The Guinean borders, a pure product of colonization, were established with the consent of international conventions between powerful nations, but also the administrative acts taken within the framework of the internal organization in the French Western African territories, from the end of 19th to the beginning of the 20th century. Their institutionalization intaures a new lifestyle and practices that they imposed in the border communities. Starting from second half of the 20th century, the socio-political and economic instability that the world knew, cause the awakening of conscience of the colonized people, eager to take over their own destiny. In this African and world context, Guinea was made conspicuous by its political choice and gained its independence on October 2nd, 1958. The new State, in spite of many challenges to take up, also has been confronted with the tricky management of new borders inherited from the colonial period, and captured by intercommunity conflicts which emerged from the years 1970, and which still remain in the system.
