Answer: The mandate system authorized a member nation of the League of Nations to govern a former German or Turkish colonial area after the conclusion of World War I.
Context/detail:
When World War I erupted, the Ottoman Empire sided with Germany as part of the "Central Powers." In the end, the Central Powers lost and the Turkish empire of the Ottomans ceased to exist as an empire. Turkey remained as a country, but it lost control over other territories that it had held before. Germany was stripped of its overseas colonial holdings.
The League of Nations created a system for governing former German and Ottoman territories, called "the mandate system." There were mandate territories for former German territories in Africa and Asia, as well for former Ottoman territories in the Middle East.
The former Turkish provinces of Syria, Iraq and Palestine in the Middle East were divided into a French mandate territory and British mandate territory. The British mandate rule over Palestine has much to do with the history of the development of the Arab-Israeli conflict.
I believe your answer to this is the Nubian civilization.
The Treaty of Versailles, signed in June 1919 at the Palace of Versailles in Paris at the end of World War I, codified peace terms between the victorious Allies and Germany. The Treaty of Versailles held Germany responsible for starting the war and imposed harsh penalties in terms of loss of territory, massive reparations payments and demilitarization. Far from the “peace without victory” that U.S. President Woodrow Wilson had outlined in his famous Fourteen Points in early 1918, the Treaty of Versailles humiliated Germany while failing to resolve the underlying issues that had led to war in the first place. Economic distress and resentment of the treaty within Germany helped fuel the ultra-nationalist sentiment that led to the rise of Adolf Hitler and his Nazi Party, as well as the coming of a World War II just two decades later.In a speech to Congress in January 1918, Wilson laid out his idealistic vision for the post-war world. In addition to specific territorial settlements based on an Entente victory, Wilson’s so-called Fourteen Points emphasized the need for national self-determination for Europe’s different ethnic populations. Wilson also proposed the founding of a “general association of nations” that would mediate international disputes and foster cooperation between different nations in the hopes of preventing war on such a large scale in the future. This organization eventually became known as the League of Nations.
