Maad a Sinig Mahecor Joof

Maad a Sinig Mahecor Joof (English spelling in the Gambia; variations : Maad a Sinig Mahécor Diouf - French in Senegal; Maad Siin or Mad a Sinig Mahekor Juuf, also Maye Koor Juuf - in Serer-Sine language) was the last king to rule the Serer Kingdom of Sine now part of independent Senegal. Maad a Sinig means king of Sine in Serer language. He reigned from 1924 until his death in 1969 (3 August 1969, he died at Diakhao).

On his maternal line, he is a member of the Guelowar dynasty.

By 1969, Maad Mahecor Joof although retired, was the only ruler in Senegal who possessed real power. The Serer kingdoms such as Sine and Saloum were the only pre-colonial kingdoms to survive up to 1969 (six years after Senegal gained independent from France). The Maad a Sinig (King of Sine) was very committed in the preservation of Serer culture and tradition. During his reign, the Kingdom of Sine was economically prosperous.
