Damel was the title of the ruler (or king) of the Wolof kingdom of Cayor in what is now northwest Senegal, West Africa.
The most well-known damel is probably Lat Dior Diop (1842–1886) who died in battle during the final French drive to capture his territory, which was one of the strongest areas of resistance. Lat Dior is a Senegalese national hero.
The 30th and last Damel of Cayor, Samba Laobé Fall, was killed by the leader of a French delegation, Captain Spitzer, at Tivaouane, Senegal.
