Treaty of Paris (1856) in the context of "Ottoman Reform Edict of 1856"

At the Congress of Berlin (13 June – 13 July 1878), the major European powers revised the territorial and political terms imposed by the Russian Empire on the Ottoman Empire by the Treaty of San Stefano (March 1878), which had ended the Russo-Turkish War of 1877–1878. The Congress was the result of escalating tensions; particularly British opposition to Russian hegemony over the Ottoman Empire in the Balkans, through the creation of a Russian-aligned 'Greater Bulgaria'. To secure the European balance of power in favour of its splendid isolation achieved after the Crimean War, Britain stationed the Mediterranean Fleet near Constantinople to enforce British demands. To avoid war, Otto von Bismarck, Chancellor of the newly formed German Empire, was asked to mediate a solution that would restore the Ottoman Empire's position as a counterbalance to Russian influence in the Mediterranean and the Balkans, in line with the principles of the 1856 Treaty of Paris.

Attended by delegates from Europe's then six great powers: Russia, Great Britain, France, Austria-Hungary, Italy, and Germany; the Ottomans as well as representatives of four Balkan states (Greece, Serbia, Romania and Montenegro), the Congress culminated in the Treaty of Berlin (13 July 1878). This agreement essentially dismantled the autonomous Greater Bulgarian State envisaged at San Stefano, and reorganised the borders of south-eastern Europe. The main results were the Austro-Hungarian forcible occupation of Bosnia and Herzegovina, the British de facto annexation of Cyprus under false pretenses, and the formal recognition of the self-declared independence of Romania, Serbia and Montenegro; allies of Russia in the previous war. While the settlement averted war, it exacerbated nationalist grievances in the Balkans and deepened the rivalry between Britain and Russia (The Great Game), contributing to long-term regional instability that foreshadowed the Balkan Wars and World War I.

The Romanian Old Kingdom (Romanian: Vechiul Regat or just Regat; German: Regat or Altreich) is a colloquial term referring to the territory covered by the first independent Romanian nation state, which was composed of the Romanian Principalities: Wallachia and Moldavia. The union of the two principalities was achieved when, under the auspices of the Treaty of Paris (1856), the ad hoc Divans of both countries, which were then under Ottoman Empire suzerainty, voted for Alexander Ioan Cuza as their prince. This process achieved a de facto unification under the name of the United Principalities of Moldavia and Wallachia. The region itself is defined by the result of that political act, followed by the Romanian War of Independence, the inclusion of Northern Dobruja and the transfer of the southern part of Bessarabia to the Russian Empire in 1878, the proclamation of the Kingdom of Romania in 1881, and the annexation of Southern Dobruja in 1913.

The term came into use after World War I, when the Old Kingdom became Greater Romania, after including Transylvania, Banat, Bessarabia, and Bukovina. The term now has mainly a historical relevance and is otherwise used as a common term for all regions in Romania included in both the Old Kingdom and the present borders (Wallachia, Moldavia, and Northern Dobruja).

Mehmed Emin Âlî Pasha, also spelled as Mehmed Emin Aali (5 March 1815 – 7 September 1871), commonly known as Ali Pasha, was a Turkish–Ottoman statesman during the Tanzimat period, best known as the architect of the Ottoman Reform Edict of 1856, and for his role in the Treaty of Paris (1856) that ended the Crimean War. From humble origins as the son of a doorkeeper, Âli Pasha rose through the ranks of the Ottoman state and became the Minister of Foreign Affairs for a short time in 1840, and again in 1846. He became Grand Vizier for a few months in 1852. Between 1855 and 1871 he alternated between the two jobs, ultimately holding the position of Foreign Minister seven times and Grand Vizier five times in his lifetime. Âli Pasha was widely regarded as a deft and able statesman, and often credited with preventing an early break-up of the empire.

Âli Pasha advocated for a western style of reform to modernize the empire, including secularization of the state and education and improvements to civil liberties. He advocated for an Ottoman nationalism that would replace diverse ethnic and religious loyalties. To that end, non-Muslims started to serve in government, with a couple becoming cabinet ministers. In foreign policy, following the Crimean War the Ottoman Empire joined the Concert of Europe. Troops were withdrawn from Serbia, and the Cretan revolt was suppressed. His egalitarian reforms, dealings with Christian powers, and increasingly authoritarian regime were not without controversy, opponents of which coalesced around the Young Ottomans. After his death in 1871, a period of chaos resulted as reactionaries took control over the government, leading to the Great Eastern Crisis.

The Danubian Principalities (German: Donaufürstentümer, Russian: Дунайские княжества, Romanian: Principatele Dunărene) was a geopolitical term used for the Ottoman vassal principalities of Moldavia and Wallachia in the period of 1774–1858, a time of when the territories were a battleground between the Ottoman Empire, Habsburg Monarchy, and Russian Empire. While Russia returned Moldavia and Wallachia to the Ottoman Empire with the Treaty of Küçük Kaynarca (1774), it retained protectorship over the two and also of the Orthodox subjects in all of the Ottoman Empire. This made the two principalities have the status of dual authority, under Ottoman suzerainty but with Russian protection. The Russo-Turkish War (1828–1829) ended with the Russian occupation of the two principalities. The negotiations of the Great Powers in the aftermath of Russian defeat resulted in the unification of Moldavia and Wallachia in 1859.

The two ad hoc divans were legislative and consultative assemblies of the Danubian Principalities (Moldavia and Wallachia), vassals of the Ottoman Empire. They were established by the Great Powers under the Treaty of Paris. By then, the Crimean War had taken the two states out of Russia's sphere of influence, and had nullified the Moldo-Wallachian Regulamentul Organic regime. Officially, the two assemblies were provisional replacements for the traditional assemblies, the Sfaturi (or Divanuri). The term "divan", is derived from the Ottoman rule, being the name of a high governmental body in a number of Islamic states.

The elections for the two Divans confronted two local movements: the National Party, which supported the unification of Moldavia and Wallachia, as "Romania"; the anti-unionists, which sought to maintain the status quo. The National Party emerged as the victor in 1859, when its candidate Alexandru Ioan Cuza was crowned Domnitor over both countries. The resulting United Principalities were the political embryo of modern Romania.
