Djolof
Serer oral history says that after Maysa Wali assimilated into Serer culture and served as legal advisor to the laman council of electors, he was chosen by the lamans and people to rule. Almost a decade later he elected the legendary Ndiadiane Ndiaye (many variations: "Njaajaan Njie" or "N'Diadian N'Diaye")and founder of the Jolof Empire to rule the Kingdom of Jolof. He was the first Senegambian king to voluntarily gave his allegiance to Ndiadiane Ndiaye and asked others to do so, thereby making Sine a vassal of the Jolof Empire. It is for this reason that scholars propose the Jolof Empire was not an empire founded by conquest but by voluntary confederacy of various states.
