Why Nambi
She chose to stay.
In the Buganda origin story of Kintu and Nambi, Nambi is the daughter of Ggulu, the sky. When her brothers went home, she chose to stay on earth and decide her own path, and she won her father's consent to marry Kintu. Together they became the mother and father of a people.
Some tellings blame her for letting death follow them to earth when she went back for millet. We tell it differently: she went back to feed her household, and her children outlived death.
Nambi stands for a woman who chooses, whose consent matters, and whose line endures. That is what this movement is built on.
