of Muawiyah I. They conquered the capital Salamis - Constantia after a brief siege, but drafted a treaty with the local rulers. In the course of this expedition a relative of Muhammad, Umm-Haram, fell from her mule near the Salt Lake at Larnaca and was killed. She was buried at that spot and the Hala Sultan Tekke was built there in Ottoman times. Under Abu'l-Awar, the Arabs returned in 650 and installed a garrison of 12,000 on part of the island, where they remained until 680. In 688, the emperor Justinian II and the caliph Abd al-Malik reached an unprecedented agreement. The Arabs evacuated the island, and for the next 300 years, Cyprus was ruled jointly by both the Caliphate and the Byzantines as a condominium, despite the nearly constant warfare between the two parties on the mainland. The collected taxes were divided among the Arabs and the emperor. Under Basil I the Macedonian (r. 867–886) Byzantine troops recaptured Cyprus, which was established as a theme, but after seven years the island reverted to the previous status quo. Once again, in 911, the Cypriots helped a Byzantine fleet under admiral Himerios, and in retaliation the Arabs under Damian of Tarsus ravaged the island for four months and carried off many captives. The isolation of Cyprus from the rest of the Greek-speaking world assisted the formation of a separate Cypriot dialect. This period of Arab influence lasted until the 10th century. Byzantine reconquest In the year 965 or slightly earlier, the Byzantines reconquered the island and installed theme. The general Niketas Chalkoutzes led the reconquest, of which no details are known, and was probably the first governor of Cyprus after that. A rebellion by governor Theophilos Erotikos in 1042, and another in 1092 by Rhapsomates, failed as they were quickly subdued by imperial forces. In 1185, the last Byzantine governor of Cyprus, Isaac Komnenos, from a minor line of the Komnenos imperial house, rose in rebellion and attempted to seize the throne. His attempted coup was unsuccessful, but Komnenos was able to retain control of the island. Byzantine actions against Komnenos failed because he enjoyed the support of William II of Sicily. The emperor had agreed with the sultan of Egypt to close Cypriot harbours to the Crusaders. Crusades–Lusignan period 1095–1489 During the Siege of Antioch, a battle of the First Crusade, the Crusader army received supplies from Byzantine-controlled Cyprus. In
