History

First joined to modern Bulgaria at its restoration as a state in 1878, it was a part of Romania from 1913 until 1940. In 1940, the Nazi Germany imposed Romania in the Treaty of Craiova to cede it to Bulgaria with a population exchange (the Romanian minority was forced to leave the south while the Bulgarian minority had to leave the north).
