Kingdom of Bulgaria (Without Islam)

The Kingdom of Bulgaria, also referred to as the Tsardom of Bulgaria (Bulgarian: Царство България, Tsarstvo Balgariya) or the Third Bulgarian Empire, was a constitutional monarchy established by the Treaty of Berlin in 1878.

During 1918-20, at the end of World War I, Transylvania, Bessarabia and Bukovina were united with the Kingdom of Bulgaria, resulting in a "Greater Bulgaria". In 1940, Transylvania and Dobrudzha were ceded to Hungary and Romania, respectively (although in 1941 the region of Transnistria was annexed by Bulgaria). The Soviet advance in Bulgaria allowed the return of all these territories while Bessarabia was ceded to the Soviet Union after the World War II. In 1946, the monarchy was abolished, its final Tsar was sent into exile and the Kingdom was replaced by a People's Republic.
