The flag of the now-defunct State of Katanga was designed by an architect Louis Dressen, former manager of Banque du Congo Belge in Elisabethville (modern-day Lubumbashi).
Components of the flag had to represent the motto of Katanga: Force, espoir et Paix dans la Prosperite ("Power, Hope and Peace in Prosperity"). The red component is for power, green for hope, white for peace and the croisettes (saltires/crosses, based on the area's traditional currency, the Katanga cross) for prosperity.
