Very little is known about Do-Aklin and most of it is connected to folklore, but it is generally claimed that he settled a large group of Aja people from Allada on the Abomey plateau amongst the local inhabitants in c. 1620.

His son Dakodonu would eventually build a palace on the plateau and began forming the Kingdom of Dahomey.

Around 1600, three brothers (two in some versions) in the lineage of Agassu fought over the succession to the throne and it was decided that each would settle a new territory.

The agreement was reached at Houégbo that Teagbanlin would found a state at what is now Porto-Novo, another son would take control in Allada, and Do-Aklin would settle on the Abomey plateau to the north.

[2] Do-Aklin's son (or grandson in some versions) Dakodonu became the founder of the palace and the kingdom of Dahomey around 1640 by defeating a local chieftain.
