Suzerainty of Serbia as a hereditary monarchy under its own dynasty was acknowledged de jure in 1830. In 1821, the Greeks declared war on the Sultan. A rebellion that originated in Moldavia as a diversion was followed by the main revolution in the Peloponnese, which, along with the northern part of the Gulf of Corinth, became the first parts of the Ottoman Empire to achieve independence (in 1829). By the mid-19th century, the Ottoman Empire was called the "sick man" by Europeans.

Document 14: Decline and modernization of the Ottoman Empire: The Russo - Turkish War of 1877 -- 1878 had its origins in a rise in nationalism in the Balkans as well as in the Russian goal of recovering territorial losses it had suffered during the Crimean War, reestablishing itself in the Black Sea and following the political movement attempting to free Balkan nations from the Ottoman Empire. As a result of the war, the principalities of Romania, Serbia and Montenegro, each of which had de facto sovereignty for some time, formally proclaimed independence from the Ottoman Empire.
