At the end of world war one, the ottoman empire was reduced to the area of turkey

The statement you show is TRUE

Explanation:

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.

The League of Nations created a system for governing former German and Ottoman territories, called "the mandate system."  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.  There were mandate territories in Africa and Asia, as well as the Middle East.  As an example, 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.
