Lord Edward's crusade

Following the Mamluk victory over the Mongols in 1260 at the Battle of Ain Jalut by Qutuz and his general Baibars, Qutuz was assassinated, leaving Baibars to claim the sultanate for himself. As Sultan, Baibars proceeded to attack the Christian crusaders at Arsuf, Atlit, Haifa, Safad, Jaffa, Ascalon, and Caesarea. As the Crusader fortress cities fell one by one, the Christians sought help from Europe, but assistance was slow in coming.

In 1268, Baibars captured Antioch, thereby destroying the last remnant of the Principality of Antioch, securing the Mamluk northern front and threatening the small Crusader County of Tripoli. With royal and papal approval, Edward "took the cross" on 24 June 1268.[4] Louis IX of France organized a large crusader army with the intent of attacking Egypt, but diverted it instead to Tunis. Louis himself died there in 1270. He had loaned Edward 70,000 livres tournois for his crusade.[5]

Edward and his brother Edmund prepared an expedition to join Louis at Tunis, but it was delayed several times in the summer of 1270 because their father, King Henry III of England, could not make up his mind whether to join it or not. On the advice of his councilors, he opted to stay in England and the crusaders embarked at Dover on 20 August.[6]

Edward traveled slowly through France, arriving in Aigues-Mortes, the same port from which Louis had embarked, in late September (a month later than expected).[5] He went from there to Sardinia, where he waited a month before crossing to Tunis, where he arrived on 10 November, too late for the fighting.[6] In fact, the Treaty of Tunis that ended the crusade had been signed on 30 October. Although Edward had played no role in its negotiation, the treaty obligated its signatories—Philip III of France, Charles I of Sicily and Theobald II of Navarre—to prevent Edward from attacking Tunis. Edward was also excluded from receiving a portion of the indemnity paid to the crusaders for leaving.[7]

On 18 November, Charles granted Edward a safe-conduct allowing him to stay in Sicily while contemplating his next steps.[6] Although the other crusaders decided each to return home, Edward opted to continue on his way to the Holy Land to assist Bohemund VI, Prince of Antioch and Count of Tripoli, against the Mamluk threat to the remnant of the Kingdom of Jerusalem. On 9 May 1271 Edward finally arrived at Acre[8] with a fleet of eight sailing vessels and thirty galleys.[9] He brought a small but not insignificant contingent of no more than 1,000 men, including 225 knights.[10][11]

Edward arrived at Acre while it was still under siege. His arrival caused Baibars to change his plans and turn away from Acre.[8] In the meantime, Edward discovered that the Venetians had a flourishing trade with the Mamluks, providing the latter with timber and metal needed for armaments. In addition, they controlled the slave-trade along with the Genoese, in which they carried Turkish and Tartar slaves from the Black Sea ports to Egypt. However, he could not prevent such businesses, as they had licenses from the High Court at Acre.[12]

Mongol raids

As soon as Edward arrived in Acre, he made some attempts to form a Franco-Mongol alliance, sending an embassy to the Mongol ruler of Persia Abagha, an enemy of the Muslims. The embassy was led by Reginald Rossel, Godefroi of Waus and John of Parker, and its mission was to obtain military support from the Mongols.[19] In an answer dated 4 September 1271, Abagha agreed on cooperation and asked on what date the concerted attack on the Mamluks should take place.[20]

At the end of October 1271, a Mongol army arrived in Syria. However Abagha, occupied by other conflicts in Turkestan could only send 10,000 horsemen under general Samagar, a force made up of the occupation army in Seljuk Anatolia and auxiliary Seljukid troops. Despite the relatively small force, their arrival still triggered an exodus of Muslim populations (who remembered the previous campaigns of Kitbuqa) as far south as Cairo. The Mongols defeated the Turcoman troops that protected Aleppo, and raided southwards, sending the other garrisons fleeing for Hama, and devastating the lands down to Apamea. But the Mongols did not stay, and when the Mamluk leader Baibars mounted a counter-offensive from Egypt on 12 November the Mongols had already retreated beyond the Euphrates, laden with booty.[21][22]

Edward had been accompanied by Theobald Visconti, who became Pope Gregory X in 1271.[27] Gregory called for a new crusade at the Council of Lyons in 1274, but nothing came of this. Meanwhile, new fissures arose within the Christian states when Charles of Anjou took advantage of a dispute between Hugh III, the Knights Templar, and the Venetians to bring the remaining Christian state under his control. Having bought Mary of Antioch's claims to the Kingdom of Jerusalem, he attacked Hugh III, causing a civil war within the rump kingdom. In 1277, Roger of San Severino captured Acre for Charles.

Although the crusaders' internecine war was debilitating, it offered the possibility of unified control of the crusade under Charles. However, this hope was dashed when Venice suggested a crusade be called not against the Mamluks but against Constantinople, where Michael VIII had recently re-established the Byzantine Empire and driven out the Venetians. Pope Gregory would not have supported such an attack, but in 1281 Pope Martin IV assented to it; the ensuing fiasco helped lead to the Sicilian Vespers on 31 March 1282, instigated by Michael VIII, and Charles was forced to return home. This was the last crusader expedition launched against the Byzantines in Europe or the Muslims in the Holy Land.

The remaining nine years saw an increase in demands from the Mamluks, including tribute, as well as increased persecution of pilgrims, all in contravention of the truce. In 1289, Sultan Qalawun gathered a large army and invested the remnants of the county of Tripoli. He ultimately laid siege to the capital and took it after a bloody assault. The attack on Tripoli however was particularly devastating to the Mamluks as the Christian resistance reached fanatical proportions and Qalawun lost his eldest and most able son in the campaign. He waited another two years to regather his strength.

In 1275, Abaqa sent a messenger to Edward with a letter. Abaqa requested that Edward mobilize for another Crusade, saying he could offer more help this time. Edward wrote back the same year, thanking Abaqa for his help in the Ninth Crusade while also noting his affection for Christianity. He said he did not know when there would be another Crusade, but was eager to get back to the Holy Land, and would inform Abaqa if the Pope declared another. The letter was almost certainly a formality, as Edward made no preparations for another Crusade. In 1276, another envoy was sent to Edward with the same message, with an additional message of apology for not effectively intervening in 1271.[28]

In 1291, a group of pilgrims from Acre came under attack and in retaliation killed nineteen Muslim merchants in a Syrian caravan. Qalawun demanded they pay an extraordinary amount in compensation. When no reply came, the Sultan used it as a pretext to besiege Acre and finish off the last independent Crusader state occupying the Holy Land. Qalawun died during the siege, leaving Khalil, the sole surviving member of his family, as Mamluk Sultan. With Acre seized, the Crusader States other than Cyprus ceased to exist. The center of power of the Crusaders was moved northwards to Tortosa and eventually offshore to Cyprus. In 1299, a Mongol army led by Ghazan Khan led a series of successful raids against the Mamluks in an area northeast of Homs to as far south as Gaza. He finally withdrew from Syria in 1300. The Mongols and Armenian Kingdom of Cilicia led another campaign to recapture Syria, but were soon defeated by the Mamluks at the Battle of Shaqhab in 1303. The last remaining foothold on the Holy Land, Ruad Island, was lost by 1303. The period of the Crusades to the Holy Land was over, 208 years after the beginning of the First Crusade.
