Who was the morho naba in the Mossi state of Ouagadougou?

The term morho naba (meaning "big lord") refers to the title of the paramount ruler of the Mossi people, rather than the name of a specific individual.1

The morho naba holds his seat at Ouagadougou, which was the center of one of the independent Mossi states in what is now Burkina Faso. Within this feudal hierarchy, the morho naba is supported by divisional chiefs who serve as his advisers and participate in the selection of his successor, which is typically his eldest son.21
