Treaty and preparations

In 1085 Pope Gregory VII had granted suzerainty over the Balearics to Pisa.[2] In September 1113 a Pisan fleet making an expedition to Majorca was put off course by a storm and ended up near Blanes on the coast of Catalonia, which they initially mistook for the Balearics.[3] The Pisans met with the Count of Barcelona in the port of Sant Feliu de Guíxols, where on 7 September they signed a treaty causa corroborandae societatis et amicitiae ("for the cause of social cooperation and friendship"). Specifically the Pisans were exempted from the usagium and the jus naufragii in all the territories, present and future, of the Count of Barcelona, though Arles and Saint-Gilles, in the recently acquired March of Provence, were singled out for special mention (three times).[4]

The only surviving copy of the treaty between Pisa and Barcelona is found interpolated in a charter of James I granted to Pisa in 1233. It affirms that the meeting was unplanned and apparently arranged by God.[5] Some scholars have expressed doubt about the lack of preparation, citing the Catalans' rapid response to the presence of the Pisans as evidence of some previous contact.[6] The attribution of the meeting to Providence alone may have been concocted to add an "aura of sacredness" to the alliance and the crusade.[4]

The treaty, or what survives of it, does not refer to military cooperation or a venture against Majorca; perhaps that agreement was oral, or perhaps its record has been lost, but a Crusade was planned for 1114. The chief goal was the freeing of Christian captives and the suppression of Muslim piracy.[7] Most of the Pisan fleet returned to Pisa, but some ships damaged by the storm remained to be repaired and some men remained behind to construct siege engines.[8] In the spring of 1114 a new fleet of eighty ships arrived from Pisa, following the French coast, briefly staying at Marseille.[9]

The fleet brought with it Cardinal Bosone, an envoy from Paschal II, who vigorously supported the expedition, authorising it in a bull as early as 1113.[2] Paschal had also granted the Pisans the Romana signa, sedis apostolicae vexillum ("Roman standard, the flag of the apostolic see"),[10] and his appeals for the expedition had borne fruit. Besides the 300 ships of the Pisan contingent, there were 120 Catalan and Occitan vessels (plus a large army), contingents from the Italian cities of Florence, Lucca, Pistoia, Rome, Siena, and Volterra, and from Sardinia and Corsica under Saltaro, the son of Constantine I of Logudoro. Among the Catalan princes there were Ramon Berenguer, Hug II of Empúries, and Ramon Folc II of Cardona.[11] The most important lords of Occitania participated, with the exception of the Count of Toulouse, Alfonso Jordan: William V of Montpellier, with twenty ships; Aimeric II of Narbonne, with twenty ships; and Raymond I of Baux, with seven ships.[11] Bernard Ato IV, the chief of the Trencavel family, also participated.[12] Ramon Berenguer and his wife, Douce, borrowed 100 morabatins from the Ramon Guillem, the Bishop of Barcelona, to finance the expedition
