My book entitled "The origins of the genocide of the Tutsi and its barbaric execution" is a socio-political analysis that proves that the genocide that we have known in Rwanda is not a fact due to historical hazard, but that it has long-standing origins for which the Catholic Church and the Belgian colonizer are responsible by their actions to sow the confrontation between the Hutu and Tutsi ethnic groups. The most dreadful means they have used are : The ethnic segregation in schools, the promotion of chiefs who brutalized the modest population, the ethnic confrontation that led to the 1960 troubles that caused the Tutsi refugees of 1960, who returned to the Country by the 1990 to 1994 war and its consequences on the population and the Country in general. This considerable tension thus created led to the genocide gradually and in 1994 it was honor and barbarism that covered the hills of Rwanda.
