Richard Bradshaw; Juan Fandos-Rius (2016). Historical Dictionary of the Central African Republic. Rowman & Littlefield. p. 94.

The arrival of European colonialists at the turn of the 20th century initially provided slave-raiding states with more weapons and this contributed to the depopulation of much of eastern CAR, but the French suppressed slave raiding once they established the colony of Ubangi-Shari. By this time, however, many Banda communities in eastern CAR had disappeared altogether."
