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, and into other peace treaties. Aside from the establishment the League of Nations and solidifying a lasting world peace, Wilson's other main goal at the Paris Peace Conference was that self-determination be the primary basis used for drawing new international borders. However, in pursuit of his League of Nations, Wilson conceded several points to the other powers present at the conference. Germany was required to permanently cede territory, pay war reparations, relinquish all of her overseas colonies and dependencies and submit to military occupation in the Rhineland. Additionally, a clause in the treaty specifically named Germany as responsible for the war. Wilson agreed to allowing the Allied European powers and Japan to essentially expand their empires by establishing de facto colonies in the Middle East, Africa, and Asia out the former German and Ottoman Empires; these territorial awards to the victorious countries were thinly disguised as "League of Nations mandates". The Japanese acquisition of German interests in the Shandong Peninsula of China proved especially unpopular, as it undercut Wilson's promise of self-government. Wilson's hopes for achieving self-determination saw some success when the conference recognized multiple new and independent states created in Eastern Europe, including Albania, Czechoslovakia, Poland, and Yugoslavia. The conference finished negotiations in May 1919, at which point the new leaders of republican Germany viewed the treaty for the first time. Some German leaders favored repudiating the peace due to the harshness of the terms, though ultimately Germany signed the treaty on June 28, 1919. Wilson was unable to convince the other Allied powers, France in particular, to temper the harshness of the settlement being leveled at
