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).
