The 1390 Barbary Crusade: A Chivalric Adventure That Failed to Learn Its Lessons
When French knights sought glory during a lull in the Hundred Years' War, they launched a crusade against North African pirates. This expedition to Mahdia, Tunisia, was less a holy mission than a quest for prestige, ultimately serving as a disastrous rehearsal for the catastrophic failure at Nicopolis years later.
In 1390, Genoese ambassadors approached the French King Charles VI with a proposal to attack Mahdia, a stronghold of Barbary pirates. Genoa offered 12,000 archers and 8,000 foot soldiers, while France provided 1,500 knights led by Louis II, Duke of Bourbon. The expedition was framed as a crusade, granting participants debt relief, legal immunity, and papal indulgence from Pope Boniface IX. For the knights, it was an opportunity for honor and payment during a quiet period in the Hundred Years' War.
The conflict quickly stalled. Hafsid Sultan Abu al-Abbas Ahmad II arrived with a massive relief force, forcing the crusaders to fortify their camp. When the Berbers questioned the invasion, the French cited the crucifixion of Jesus, to which the Berbers retorted that the Jews—not they—were responsible. As the siege dragged on, the crusaders suffered from logistical failures and the inability to overcome the local forces. By mid-October, a treaty was signed, resulting in a ten-year armistice.
The expedition was a strategic failure for the French, who lacked clear goals beyond the pursuit of glory. They suffered 274 losses among their knights and squires due to combat and disease. Crucially, the campaign revealed deep-seated issues: unfamiliarity with the environment, poor siege equipment, and internal discord. These same mistakes were repeated six years later on a much larger scale at the Crusade of Nicopolis in 1396. While the Barbary Crusade is often viewed as a typical small-scale, localized expedition, it remains a cautionary tale of chivalric hubris.
The political landscape of the era was complex, with the crusade endorsed by the Roman Pope Boniface IX, contrasting with later expeditions in 1398 and 1399 supported by the Avignon Papacy. Unlike the massive, organized effort at Nicopolis, the Mahdia expedition lacked the ambition of conquest, yet its failure provided a grim preview of the decline of the crusading movement.
