Luba people
These products attracted interest and demand from far off ethnic groups, creating trade opportunities and traders amongst the Luba people. This trade and all economic activity in the villages of Luba people had a tribute system, where a portion of the hunt, fish or produce was given to the lineage head or the people guarding the borders. These were natural borders, such as that created by waters of Lake Upemba, where passage across required channels and bridges. The movement into and out of the Luba people lands was thus controlled and taxed.
