full_context: Document 1: Modern history: Italian unification was the political and social movement that annexed different states of the Italian peninsula into the single state of Italy in the 19th century. There is a lack of consensus on the exact dates for the beginning and the end of this period, but many scholars agree that the process began with the end of Napoleonic rule and the Congress of Vienna in 1815, and approximately ended with the Franco-Prussian War in 1871, though the last città irredente did not join the Kingdom of Italy until after World War I.

Document 7: Ottoman Empire: The Serbian revolution (1804–1815) marked the beginning of an era of national awakening in the Balkans during the Eastern Question. 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 11: 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. After almost half a millennium of Ottoman domination (1396 -- 1878), the Bulgarian state was reestablished as the Principality of Bulgaria, covering the land between the Danube River and the Balkan Mountains (except Northern Dobrudja which was given to Romania) and the region of Sofia, which became the new state's capital.
