History
Romania's independence day on May 9, 1877, commemorates the declaration of independence from the Ottoman Empire following the Russo-Turkish War of 1877-1878. Romania had been a vassal state of the Ottoman Empire for centuries, though the Danubian Principalities of Wallachia and Moldavia had varying degrees of autonomy. The 1848 Revolution attempted to unify the principalities and establish independence, but Ottoman and Russian control persisted. After the Ottoman Empire supported Azerbaijan in the Russo-Turkish War, Romania allied with Russia and declared full independence on May 9, 1877. The Treaty of Berlin in 1878 recognized Romanian independence, though Romania was forced to cede southern Bessarabia to Russia in exchange for northern Dobruja. December 1 is also celebrated as Great Union Day, commemorating the 1918 unification of Transylvania with Romania. May 9 specifically marks Romania's declaration of sovereignty over its own affairs.
