NOTES:
German-Micronesia includes the Mariana Islands except Guam, the Palau Islands, the Caroline Islands, the Marshall Islands and Nauru.
With the exception of the German Kiaochow Territory and the Kionga Triangle all German overseas possessions became mandates of the League of Nations in 1920.
Togo and Cameroon became Class B mandates with France and the United Kingdom as mandate holder respectively.
Tanganyika and Ruanda-Urundi became Class B mandates with the United Kingdom and Belgium as mandate power respectively.
German South West Africa, German-Micronesia north of the equator and German Samoa were placed as Class C mandates under the authority of the Union of South Africa, Japan and New Zealand respectively.
Nauru as Micronesia south of the equator became a Class C mandate of Australia, New Zealand and the United Kingdom as joint mandate powers.
The rest of German New Guinea (Emperor William Land, Bismarck Archipelago and the German Solomon Islands) was converted into a Class C mandate administered by Australia.
In 1947 these mandates became United Nations Trust Territories until attainment of independence. In the same year solely Japan’s mandate was replaced by a United States administered United Nations Trust Territory of the Pacific Islands (TTPI). 
No provision is made for an independence of the Northern Mariana Islands. Since 1990 these islands are linked in Political Union with the United States as the Commonwealth of the Northern Mariana Islands.
The transfer of the German overseas possessions was established under the terms of the Treaty of Versailles of 28 June 1919, which went into effect on 10 January 1920.
