Barbary Crusade
The Barbary Crusade, also called the Mahdia Crusade, was a Franco-Genoese military expedition in 1390 that led to the siege of Mahdia, then a stronghold of the Barbary pirates in Hafsidi Ifriqiya (geographically corresponding to modern Tunisia). "Froissart's Chronicles" is the chief account of what was one of the last crusades.
