ABSTRACT : Contrary to the thought of common meaning which says that, tradition is synonymous with fixism, a socio-historical and anthropological approach demonstrate that the tradition is sensitive to the change, or evolution.It is by remaining in the concrete case of the Bafou traditional kingdom, like others Bamileke traditional kingdom of Cameroon that we realise that, the sociopolitical structure like the MENDZONGS for instance, after their creation because of many task assigned by the kingdom and especially for the ancient tribal war, they havn’t remained unchangeable, but rather dynamic. Despite of the disappearance of endemic war, which was their raison d’etre, further to the advent of modernity, the MENDZONGS have reconstructed, reorganised their selves under duress of state modernity and became really the bedrock of development and selfdevelopment through the solving of Bafou grouping problems, through intervention in many domains such as financial, material or physical. This testify the sense of their permanent and perpetual dynamism due to the fact that these structures found their selve in a dual dialectic of destruction and reconstruction, because they have being first of all composed by historical positions, then decomposed and latest recomposed, which goal aim at surviving and adapt to mutation and social changes in other to be a current event, to sustain their traditional army and kingdom’s sociopolitical statut in this period of modernity.
