Kingdom of Romania Trucker Hat
The Kingdom of Romania was the old Romanian state based on a form of parliamentary monarchy between 13 March 1881 and 30 December 1947, specified by the first three Constitutions of Romania (1866, 1923, 1938). Thus, the Kingdom of Romania began with the reign of King Carol I of Romania who gained Romanian's independence in the Romanian War of Independence, and ended with the abdication of King Michael I of Romania in 30 December 1947, imposed by the Soviet Union with the tacit and secret, implicit consent of its allies (as a result of the Yalta Conference and secret agreements). As such, it is quite distinct from the Romanian Old Kingdom, which refers strictly to the reign of King Carol I of Romania, between 13 March 1881 and 10 October 1914. From 1859 to 1877, Romania evolved from a personal union of two vassal principalities (Moldavia and Wallachia) under a single prince to a full-fledged independent kingdom with a Hohenzollern monarchy. In 1918, at the end of World War I, Transylvania, Eastern Moldavia (Bessarabia), and Bukovina united with the Kingdom of Romania, resulting in a "Greater Romania". In 1940, at the beginning of World War II, Northern Transylvania, Basarabia and Cadrilater were ceded to Hungary, the Soviet Union and Bulgaria respectively, only Northern Transylvania being recovered after World War II ended. In 1947 the last king was compelled to abdicate and a republic ruled by the Romanian Communist Party replaced the monarchy.
