The institutional framework imposed upon Niger in 1946, tended to function according to traditional political concepts, norms, notions and values. Hence the distinction established in this paper between ‘traditionalist’ (UNIS/BNA) and ‘modern’ political parties, refers to the degree of reliance upon this traditional culture and also to the degree to which party-leaders were able to manipulate the norms, notions, etc., of the traditional political systems, in order to gain influence within the new institutional framework. The French Administration, functioning largely as an indigenous chieftaincy, was to a certain extent forced to interfere in politics, since an electoral victory for a ‘modern’ political party (i.e. the évolués) would have to be interpreted—according to the logic of traditional political theory—as a loss of the ‘force’, ‘power’ or ‘luck’, without which the French could no longer be regarded as the legitimate rulers of Niger.If the French finally decided to collaborate with the évolués (and in the process disentangled themselves from the ‘chieftaincy-model’), it was because the évolués constituted the only group capable of grasping the intricate problems of economic development and of running a modern state.
