Cause → Event → Consequence

Cause

Russia's unilateral withdrawal from World War I left Romania isolated on the Eastern Front. After the failed 1917 campaign, the Central Powers issued an ultimatum to King Ferdinand I in February 1918. Following a three-day Crown Council debate in Iași, Romania agreed to negotiate despite strong opposition from Queen Marie and General Constantin Prezan.

Event

Prime Minister Alexandru Marghiloman signed the Treaty of Bucharest on 7 May 1918 at Cotroceni Palace. Under its terms, Romania ceded all of Dobruja to Bulgaria, accepted border adjustments favoring Austria-Hungary, demobilized at least eight divisions, and permitted Central Powers troop transit through Moldavia and Bessarabia toward Odessa.

Consequence

The treaty was ratified by both chambers of the Romanian parliament but was never signed by King Ferdinand, leaving it constitutionally ambiguous. Romania's eventual re-entry into the war in late 1918 and the subsequent Allied victory rendered the treaty void, allowing Romania to reclaim lost territories and achieve significant postwar territorial expansion.

Political Outcome
