An
international organization which was created after the First World War to
provide a forum for resolving international disputes was known as League of
Nations. It was headquartered in Geneva, Switzerland. It stopped border
disputes turning into wars. It solved the
border dispute between Iraq and Turkey. Turkey was claiming Mosul situated in Iraq
as its own part. But when the League rejected Turkey’s claim to Mosul, Turkey
agreed.
