Emirate of Crete The Emirate of Crete was a Muslim state that existed on the Mediterranean island of Crete from the late 820s to the Byzantine reconquest of the island in 961 . Although the emirate recognized the suzerainty of the Abbasid Caliphate and maintained close ties with Tulunid Egypt , it was " de facto " independent . A group of Andalusian exiles conquered Crete in ca . 824 or in 827 / 828 , quickly establishing an independent state . Numerous attempts by the Byzantine Empire to recover the island failed disastrously , and for the approximately 135 years of its existence , the emirate ( called " Iqritish " or " Iqritiya " by the Arabs ) was one of the major foes of Byzantium . Crete commanded the sea lanes of the Eastern Mediterranean and functioned as a forward base and safe haven for corsair fleets from the Muslim world that ravaged the Byzantine - controlled shores of the Aegean Sea . The emirate ' s internal history is less well - known , but all accounts point to considerable prosperity deriving not only from piracy but also from extensive trade and agriculture . The emirate was brought to an end by Nikephoros Phokas , who launched a huge campaign against it in 960 – 961 . History . Crete had been the target of Muslim attacks since the first wave of the Muslim conquests in the mid - 7th century . It had suffered a first raid in 654 and again in 674 / 675 , and parts of the island were temporarily occupied during the reign of the Umayyad Caliph al - Walid I ( r . 705 – 715 ) . Nevertheless , the island was never conquered and despite occasional raids in the 8th century it remained securely in Byzantine hands ; Crete was too far from the Arab naval bases in the Levant for an effective expedition against it to be undertaken . Conquest of Crete . At some point in the second half of the reign of Byzantine Emperor Michael II ( r . 820 – 829 ) , a group of Andalusian exiles landed on Crete and began its conquest . These exiles had a long history of wanderings behind them . They were the survivors of a failed revolt against the emir Al - Hakam I of Córdoba in 818 . In the aftermath of its suppression , the citizens of the Cordovan suburb of al - Rabad were exiled " en masse " . Some settled in Fez in Morocco , but others , numbering over 10 , 000 , took to piracy , probably joined by other Andalusians . Some of the latter group , under the leadership of Umar ibn Hafs ibn Shuayb ibn Isa al Balluti , commonly known as Abu Hafs , landed in Alexandria and took control of the city until 827 , when they were besieged and expelled by the Abbasid general Abdullah ibn Tahir al - Khurasani . The exact chronology of their landing in Crete is uncertain . Following the Muslim sources , it is usually dated to 827 or 828 , after the Andalusians ' expulsion from Alexandria . Byzantine sources however seem to contradict this , placing their landing soon after the suppression of the large revolt of Thomas the Slav ( 821 – 823 ) . Further considerations regarding the number and chronology of the Byzantine campaigns launched against the invaders and prosopographical questions of the Byzantine generals that headed them have led other scholars like Vassilios Christides and Christos Makrypoulias to propose an earlier date , ca . 824 . Under the terms of their agreement with Ibn Tahir , the Andalusians and their families left Alexandria in 40 ships . Historian Warren Treadgold estimates them at some 12 , 000 people , of whom about 3 , 000 would be fighting men . According to Byzantine historians , the Andalusians were already familiar with Crete , having raided it in the past . They also claim that the Muslim landing was initially intended as a raid , and was transformed into a bid for conquest when Abu Hafs himself set fire to their ships . However , as the Andalusian exiles had brought their families along , this is probably later invention . The Andalusians ' landing - place is also unknown ; some scholars think that it was at the north coast , at Suda Bay or near where their main city and fortress Chandax ( , , " Castle of the Moat " , modern Heraklion ) was later built , but others think that they most likely landed on the south coast of the island and then moved to the more densely populated interior and the northern coast . As soon as Emperor Michael II learned of the Arab landing , and before the Andalusians had secured their control over the entire island , he reacted and sent successive expeditions to recover the island . Losses suffered during the revolt of Thomas the Slav hampered Byzantium ' s ability to respond , however , and if the landing occurred in 827 / 828 , the diversion of ships and men to counter the gradual conquest of Sicily by the Tunisian Aghlabids also interfered . The first expedition , under Photeinos , " strategos " of the Anatolic Theme , and Damian , Count of the Stable , was defeated in open battle , where Damian was killed . The next expedition was sent a year later and comprised 70 ships under the " strategos " of the Cibyrrhaeots Krateros . It was initially victorious , but the overconfident Byzantines were then routed in a night attack . Krateros managed to flee to Kos , but there he was captured by the Arabs and crucified . Makrypoulias suggests that these campaigns must have taken place before the Andalusians completed their construction of Chandax , where they transferred the capital from the inland site of Gortyn . The " pirate " emirate . Abu Hafs repulsed the early Byzantine attacks and slowly consolidated control of the entire island . He recognized the suzerainty of the Abbasid Caliphate , but he ruled as a " de facto " independent prince . The conquest of the island was of major importance as it transformed the naval balance of power in the Eastern Mediterranean and opened the hitherto secure Aegean Sea littoral to frequent and devastating raids . The Andalusians also occupied several of the Cyclades during these early years , but Michael II organized another large - scale expedition , recruiting an entire new marine corps , the " Tessarakontarioi " , and building new ships . Under the admiral Ooryphas , this fleet managed to evict the Arabs from the Aegean islands but failed to retake Crete . Michael II ' s successor Theophilos ( r . 829 – 842 ) sent an embassy to Abd ar - Rahman II of Córdoba proposing a joint action against the Andalusian exiles , but beyond Abd ar - Rahman giving his assent to any Byzantine action against Crete , this came to nothing . In October 829 , the Cretans destroyed an imperial fleet off Thasos , undoing much of the work of Ooryphas and opening the Aegean and its coasts to pillage . Later they attacked Euboea ( ca . 835 – 840 ) , Lesbos ( 837 ) , and the coasts of the Thracesian Theme , where they destroyed the monastic centre of Mount Latros . They were heavily defeated , however , by the local " strategos " , Constantine Kontomytes . After the death of Theophilos in 842 , new measures to confront the Cretan threat were undertaken by the new Byzantine regime : in 843 a new maritime theme , that of the Aegean Sea , was established to better deal with the Saracen raids , and another expedition to recover Crete was launched under the personal leadership of the powerful " logothetes " and regent Theoktistos . Although it succeeded in occupying much of the island , Theoktistos had to abandon the army due to political intrigues in Constantinople , and the troops left behind were slaughtered by the Arabs . In an effort to weaken the Saracens in 853 , several Byzantine fleets engaged in coordinated operations in the Eastern Mediterranean , attacking the Egyptian naval base of Damietta and capturing weapons intended for Crete . Despite some Byzantine successes against the Arabs in the following years , the Cretans resumed their raids in the early 860s , attacking the Peloponnese , the Cyclades , and Athos . In 866 , the Byzantine " Caesar " Bardas assembled another large - scale expeditionary force to subdue Crete , but his murder by Basil the Macedonian only two weeks after the fleet set sail from the capital spelled the end of the undertaking . In the early 870s , the Cretan raids reached a new intensity : their fleets , often commanded by Byzantine renegades , ranged the Aegean and further afield , reaching the Dalmatian coasts . On one occasion a Cretan fleet even penetrated into the Marmara Sea and unsuccessfully attacked Proconnesos ; the first time since the Second Arab Siege of Constantinople in 717 – 718 that a Muslim fleet had come so close to the Byzantine capital . In 873 and again in 874 however , they also suffered two successive heavy defeats at the hands of the new Byzantine admiral , Niketas Ooryphas . After the latter battle in particular , Ooryphas took many prisoners , whom he tortured extensively in revenge for their raids . At about the same time , the Muslim fleet of Tarsus was destroyed off Chalcis . These Byzantine victories apparently led to a temporary truce , and it appears that the Cretan emir Saipes ( Shuayb I ibn Umar ) was obliged to pay tribute to Byzantium for about a decade . Raids resumed soon after , in which the Cretans were joined by North African and Syrian fleets . The Peloponnese in particular suffered considerably from their raids , but also Euboea and the Cyclades : the island of Patmos came under Cretan control ; Naxos , probably along with the neighbouring islands of Paros and Ios , was forced to pay them tribute ; and Elafonisos and Cythera off the southern coast of the Peloponnese were also occupied . As the Muslim presence left generally few material or literary traces , the list of islands at one time controlled or occupied by them could well be longer . Nevertheless , the impact of this new wave of Arab raids was felt across the Aegean , where some islands were deserted altogether , and elsewhere coastal sites were abandoned for better protected inland locations . Athens may have been occupied in ca . 896 – 902 , and in 904 , a Syrian fleet led by Leo of Tripoli sacked the Byzantine Empire ' s second city , Thessalonica . The Saracens of Crete co - operated closely with their Syrian counterparts , who often used Crete as a base or a stop - over , as during Leo of Tripoli ' s fleet return from Thessalonica , when many of the over 20 , 000 Thessalonian captives were sold or gifted as slaves in Crete . Likewise , the Cretan emirate received strong support from the Tulunid governors of Egypt ( 868 – 905 ) , but their Ikhshidid successors neglected the aid to Crete . In 911 , another large - scale expedition of well over 100 ships was launched against Crete , headed by the admiral Himerios , but it was forced to leave the island after a few months . On its return journey , Himerios ' fleet was destroyed in battle off Chios by the Syrian fleet . Byzantine reconquest . Cretan piracy reached another high in the 930s and 940s , devastating southern Greece , Athos , and the western coasts of Asia Minor . As a result , Emperor Constantine VII ( r . 913 – 959 ) sent another expedition in 949 . This too was routed in a surprise attack , a defeat which Byzantine chroniclers ascribe to the incompetence and inexperience of its leader , the eunuch chamberlain Constantine Gongyles . Constantine VII did not give up , and during the last years of his reign he began preparing another expedition . It would be carried out under his successor , Romanos II ( r . 959 – 963 ) , who entrusted its leadership to the capable general Nikephoros Phokas . At the head of a huge fleet and army , Phokas sailed in June or July 960 , landed on the island , and defeated the initial Muslim resistance . A long siege of Chandax followed , which dragged over the winter into 961 , when the city was stormed on 6 March . The city was pillaged , and its mosques and walls were torn down . Muslim inhabitants were either killed or carried off into slavery , while the island ' s last emir Abd al - Aziz ibn Shuayb ( Kouroupas ) and his son al - Numan ( Anemas ) were taken captive and brought to Constantinople , where Phokas celebrated a triumph . The island was converted into a Byzantine theme , and the remaining Muslims were converted to Christianity by missionaries like Nikon " the Metanoeite " . Among the converts was the prince Anemas , who entered Byzantine service and fell at Dorostolon , in the war of 970 – 971 against the Rus ' . Legacy . The Arab period of Crete remains relatively obscure due to a paucity of surviving evidence regarding its internal history . Furthermore , other than a few place names recalling the presence of the Saracens , no major archaeological remains from the period survive , possibly due to deliberate Byzantine destruction after 961 . This has influenced the way the emirate is generally regarded : scholars , forced to rely mostly on Byzantine accounts , have traditionally viewed the Emirate of Crete through a Byzantine lens as a quintessential " corsair ' s nest " , surviving on piracy and the slave trade . The picture painted by the few and scattered references to the Cretan emirate from the Muslim world , on the other hand , is of an ordered state with a regular monetary economy and extensive trade links , and there is evidence that Chandax was a cultural centre of some importance . The survival of numerous gold , silver , and copper coins , of almost constant weight and composition , testifies to a strong economy and a high living standard among the population . The economy was strengthened by extensive trade with the rest of the Muslim world , especially with Egypt , and by a booming agriculture : the need to sustain an independent state , as well as access to the markets of the Muslim world , led to an intensification of cultivation . It is also possible that sugar cane was introduced to Crete at the time . It is unclear what happened to the island ' s Christians after the Muslim conquest ; the traditional view is that most were either converted or expelled . There is evidence from Muslim sources , however , for the continued survival of Christians on Crete , although according to the same sources the Muslims , whether descendants of the Andalusians , more recent migrants , or converts ( or any combination of these ) formed the majority . There is also some evidence of rival factions on the island , either Christian or Muslim , as when Theodosius the Deacon reports the " inhabitants of crags and caves " under their leader Karamountes descending from the mountains during the siege of Chandax by Nikephoros Phokas . It seems that the population of the countryside was left relatively alone , while the Muslim element ( including native converts ) predominated in the towns . List of emirs . The succession of the emirs of Crete has been established by Arab and Byzantine sources , but chiefly through their coinage . The dates of their reigns are therefore largely approximate :
