Colonies and mandates, along with protectorates, belong to the wider group of ‘dependent’ territories. Colonies were under the total control of a foreign power which decided all aspects of the administrative, executive and legislative organisation. Public international law was mainly relevant for slavery, forced labour and ‘open-door’ policies. The mandates system was certainly inspired by colonialism, especially in the eyes of contemporaries, for whom colonialism was the ‘white man’s burden’ for the benefit of ‘uncivilised peoples’. However, it also had fundamental structural differences: their purpose – the ‘civilising mission’ – and the triangular relationship (League of Nations, territory, mandate), stand in sharp contrast to the colonial institution. In addition, the mandatory power was not the holder of sovereignty over the mandated territory. The triangular relationship refers particularly to the control that is supposed to embody it. The control exercised by the League marks a notable difference from the colonial system, establishing for the first time in the history of international relations a sophisticated form of indirect international administration of territories.
