In the pre-colonial era, Moors from Mauritania who came to settle in the Serer kingdoms such as the Kingdom of Sine, etc., were ill-treated by their Serer masters. If a Moor dies in a Serer kingdom, his body was dragged out of the country and left for the vultures to feast on if there is no family or friend to claim the body and bury it elsewhere. They were also never accompanied by grave goods. No matter how long a Mauritanian Moor has lived in the area as a migrant, he could never achieve high status within the Serer aristocracy. The best position he could ever wish for within Serer high society was to work as a "Bissit" (Bissik). Apart from spying for the Serer Kings, the "Bissit's" main job was to be a clown – for the sole entertainment of the Serer King, the Serer aristocracy and the common people. He was expected to dance in ceremonies before the king and liven up the king's mood and the king's subjects. This position was always given to the Moors. It was a humiliating job and not a title of honour. According to some, the history of this position goes back to an early Moor in Serer country who had a child by his own daughter.
