In 1114, the Count of Barcelona, Ramon Berenguer, gathered a group of nobles from Pisa and other Provençal and Italian cities, including the Viscount of Narbonne and the Count of Montpellier.
This group of nobles launched a retaliatory expedition against the island to combat the pirate raids being organized on Majorca.
The objective of this mission was to wrest Majorca from Muslim control, establish a Christian government, and thereby prevent any further attacks on shipping by Christian merchants.

After an eight-month siege, Berenguer had to return home because an Almoravid offensive was threatening Barcelona.
He left the Genoese in charge, but they ultimately gave up on the siege and fled with the captured spoils.
Although the siege failed, it laid the foundation for future Catalan naval power and strengthened strategic alliances among Christian kingdoms around the Mediterranean.

In Pisa there are still some remains that were moved from Mayurqa.
There is also an account of the expedition in a Pisan document called Liber maiolichinus, in which Ramon Berenguer III is referred to by the appellate "Dux Catalensis" or "Catalanensis" and "catalanicus heros", while his subjects are called "Christicolas Catalanensis".
This is considered the oldest documented reference to Catalonia that has been identified within the domains of the Count of Barcelona.

The siege of Majorca prompted the Almoravid caliph to send a relative of his to take over the local government and rebuild the province.
The new wāli led to a dynasty, the Banû Gâniya, which, from its capital at Madina Mayurqa, tried to reconquer the Almoravid empire.
King Alfonso II, using Sicilian ships, organised a new expedition and again attempted to conquer the island, but was unsuccessful.
