The Royal House of Semou Njekeh Joof (also known as : Mbin Semou Njike in Serer language or Keur Semou Djiké) was founded in the early 18th century by Maad Semou Njekeh Joof from the Kingdom of Sine, now part of present-day Senegal. It was the third and last royal house founded by the Joof family - (the Joof dynasty of Sine and Saloum) during the Guelowar period, since the reignes of Maad a Sinig Maysa Wali Jaxateh Manneh and Maad a Sinig Mahecor Joof (1350 and 1969 respectively). From the date of its foundation up to the dissolution of Sine in 1969, at least seven kings from this royal house had succeeded to the throne of Sine.
