Siege of Ragusa (866–868) (Mediterranean)

The siege of Ragusa (modern Dubrovnik in Croatia) by the Aghlabids of Ifriqiya lasted for fifteen months, beginning in 866 until the lifting of the siege at the approach of a Byzantine fleet in 868. The failure of the siege and the re-appearance of the Byzantines in the region of Dalmatia signalled the beginning of new aggressive western policy by the new Byzantine emperor, Basil I. Its immediate effects were the re-establishment of Byzantine authority there in the form of the Theme of Dalmatia, and the beginning of the Christianization of the Slavs of the western Balkans, but within a few years it led to renewed Byzantine involvement and presence in southern Italy as well.
