Kingdom of Bulgaria

The Kingdom of Bulgaria, officially the Tsardom of Bulgaria, was a country in Southeastern Europe.

History
Bulgaria was first created as the Principality of Bulgaria. In 1908, he broke apart from the Ottoman Empire.

Then, in WW1, he joined the Central Powers when they promised to make his wildest dreams come true. However, he surrendered in 1918, with the other Central Powers, ending the Great War.

He later joined the Axis Powers in WW2, but surrendered to the Soviet Union after it took over most of his land. Shortly after, the war ended, and the Soviet Union turned Bulgaria communist, ending the Kingdom of Bulgaria's life.
