At the end of the war, the victorious powers sought to divide up the Ottoman Empire. Signed between the Allied and Associated Powers and Ottoman Empire at Sèvres on 10 August 1920, the Treaty of Sèvres promised to maintain the existence of the Armenian republic and to attach the former territories of Ottoman Armenia to it. Because the new borders of Armenia were to be drawn by United States President Woodrow Wilson, Ottoman Armenia was also referred to as "Wilsonian Armenia." In addition, just days prior, on 5 August 1920, Mihran Damadian of the Armenian National Union, the de facto Armenian administration in Cilicia, declared the independence of Cilicia as an Armenian autonomous republic under French protectorate.
