Kumba Ndoffene Fa Ndeb Joof

Maad a Sinig Kumba Ndoffene Fa Ndeb Joof (Serer: Maad a Sinig Kumba Ndoofeen fa Ndeb Juuf), also known as Kumba Ndoffene Joof II or Bour Sine Coumba Ndoffène Fandepp Diouf, was a King of Sine (in present-day Senegal). Maad a Sinig translates as "King of Sine", Maad meaning king in the Serer language or one who bears witness. The surname Joof is the English spelling in the Gambia. Diouf is the French spelling in Senegal (see: Joof family).

There is no consensus regarding the exact date that Maad Kumba Ndoffene Fa Ndeb succeeded to the throne. According to some, he reigned from 1898 to 1924, which correlates with the written sources available at the time. Other historians propose that, he reigned from 1897 or 1898 to 1923. This version agrees pretty much with the oral tradition of the Serer people. According to Serer tradition, the king was very ill before his death and ruled for 27 winters (27 years) before his successor - Maad a Sinig Mahecor Joof succeeded to the throne. When the King died, there was a period of mourning and it took a little while to prepare for the Coronation ceremony of Maad a Sinig Mahecor Joof according to Serer custom and tradition. Maad Mahecor Joof ascended to the throne in 1924, more precisely, according to some, on 28 January 1924. Regarding the year Maad a Sinig Kumba Ndoffene Fa Ndeb Joof died, there is consensus that it was in 1923, more specifically on 21 December 1923 at Diakhao.

Maad a Sinig Kumba Ndoffene Fa Ndeb Joof should not be confused with his great-uncle Maad a Sinig Kumba Ndoffene Famak Joof, also known as Coumba Ndoffène I, who reigned from 1853 to August 1871. The prefix Famak (or Fa mak) means "the elder" in the Serer language. Fa Ndeb (also :Fandepp, Fa ndepp or Fandeb) means "the young" in Serer. These prefixes were later additions (during and after the reigne of Maad a Sinig Kumba Ndoffene Fa Ndeb) to differentiate the two Kings of Sine who shared the same name and surname.
