Treaty of Neuilly-sur-Seine
Neuilly-sur-Seine town hall, Hauts-de-Seine, France
What happened
Bulgaria and the Allied powers of World War I signed the treaty. Bulgaria had fought on the losing side in World War I. In the town hall of Neuilly near Paris, it agreed to give up Western Thrace, land on its western border and Dobruja. Its army was cut to 20,000 men, and it had to pay large reparations.
Why it matters
Why it matters: Bulgaria lost its outlet to the Aegean Sea. In Bulgaria the treaty is remembered as the 'Second National Catastrophe'.
What came next
Bulgaria won back Southern Dobruja in 1940. A population exchange with Greece was also arranged.
Did you know?
The treaty included the Covenant of the League of Nations, which is why the United States signed but never ratified it.
