[1500]

With the outbreak of hostilities in La Alpujarras the Barbarossa brothers see their chance. In the early sailing season the corsairs depart from the Tunisian Caliphate and venture first to the island of Djerba which had been going through a strange phase of quasi-independence since around the 1480s. The arrival of the Barbarossa brothers heralds the return of (at least tentative) Caliphal authority on the island and a new base for nefarious pirate stuff or whatever it is the Barbarossa brothers do.

Following the seizure of the island of Djerba, the Barbarossa brothers proceed to launch incursions against the southern coast of Spain landing quickly upon the shores and darting away to safe havens across the ocean in Africa. Overall it creates a huge headache for an already overloaded Spanish military situation and causes yet more strife in the area. Luckily for Barbarossa though, they're able to contribute significantly to the effort of al-Ganī and Morocco in ferrying civilians and refugees from Granada to, once more, safe ports in Africa.

All in all, the Barbarossa brothers come out of this scenario a little richer, a little more famous, and infinitely more smug.
