During the colonial era, there had been other incidents between the people today known as the Banyamulengue and other ethnic groups (the Fulero, for instance), and new waves of migration - either prompted by colonization or spontaneous - had arrived from Rwanda in the Congo (approximately 80,000 people between 1934 and 1954).
