In the Kongo Kingdom and its vassals (Loango, Kakongo, Ngoyo), the woven arts were emblematic of kingship and nobility. The coarse filament stripped from the fronds of the raffia palm tree served as the foundation of the Kongo weaving arts. This material imposed constraints that were overcome to produce varied and ingenious textile formats and structures. Raffia cloth (singular : Lubongo, Libongo, plural : Mbongo; also called Mpusu) was used as currency.[1][2][3][4]
