God's War: A New History of the Crusades

of Jerusalem. Queen Isabella I, daughter and sole surviving heir of King Amalric, married four times between 1183 and 1197, her last three husbands meeting extravagantly unlikely deaths. Conrad of Montferrat was assassinated walking home after dinner (1192). Henry of Champagne walked backwards out of a high window (1197). Aimery was said to have died of a surfeit of fish, white mullet (1205).³⁴ Perhaps perplexed at the workings of providence, Isabella herself followed soon after, still only thirty-three, before other husbands could be put at risk. Her heir, Maria, was a teenager. Maria’s daughter, Isabella II, succeeded in 1212 as a tiny infant. She, in turn, after marrying Frederick II of Germany in 1225, died in 1228 aged sixteen, only a few days after giving birth to her successor, Conrad II of Jerusalem (IV of Germany). Although Conrad reached manhood (dying in 1254), he never visited his eastern kingdom. Nor did his son Conradin, who nominally succeeded aged two as Conrad III of Jerusalem, and was executed in 1268, aged only sixteen, by Charles of Anjou, his rival for the Sicilian throne.³⁵ It says much for the reverence for the form of law, the respect for the blood of the old house of Jerusalem, or merely the convenient habit of an absentee lord that this extraordinary sequence was accepted, continuing a run of unsurpassed dynastic calamities reaching back to the 1170s. Yet the kingdom endured, supplied by its fleets, protected by the walls of its cities and castles and for more than six decades tolerated by neighbours who saw no easy way either to capture Acre or avoid it as an entrepot for commerce.

Following the death of Saladin, holding little more than Acre, Jaffa (lost 1197–1204) and a strip of the coastal plain, Henry of Champagne established a pattern that characterized the new kingdom: peaceful diplomacy with Muslim neighbours where possible; dependence for defence on the military orders; alliance with the Italian maritime communes; and a wary acknowledgement that, without a large royal landed fisc, his powers of independent action and patronage and hence authority over his barons were circumscribed. Henry’s main asset was Acre. After Henry’s death in 1197, the succession was passed to Aimery of Lusignan, brother of Guy and since 1194 ruler and, on receiving a crown from Henry VI of Germany in 1197, king of Cyprus.³⁶ To gain the Jerusalem crown he married Henry’s widow, Isabella I. However, he failed to unite the crowns of Cyprus and Jerusalem.³⁷ Although keen for an alliance, the prospect of a dual monarchy may have proved too much for the Jerusalem barons who had offered Aimery the crown. Only in 1269 was Isabella I’s and Henry of Champagne’s great-grandson, Hugh III of Cyprus, accepted as legitimate king of Jerusalem.

Throughout Aimery’s reign the balance between Frankish – or rather Italian – naval power and Muslim land advantage encouraged compromise. The renewed six-year truce of 1204 restored Jaffa and Ramla to the kingdom, as well as confirming Frankish control of Sidon and improving pilgrim access to Nazareth in Galilee, a business convenience for both sides. The deaths in quick succession in 1205 of Aimery and Isabella I proved the wisdom of the diplomatic approach. The heiress, Maria of Montferrat, was under-age and unmarried. The regent of Jerusalem, Maria’s uncle, Isabella’s half-brother, John of Ibelin (1177–1236), so-called ‘Old Lord of Beirut’, son of Balian of Ibelin and Maria Comnena, could plan what to do when the 1204 treaty expired in 1210. His regency signalled the arrival of a baronial dynasty that came to dominate the politics of Cyprus and Jerusalem for the next century.³⁸ The solution to the succession was unexpected. In a revival of twelfth-century tradition, a husband for Maria had been sought in the west, the choice falling on an energetic, dogged but strangely unsuccessful adventurer from a noble house in Champagne, John of Brienne. Armed with French royal approval, a large subsidy and a small army, he married Maria in 1210, becoming king of Jerusalem, a title he retained after his wife’s death in 1212 as regent for their daughter Isabella II.³⁹ A new six-year treaty was agreed with al-Adil in 1211. On the expiry of the truce, the Fifth Crusade of 1217–21 led to the construction of fortifications at Athlit and Caesarea; the further fragmentation of the Ayyubid empire after the death of al-Adil in 1218; the collapse of John of Brienne’s Armenian ambitions; and another truce.⁴⁰ More ominous, for John of Brienne personally and the kingdom as a whole, the crusade revealed the interest and influence of Frederick II.

The beginning of the Hohenstaufen period in 1225 saw Isabella II married to Frederick II, who became king in her right, immediately depriving John of Brienne of his position. John was left without a kingdom (he later went to Greece in search of another one) and the kingdom without a king, as Isabella and her husband stayed in the west 1225–8. By the time Frederick finally arrived to claim his realm in 1228–9, Isabella was dead and he no longer king. As discussed in the next chapter, his rights as king were challenged at every step by elements of both church and state. Thereafter Frederick attempted to assert by proxy power as regent for his infant son Conrad IV/II. This provoked an extended and bitter civil war, known as the War of the Lombards (1228–43), largely conducted between Frederick’s representative, Richard Filangieri, and local barons led by John of Ibelin, the former regent, and, after his death in 1236, by his son Barisan, and then, from 1239, Philip of Montfort, lord of Toron and Tyre, a nephew of John and relative of the Albigensian crusader Simon of Montfort. The war involved Cyprus, where Frederick claimed overlordship, as well as the mainland.⁴¹ Filangieri, even when recognized as Frederick’s legal representative, was denied authority under the cloak of traditional Jerusalem law. Filangieri was based at Tyre and supported by the Teutonic Knights, Hospitallers, Bohemund V, the new prince of Tripoli-Antioch, the Pisans, and a few Cypriot and Jerusalemite enemies of the Ibelins. His only symbolic trump was his control of Frankish Jerusalem. Most of the rest of the mainland and Cypriot nobility, Acre, the Templars and the Genoese were behind the Ibelins, whose family lands included Beirut, Caesarea and Arsur. In 1231, a commune was established based on the church of St Andrew at Acre to give some corporate cohesion to opposition to Filangieri beyond the legalisms of the High Court; John of Ibelin was its mayor in 1232.⁴²

In May 1232, the imperialists defeated the Ibelins at Casal Imbert but, taking the fight to Cyprus, Filangieri was badly beaten at Agridi the following month; within a year, his supporters had been driven out of Cyprus altogether. The conflict spluttered on acrimoniously until 1242.⁴³ The year before, Simon of Montfort, younger son of the Albigensian crusader, earl of Leicester, and later famous as the leader of the baronial rebellion against Henry III of England in 1258–65, had been offered the post of bailli of Acre by the barons and commune. Married to the sister-in-law of Frederick II, brother-in-law to the king of England and, through his cousin, Philip of Montfort, related to the Ibelins, Simon looked an ideal candidate to reconcile the warring parties. But nothing came of it.⁴⁴ The Lombard War ended the following year, when Conrad IV/II’s majority was declared. Frederick’s claim to the regency was rejected by the High Court in favour of Alice of Cyprus, wife of Hugh I and daughter of Isabella I and Henry of Champagne. She promptly announced the rejection of any authority wielded by Conrad IV/II or his agents. Tyre was seized by the Ibelins and Filangieri arrested. For the next twenty-five years, Jerusalem was an established regency, rather than monarchy.

The main winner from this disorder was the local baronage, especially the Ibelins, who remained the dominant dynastic affinity in both Jerusalem-Acre and Cyprus. Whatever rights of the crown persisted amidst the incessant round of legal and constitutional wrangling were further undermined by the loss to the royal demesne of Tyre. After its capture by the Ibelins in 1242 it quietly slipped into the firm grip of Philip of Montfort, a leader of the Ibelin faction until his assassination in 1270. At the same time, Philip’s cousin John of Ibelin received the exposed county of Jaffa, again with dubious legality. The regencies of Alice of Cyprus (1242–6) and Henry I of Cyprus (1246–53) were almost as ineffectual as the absent Conrad IV/II. From 1253 to 1258 the regency devolved on to rival members of the dominant Ibelin clan while, for selfish rather than prudent reasons, on the death of Conrad IV/II in 1254, the barons accepted as king his two-year-old son Conradin (Conrad III of Jerusalem). However, during his stay in the Holy Land in 1250–54, Louis IX of France exercised effective authority through a sort of parallel administration based on his royal household, military establishment and money. The appointment of Geoffrey of Sergines, commander of the regiment Louis left behind, as marshal, seneschal and, after 1259, lieutenant of the kingdom, finally regent (1261–3, 1264–7), exposed the serial inadequacy and failure of the indigenous politicians.⁴⁵

THE END OF THE KINGDOM OF JERUSALEM

By no means did the Jerusalem baronage hold a monopoly on power or selfishness. From 1256, Genoa and Venice conducted a vicious war, known as the War of St Sabas, that sucked in the Holy Land nobility. The balance of power between the Italian communities had shifted since 1200. In the twelfth century the most committed Italian city had been Pisa, but from the early thirteenth century the Venetians’ interest had grown steadily both in and beyond their headquarters at Tyre.⁴⁶ By the 1250s, the Genoese, long commercial rivals of Venice, were challenging for dominance throughout the eastern Mediterranean from the Black Sea to Egypt. Violence over disputed property in Acre within a year developed into full-scale war involving and dividing the whole political elite. Venice received the support of the Pisans, the Templars, the Teutonic Knights, most of the Ibelins and the Provencals, while the Genoese could depend on the Hospitallers, the increasingly important Catalan merchant community and two leading Ibelins, John of Arsuf and Philip of Montfort, who took the opportunity to try to expel the
