Unlike other Allied leaders, Wilson did not seek territorial gains or material concessions from the Central Powers. His chief goal was the establishment of the League of Nations, which he saw as the "keystone of the whole programme." Wilson himself presided over the committee that drafted the Covenant of the League of Nations, The covenant bound members to respect freedom of religion, treat racial minorities fairly, and peacefully settle disputes through organizations like the Permanent Court of International Justice. Article X of the League Covenant required all nations to defend League members against external aggression. Japan proposed that the conference endorse a racial equality clause; Wilson was indifferent to the issue, but acceded to strong opposition from Australia and Britain. The Covenant of the League of Nations was incorporated into the conference's Treaty of Versailles, which ended the war with Germany. The covenant was also incorporated into treaties with Austria (the Treaty of Saint-Germain-en-Laye), Hungary (the Treaty of Trianon), the Ottoman Empire (the Treaty of Sèvres), and Bulgaria (the Treaty of Neuilly-sur-Seine).
