Jolof Empire
Around early 1550, both Sine and its sister Serer Kingdom (the Kingdom of Saloum) overthrew the Jolof and became independent Kingdoms. Serer oral tradition says that the Kingdom of Sine never paid tribute to Ndiadiane Ndiaye nor any of his descendants and that the Jolof Empire never subjugated the Kingdom of Sine and Ndiadiane Ndiaye himself received his name from the mouth of Maysa Waly. The historian Sylviane Diouf states that "Each vassal kingdom—Walo, Takrur, Kayor, Baol, Sine, Salum, Wuli, and Niani—recognized the hegemony of Jolof and paid tribute."
