Cause

Bulgaria fought on the side of the Central Powers in World War I and was among the defeated nations. Following the armistice, the victorious Allied powers convened to draft a series of peace treaties aimed at reducing the military and political strength of the defeated states.

Event

On 27 November 1919, representatives of the Allied powers and Bulgaria signed the Treaty of Neuilly-sur-Seine at the town hall in Neuilly-sur-Seine, France. The treaty required Bulgaria to cede various territories and formed part of a broader set of post-war settlements including the treaties of Versailles, Saint-Germain, Trianon, and Sèvres.

Consequence

Bulgaria was compelled to surrender territories and accept military restrictions. Because the treaty contained the Covenant of the League of Nations, the United States declined to ratify it, consistent with its rejection of the broader post-war peace framework.

Political Outcome

Outcome

Bulgaria ceded territories and accepted military limitations; the treaty diminished Bulgarian political and military power as part of the post-WWI settlement.

Before

Bulgaria as a sovereign Central Power member with pre-war territorial holdings

After

Bulgaria reduced in territory and military capacity under Allied-imposed treaty terms
