The view that the "jambur" (or "jambuur") caste were among the lower echelons of society is a matter of debate. The "jaraff", who was the most important person after the king (Maad a Sinig or Maad Saloum) came from the jambur caste. The Jaraff was the equivalent of a prime minister. He was responsible for organising the coronation ceremony and for crowning the Serer kings. Where a king dies without nominating an heir (buumi), the Jaraff would step in and reign as regent until a suitable candidate can be found from the royal line. The noble council that was responsible for advising the king was also made up of jamburs as well as the "bur kuvel/guewel" (the chief griot of the king) who was extremely powerful and influential, and very rich in land and other assets. The buur kevel who also came from the griot caste were so powerful that they could influence a king's decision as to whether he goes to war or not. They told the king what to eat, and teach them how to eat, how to walk, to talk and to behave in society. They always accompany the king to the battlefield and recount the glory or bravery of his ancestors in battle. They retain and pass down the genealogy and family history of the king. The bur Kevel could make or break a king, and destroy the entire royal dynasty if they so wish. The abdication of Fakha Boya Fall from the throne of Saloum was led and driven by his own bur kevel. After being forced to abdicate, he was chased out of Saloum. During the reign of Sanou Mon Faye – king of Sine, one of the key notables who plotted to dethrone the king was the king's own bur kevel. After influencing the king's own estranged nephew Prince Semou Mak Joof to take up arms against his uncle, the Prince who despised his uncle took up arms with the support of the bur kevel and other notables. The Prince was victorious and was crowned Maad a Sinig (King of Sine). That is just a sample of the power of the bur kevel who was also a member of the griot caste.
