Treaty of Brest-Litovsk
On March 3, 1918, Russia followed the armistice of Erzincan with the Treaty of Brest-Litovsk and left the war. It ceded territory from March 14 to April 1918, when a conference was held between the Ottoman Empire and the delegation of the Seim. Under the Treaty of Brest-Litovsk, the Russians allowed the Turks to retake the Western Armenian provinces, as well as to take over the provinces of Kars, Batum, and Ardahan.
