A very engaging non-fiction about the colonisation by the French of what is now #Senegal, #Guinea and #Mali, and its ramifications in modern-day France and Senegal, centered around the mythical sabre of El Hadj Oumar Tall, looted along with his treasure and library in 1890, at the sack of Ségou by the French colonial army.
The sabre (picture from https://chroniques.sn) was “lent back“ by France to the musée des civilisations noires in Dakar
