The mandate system affect the Middle East
Mandate system is the League of nations pigeonholed the previous German and Ottoman regions based on whence available they were to rule themselves. The mandate system sustained European colonialism although they guarantee middle eastern countries freedom.
The mandate system provided European authorities, especially Britain and France, continued domination over the Middle East. This enraged many Arabs, who presumed promises for self-sovereignty to be satisfied after their assistance on the side of the Allies in World War I. The league of nations said that the middle east was nearly able to administer themselves.
