First of all, in his speech julien is very clear about the motivations for independence. He is one of the representants of the anti-colonialist movement. He say that colonised peoplejust want to be recognize as equals, they are tired of being considered as inferior. They want to "be accpeted by the white man".

Colonised people fell humiliated by the hard work almost forced, thedeculturalisation, they feel humilated by being so dominated that they lost there nationalism. They want their condition and quality of life to be improved, they want to change and to assertthemselves. They revendicate a civic equality and interne autonomy.
