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.



During the lulls of the Hundred Years War knights looked for opportunities for glory and honor. [1] As Genoese ambassadors approached the French king Charles VI to subscribe to a crusade, they eagerly supported the plan to fight Muslim pirates from North Africa. These pirates had their main base at Mahdia on the Barbary coast. Genoa was ready to supply ships, supplies, 12,000 archers and 8,000 foot soldiers, if France would provide the knights. [1] The proposal by the doge Antoniotto Adorno was presented as a crusade. As such it would give prestige to its participants, a moratorium on their debts, immunity from lawsuits, and papal indulgence. [2] The French force also included some English participants and consisted of 1,500 knights under the leadership of Louis II, Duke of Bourbon.

Siege of Mahdia

A relief army reportedly 40,000 men strong was brought up by Hafsid Sultan Abu al-Abbas Ahmad II supported by the kings of Bejaia and Tlemcen who camped nearby, avoided pitched battle, but started to harass the crusaders. The Crusaders had to build a wall around their camp and fortify it. The Berbers sent out a negotiating party asking why the French would attack them, they had only troubled the Genoese, a natural affair among neighbors. In answer they were told that they were unbelievers who had "crucified and put to death the son of God called Jesus Christ." The Berbers laughed saying it was the Jews not they who had done that. [2] Negotiations broke off.

In a subsequent encounter with the large relief army the Crusaders killed many but eventually had to retreat exhausted and tired. The duration of the siege not only frustrated them, but their logistical systems started to weaken. When a final assault on the city was repelled they were ready to settle for a treaty. On the opposing side the Berbers realized that they could not overcome the heavier armed invaders. Both sides looked for a way to end the hostilities.

Lifting the siege

The siege was lifted with the conclusion of a treaty negotiated through the Genoese party. The treaty stipulated a ten-year armistice. By mid-October the Crusaders had returned to Genoa. Losses due to the fighting and disease amounted to 274 knights and squires. [2]


Both sides celebrated victory. The Berbers had repelled the invaders, and the Genoese could conduct trade with less interference. The French knights had no tangible goals but had participated for action and glory. They failed to learn any lessons from a "chivalric adventure with religious overlay". [2] Their mistakes of unfamiliarity with the environment, lack of heavy siege equipment, underestimation of the enemy, and internal quarrels were repeated six years later on a grander scale in their fatal last crusade, at Nicopolis.

Genoa, Italy, has historically been one of the most important ports on the Mediterranean.

The Venetian–Genoese Wars were a series of struggles between the Republic of Genoa and the Republic of Venice, at times allied with other powers, for dominance in the Mediterranean Sea between 1256 and 1381. There were four bouts of open warfare, in which the fighting between the two republics took place largely at sea. Even during periods of peace, incidents of piracy and other minor outbreaks of violence between the two trading communities were commonplace.

<span class="mw-page-title-main">Fall of Tripoli (1289)</span>

The Fall of Tripoli was the capture and destruction of the Crusader state, the County of Tripoli, by the Muslim Mamluks. The battle occurred in 1289 and was an important event in the Crusades, as it marked the capture of one of the few remaining major possessions of the Crusaders. The event is represented in a rare surviving illustration from a now fragmentary manuscript known as the 'Cocharelli Codex', thought to have been created in Genoa in the 1330s. The image shows the countess Lucia, Countess of Tripoli and Bartholomew, Bishop of Tortosa sitting in state in the centre of the fortified city, and Qalawun's assault in 1289, with his army depicted massacring the inhabitants fleeing to boats in the harbour and to the nearby island of St Thomas.

Abu 'Amr 'Uthman, regnal title al-Mutawakkil 'ala Allah was the Hafsid ruler of Ifriqiya, or modern Tunisia, eastern Algeria and western Libya, who reigned between 1435 and 1488. A Flemish merchant who arrived at his court in Tunis in 1470 described him as tall, thoughtful, just, and pious, and called him the "greatest, most powerful, and richest of all Moorish princes." His reign was a period of relative stability and of military and diplomatic successes for the Hafsid kingdom. Uthman would prove to be the last effective Hafsid ruler, and the dynasty entered a long decline after his death until the Ottomans captured Tunis in 1574. Modern historian Jamil Abun-Nasr has called him the "last drop of Hafsid glory."

Mahdia was abandoned by Spain three years later, and all its fortifications were demolished to avoid a re-occupation of the city by the Ottomans.
