Year 949 (CMXLIX) was a common year starting on Monday of the Julian calendar.
Nikephoros II Phokas, Latinized Nicephorus II Phocas, was Byzantine emperor from 963 to 969. His career, not uniformly successful in matters of statecraft or of war, nonetheless greatly contributed to the resurgence of the Byzantine Empire during the 10th century. In the east, Nikephoros completed the conquest of Cilicia and retook the islands of Crete and Cyprus, opening the path for subsequent Byzantine incursions reaching as far as Upper Mesopotamia and the Levant; these campaigns earned him the sobriquet "pale death of the Saracens".
The Byzantine navy was the naval force of the Byzantine Empire. Like the state it served, it was a direct continuation from its Roman predecessor, but played a far greater role in the defence and survival of the state than its earlier iteration. While the fleets of the Roman Empire faced few great naval threats, operating as a policing force vastly inferior in power and prestige to the army, command of the sea became vital to the very existence of the Byzantine state, which several historians have called a "maritime empire".
The Arab–Byzantine wars were a series of wars between a number of Muslim Arab dynasties and the Byzantine Empire from the 7th to the 11th century. Conflict started during the initial Muslim conquests, under the expansionist Rashidun and Umayyad caliphs, in the 7th century and continued by their successors until the mid-11th century.
The second Arab siege of Constantinople was a combined land and sea offensive in 717–718 by the Muslim Arabs of the Umayyad Caliphate against the capital city of the Byzantine Empire, Constantinople. The campaign marked the culmination of twenty years of attacks and progressive Arab occupation of the Byzantine borderlands, while Byzantine strength was sapped by prolonged internal turmoil. In 716, after years of preparations, the Arabs, led by Maslama ibn Abd al-Malik, invaded Byzantine Asia Minor. The Arabs initially hoped to exploit Byzantine civil strife and made common cause with the general Leo III the Isaurian, who had risen up against Emperor Theodosius III. Leo, however, tricked them and secured the Byzantine throne for himself.
The first Arab siege of Constantinople in 674–678 was a major conflict of the Arab–Byzantine wars, and the first culmination of the Umayyad Caliphate's expansionist strategy towards the Byzantine Empire, led by Caliph Mu'awiya I. Mu'awiya, who had emerged in 661 as the ruler of the Muslim Arab empire following a civil war, renewed aggressive warfare against Byzantium after a lapse of some years and hoped to deliver a lethal blow by capturing the Byzantine capital of Constantinople.
The Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Muslim rule until conquered in turn by the Normans in the 11th century.
Abu Hafs Umar ibn Hafs ibn Shuayb ibn Isa al-Balluti, commonly known as Umar I of Crete, was the leader of a group of Andalusi refugees who seized control of Alexandria and, after being expelled from the city by the Abbasids, conquered the Byzantine island of Crete, becoming the first emir of Crete.
The Byzantine Empire was ruled by the Isaurian dynasty from 717 to 802. The Isaurian emperors were successful in defending and consolidating the empire against the caliphates after the onslaught of the early Muslim conquests, but were less successful in Europe, where they suffered setbacks against the Bulgars, had to give up the Exarchate of Ravenna, and lost influence over Italy and the papacy to the growing power of the Franks.
Between 780–1180, the Byzantine Empire and the Abbasid & Fatimid caliphates in the regions of Iraq, Palestine, Syria, Anatolia and Southern Italy fought a series of wars for supremacy in the Eastern Mediterranean. After a period of indecisive and slow border warfare, a string of almost unbroken Byzantine victories in the late 10th and early 11th centuries allowed three Byzantine Emperors, namely Nikephoros II Phokas, John I Tzimiskes and finally Basil II to recapture territory lost to the Muslim conquests in the 7th century Arab–Byzantine wars under the failing Heraclian Dynasty.
The Emirate of Crete was an Islamic state that existed on the Mediterranean island of Crete from the late 820s to the reconquest of the island by the Byzantine Empire in 961. Although the emirate recognized the suzerainty of the Abbasid Caliphate and maintained close ties with Tulunid Egypt, it was de facto independent.
The Thracesian Theme, more properly known as the Theme of the Thracesians, was a Byzantine theme in western Asia Minor. Created either in the mid-7th or the early 8th century as the settlement of the former Army of Thrace, after which it was named, it was one of the larger and more important themes of the Empire throughout its existence based on its proximity to Constantinople. The Thracesian Theme was one of the longest-lived themes, surviving until the region was conquered by the Turks in the early 14th century.
The Battle of Petroe, also known as the Battle of Hades, was fought on 20 August 1057 between two rival Byzantine armies: the loyalist forces of the Byzantine emperor Michael VI Stratiotikos under the proedros Theodore, and the supporters of the rebel general Isaac Komnenos.
The island of Crete came under the rule of the Byzantine Empire in two periods: the first extends from the late antique period to the conquest of the island by Andalusian exiles in the late 820s, and the second from the island's reconquest in 961 to its capture by the competing forces of Genoa and Venice in 1205.
The Theme of Cephallenia or Cephalonia was a Byzantine theme located in western Greece, comprising the Ionian Islands, and extant from the 8th century until partially conquered by the Kingdom of Sicily in 1185.
The Abbasid invasion of Asia Minor in 782 was one of the largest operations launched by the Abbasid Caliphate against the Byzantine Empire. The invasion was launched as a display of Abbasid military might in the aftermath of a series of Byzantine successes. Commanded by the Abbasid heir-apparent, the future Harun al-Rashid, the Abbasid army reached as far as Chrysopolis, across the Bosporus from the Byzantine capital, Constantinople, while secondary forces raided western Asia Minor and defeated the Byzantine forces there. As Harun did not intend to assault Constantinople and lacked ships to do so, he turned back.
The Battle of Andrassos or Adrassos was fought on 8 November 960 between the Byzantines, led by Leo Phokas the Younger, and the forces of the Hamdanid Emirate of Aleppo under the emir Sayf al-Dawla. It was fought in an unidentified mountain pass in the Taurus Mountains.
The siege of Chandax in 960-961 was the centerpiece of the Byzantine Empire's campaign to recover the island of Crete which since the 820s had been ruled by Muslim Arabs. The campaign followed a series of failed attempts to reclaim the island from the Muslims stretching as far back as 827, only a few years after the initial conquest of the island by the Arabs, and was led by the general and future emperor Nikephoros Phokas. It lasted from autumn 960 until spring 961, when the main Muslim fortress and capital of the island, Chandax was captured. The reconquest of Crete was a major achievement for the Byzantines, as it restored Byzantine control over the Aegean littoral and diminished the threat of Saracen pirates, for which Crete had provided a base of operations.
The sack of Aleppo in December 962 was carried out by the Byzantine Empire under Nikephoros Phokas. Aleppo was the capital of the Hamdanid emir Sayf al-Dawla, the Byzantines' chief antagonist at the time.
The Cretan expedition occurred between 911 and 912, when the Byzantine army invaded the island of Crete to recapture it, which was held by the Arabs. The expedition ended in failure for the Byzantine army.
