Romania (Romanian: România) is a country in Southeastern Europe. It shares a border with Hungary and Serbia to the west, Ukraine and the Republic of Moldova to the northeast, and Bulgaria to the south. Romania has a stretch of sea coast along the Black Sea. It is located roughly in the lower basin of the Danube and almost all of the Danube Delta is located within its territory.
Romania is a semi-presidential unitary state. As a nation-state, the country was formed by the merging of Moldavia and Wallachia in 1859 and it gained recognition of its independence in 1878. Later, in 1918, they were joined by Transylvania, Bukovina and Bessarabia. At the end of World War II, parts of its territories (roughly the present day Moldova) were occupied by USSR and Romania became a member of Warsaw Pact. With the fall of the Iron Curtain in 1989, Romania started a series of political and economic reforms that peaked with Romania joining the European Union.

Its capital and largest city is Bucharest (Romanian: Bucure┼čti ), the sixth largest city in the EU with almost 2.5 million people. In 2007, Sibiu, a large city in Transylvania, was chosen as European Capital of Culture. Romania joined NATO on March 29, 2004, and is also a member of the Latin Union, of the Francophonie and of OSCE.
