflict with the Ottoman Empire and sought to weaken and eventually disintegrate it. The Ottoman Empire was seen as a rival to Russian expansion in the Balkans and the Caucasus region. Russia supported various nationalist movements within the empire, such as the Greeks, Serbs, and Bulgarians, who sought independence from Ottoman rule. This was part of Russia's broader strategy to weaken the Ottoman Empire and expand its own influence in the region.
