Thilas
Thilas was an ancient title of nobility used in the Serer pre-colonial Kingdoms of Sine, Saloum and previously the Kingdom of Baol, which are all now part of modern-day Senegal. The Thilas was the second in the order of succession to the throne after the Buumi who was the heir apparent.
Only members of the royal family could hold this title. When a Maad a Sinig dies without a Buumi, the Thilas could ascend the throne at the discretion of the Great Jaraff and his Noble Council of Electors responsible for electing the kings from the royal family. In the history of Sine to its 20th century history, such an incident is only known to have occurred once, at the succession of Maad a Sinig Kumba Ndoffene Fa Ndeb Joof whose predecessor died without a Buumi.
Before the abolition of the Serer monarchies in 1969, the Thilas always took residence at Djilas in the Sine.
