Possibly Hausa or perhaps Tuareg. Likely first half of the 20th century.
Takouba of the so called southern style with the typical brass plated hilt. Pommel is slightly unusual in that it is leather over iron. Leather is perhaps due to beliefs among the Tuareg regarding the magical properties of iron and the associated dangers of touching it if you are outside the blacksmith classes.
Blade is fairly flexible but inferior steel overall. Ground fullers in the typical triple arrangement with heavily stylized and somewhat crude half moon stamps.
