Lat Dyor Diop (Lat Dior)

Lat Dior Ngoné Latyr Diop (1842–1886), son of Sakhéwère Sokhna Mbaye and the Linguère royal Ngoné Latyr Fall, was a 19th-century Damel (king) of Cayor, a Wolof state that is today in south central Sénégal.

He converted to Islam around 1861, and made common cause with other Wolof and Fulani states to resist French colonialism. Instrumental in his conversion was the Almamy of Rip, Maba Diakhou Bâ. An ally of the Toucouleur empire's El Hadj Umar Tall, Maba convinced Lat-Dior both to convert, and to aid non-Wolof Islamic states of the region against their common foes.

Lat Dior led his troops beside Maba in the battle of Rip on 30 November 1865, at the battle of Pathé Badiane in 1864 and Ngol Ngol in 1865. With Lat Dior, Maba took part in the conquests of the states of Baol and Djolof. They however couldn't conquer the Serer kingdom of Sine and were defeated at The Battle of Fandane-Thiouthioune (18 July 1867) by Maad a Sinig Kumba Ndoffene Famak Joof (King of Sine).

At Kaolack in 1865, they combined forces with soldiers from Waalo, Ndiambour and Ndiander to face the French fortifications of governor Émile Pinet-Laprade but were repulsed.
