Treaty of Bucharest
As a result of the Russian Revolution, Romania was left isolated and unable to continue the war, and was forced to sign the Treaty of Bucharest with the Central Powers. Later on, in 1919, Germany agreed, in the Treaty of Versailles Article 259, to renounce all the benefits provided to it by the Treaty of Bucharest in 1918. After the successful offensive on the Thessaloniki front, which put Bulgaria out of the war, Romania re-entered the war on November 10, 1918, a day before its end in the West.
