League of Nations [SEP] Mandatory powers
The territories were governed by mandatory powers, such as the United Kingdom in the case of the Mandate of Palestine, and the Union of South Africa in the case of South-West Africa, until the territories were deemed capable of self-government. Fourteen mandate territories were divided up among seven mandatory powers: the United Kingdom, the Union of South Africa, France, Belgium, New Zealand, Australia and Japan. With the exception of the Kingdom of Iraq, which joined the League on 3 October 1932, these territories did not begin to gain their independence until after the Second World War, in a process that did not end until 1990.
