Ibiza together with the islands of Formentera and Minorca were invaded by the Norwegian King Sigurd I of Norway in the spring of 1110 on his crusade to Jerusalem.
The king had previously conquered the cities of Sintra, Lisbon, and Alcácer do Sal and given them over to Christian rulers, in an effort to weaken the Muslim grip on the Iberian peninsula.
The arrival of democracy in the late 1970s led to the Statute of Autonomy of the Balearic Islands.
Today, the island is part of the Balearic Autonomous Community, along with Majorca, Minorca, and Formentera.
Ibiza began establishing its own trading stations along the nearby Balearic island of Majorca, such as Na Guardis, where numerous Balearic mercenaries hired on, no doubt as slingers, to fight for Carthage.
