The unsuccessful Tudor Vladimirescu's rebellion in 1821 was followed by the Revolutions of 1848 in Moldavia, Wallachia, and Transylvania which sought complete independence for the first two and national emancipation in the third. These goals were unfulfilled, but were the basis of the subsequent revolutions. The Great Powers did not support the Romanian elites' expressed desire to unite in a single state, forcing Romania to proceed alone against the Turks. The electors in both Moldavia and Wallachia chose the same person - Alexandru Ioan Cuza - as prince. Thus, Romania was created as a personal union, albeit a Romania that didn't include Transylvania, where Romanian nationalism inevitably ran up against Hungarian nationalism. For some time yet, Austria-Hungary, especially under the Dual Monarchy of 1867, would keep the Hungarians firmly in control, even though in Transylvania Romanians constituted an absolute majority. In 1861 the Transylvanian Association for the Literature and Culture of the Romanians was founded in Sibiu, protected by an uncommonly enlightened local government composed largely of Transylvanian Saxons.
Background
The Greek uprising was supported by the Wallachian uprising of 1821. The movement, which was started about the same time by the ennobled peasant, Tudor Vladimirescu, for the emancipation of the lower classes, soon acquired, therefore, an anti-Greek tendency. Vladimirescu was executed by the Etaireía; the latter were completely checked by the Turks, who, grown suspicious after the Greek rising and confronted with the energetic attitude of the Romanian nobility, consented in 1822 to the nomination of two native boyars, Ioniţă Sandu Sturdza and Grigore IV Ghica, recommended by their countrymen, as princes of Moldavia and Wallachia, respectively. The iniquitous system of 'the throne to the highest bidder' had come to an end. The Phanariote regime in Wallachia and Moldavia ended after the uprising of 1821. The 1829 Treaty of Adrianople, was settled between Russia and the Ottoman Empire. Turkey gave Russia access to the mouths of the Danube and additional territory on the Black Sea, opened the Dardanelles to all commercial vessels, commerce is liberated for cereals, livestock and wood, granted autonomy to Serbia, promised autonomy for Greece, and allowed Russia to occupy Moldavia and Walachia until Turkey had paid a large indemnity. The Crimean War was provoked by Russian tsar Nicholas I's continuing pressure on the dying Ottoman Empire, and by Russia's claims to be the protector of the Orthodox Christian subjects of the Ottoman sultan. Britain and France became involved in order to block Russian expansion and prevent Russians from acquiring control of the Turkish Straits and eastern Mediterranean. Russia was defeated in the Crimean War. The peace Congress in Paris decided that Wallachia and Moldavia, which had been under Ottoman suzerainty, were now placed under the collective guarantee of the seven powers that signed the Paris peace treaty. These powers then declared that local assemblies be convened to decide on the future organisation of the two principalities. The Treaty of Paris also stipulated: the retrocession to Moldavia of Southern Bessarabia, which had been annexed in 1812 by Russia ; freedom of sailing on the Danube; the establishment of the European Commission of the Danube; the neutral status of the Black Sea. As a result, Wallachia and Moldavia both elected Alexandru Ioan Cuza in 1859 as their prince, creating a personal union. This personal union was turned into a state union, named Romania, which in 1866 adopted prince Carol from the Hohenzollern-Sigmaringen family as its monarch.
