Dagi knot - a Pan African symbol of unity found in several African cultures, i.e., Yoruba, Hausa, Bushongo, etc.

Umoja (Unity) is the first and foundational principle of the Nguzo Saba for without it, all the other principles suffer. Unity is both a principle and practice of togetherness in all things, good and of mutual benet, It is a principled and harmonious togetherness, not simply a being together. This is why value-rootedness is so important, even indispensable. Unity as principled and harmonious togetherness is a cardinal virtue of both classical and general African societies. In ancient Egypt, harmony was a cardinal virtue of Maa, i.e., righteousness, rightness. In fact, one of the ways to translate Maat is to define it as harmony—harmony on the natural, cosmic and social level. Likewise, Cieng among the Dinka, means both morality and harmonious living together. Thus in both ancient Egyptian and Dinka society, one cannot live a moral life without living in harmony with other members of the community.
