Do-Aklin or Gangnihessou (Ganye Hessou) or Dogbari was the first of twelve kings of Dahomey in Africa. Gangnihessou might have been the king around the year 1620. One of his symbols was a bird called "gangnihessou" after his name. His other symbols were a drum, and sticks used for throwing or hunting. He had a younger brother called Dakodonou, who was a king. Some historians think Gangnihessou was not actually a king. Instead, Gangnihessou might have led people by giving advice to his brother.
