-Class A comprised territories that were formerly part of the Ottoman Empire and were sufficiently advanced for their independence to be “provisionally recognized.” It was subject to the administrative advice and assistance of the Mandatory, “until such time as they were able to stand alone.” Except Iraq (Mandatory—Great Britain), which achieved early independence, all the territories under this category—Palestine and Transjordan (Mandatory—Great Britain), Syria and Lebanon (Mandatory—France) became independent only after the Second World War.

-Class C mandates were the least-developed. Because of their sparse population or small size, or remoteness from the centers of civilization, or their geographical continuity to the territory of the Mandatory, they were administered under the laws of the Mandatory as integral portions of its territory. The territories concerned were: Nauru (Mandatory powers were Great Britain, Australia, and New Zealand), New Guinea (Mandatory—Australia), Western Samoa (Mandatory—New Zealand), Pacific Islands north of the Equator (Mandatory— Japan), South-West Africa (Mandatory—South Africa).
