Rum, Sultanate of
State | Defunct
1077 CE to 1308 CE
The Sultanate of Rum[a] was a culturally Turco-Persian Sunni Muslim state, established over conquered Byzantine territories and peoples (Rum) of Anatolia by the Seljuk Turks following their entry into Anatolia after the Battle of Manzikert in 1071. The name Rum was a synonym for the medieval Eastern Roman Empire and its peoples, as it remains in modern Turkish. The name is derived from the Aramaic (romī) and Parthian (frwm) names for ancient Rome, via the Greek Ῥωμαῖοι (Romaioi) meaning the Anatolia.
The Sultanate of Rum seceded from the Seljuk Empire under Suleiman ibn Qutalmish in 1077. It had its capital first at Nicaea and then at Iconium. It reached the height of its power during the late 12th and early 13th century, when it succeeded in taking key Byzantine ports on the Mediterranean and Black Sea coasts. In the east, the sultanate reached Lake Van. Trade through Anatolia from Iran and Central Asia was developed by a system of caravanserai. Especially strong trade ties with the Genoese formed during this period. The increased wealth allowed the sultanate to absorb other Turkish states that had been established following the conquest of Byzantine Anatolia: Danishmendids, House of Mengüjek, Saltukids, Artuqids.
The Seljuk sultans bore the brunt of the Crusades and eventually succumbed to the Mongol invasion at the 1243 Battle of Köse Dağ. For the remainder of the 13th century, the Seljuks acted as vassals of the Ilkhanate. Their power disintegrated during the second half of the 13th century. The last of the Seljuk vassal sultans of the Ilkhanate, Mesud II, was murdered in 1308. The dissolution of the Seljuk state left behind many small Anatolian beyliks (Turkish principalities), among them that of the Ottoman dynasty, which eventually conquered the rest and reunited Anatolia to become the Ottoman Empire.

The Near and Middle East (820 – 1107 CE): Abbasid Fragmentation, Fatimid Cairo, and the Gulf of Frankincense
Geographic and Environmental Context
Between the Tigris–Euphrates heartlands and the Nile Valley, across the Caucasus, Levant, Arabian deserts, and Red Sea–Indian Ocean corridors, the Near and Middle East formed one of the most interconnected and volatile regions of the early second millennium.
Its landscapes ranged from Mesopotamian canal plains and Persian qanāt belts to Syrian steppe margins, Caucasian uplands, Arabian incense valleys, and Egypt’s deltaic floodplains.
Cities such as Baghdad, Rayy, Tabriz, Cairo, Tyre, and Aden anchored a web of trade routes linking Byzantine Anatolia, Central Asia, India, and East Africa.
Climate and Environmental Shifts
Throughout this period, stable late-Holocene conditions supported agricultural and maritime prosperity.
The Tigris–Euphrates canals, qanāt systems of Iran, and Syrian norias sustained irrigated cores.
The Medieval Warm Period (after c. 950) modestly improved growing seasons in Egypt and western Anatolia, though the 1060s Nile failure precipitated crisis and reform under the Fatimids.
In the Gulf and southern Arabia, arid stability continued; monsoon-fed groves in Dhofar sustained incense cultivation, while Red Sea and Indian Ocean winds structured predictable sailing cycles.
Societies and Political Developments
Fragmentation and Transformation in the Abbasid Realm (820–963 CE)
During the later Abbasid centuries, imperial unity gave way to regional dynasties and shifting religious allegiances.
-
In Iraq and Iran, local powers—the Tahirids of Khurasan, Saffarids of Sistan, and Samanids of Transoxiana—asserted autonomy.
-
In 945, the Buyids seized Baghdad, establishing a Shi‘i-leaning amirate over the caliphate.
-
Syria and Cilicia oscillated between Abbasid, Tulunid, and later Ikhshidid governors; frontier thughūr (Cilicia) endured Byzantine–Muslim warfare.
-
In the Caucasus, the Bagratid kings of Armenia (885) and Bagrationi princes of Georgia consolidated Christian monarchies.
-
In eastern Arabia, the Qarmatians (from 899)—a radical Isma‘ili movement—dominated the al-Ahsa–Qatif oasis, raiding pilgrim routes and challenging Abbasid legitimacy.
-
Oman preserved Ibāḍī autonomy through coastal and oasis sheikhdoms.
-
The northeastern coast of Cyprus and northern Lebanon (Tripoli) remained contested or semi-autonomous trade nodes.
The Fatimid and Byzantine Ascendancy (964–1107 CE)
From the late tenth century, the regional axis shifted westward and southward.
-
Egypt, seized by the Fatimids in 969, became the intellectual and commercial core of the Isma‘ili world. Cairo and al-Azhar (970) emerged as twin centers of government and scholarship.
-
After the Nile crisis of the 1060s, Vizier Badr al-Jamālī restructured army and finance, restoring stability.
-
The Nubian kingdoms of Makuria and Alodia maintained Christian sovereignty under the Baqt treaty, linking Upper Egypt and the Sudanese gold and ivory trade.
-
In the southern Levant, Tyre remained a Fatimid-aligned port and cultural hub even after the First Crusade (1099), functioning as Egypt’s last Levantine lifeline.
-
Across western Arabia, Mecca and Medina remained under shifting control but continued as pilgrimage and trade nexuses of the Red Sea.
-
In western Yemen, a succession of Ziyadid, Yufirid, Najahid, and Sulayhid dynasties ruled; under Queen Arwa al-Sulayḥī (from 1067), Yemen entered a period of prosperity and Fatimid-aligned reform.
-
In western Anatolia, the Byzantine themes of Ionia and Caria faced Seljuk incursions after Manzikert (1071), yet by 1107, coastal cities and southwestern Cyprus still operated within Byzantine maritime networks.
Southeast Arabia: Frankincense and Maritime Crossroads (964–1107 CE)
To the southeast, Hadhramaut and Dhofar remained the incense heartlands.
-
Tribal principalities controlled frankincense wadis and exported resins via Aden into the Fatimid trade sphere.
-
Socotra, midway between Aden and India, alternated among Abbasid, Omani, and local rule, hosting Muslim, Christian, and mixed-faith communities.
-
The Empty Quarter and Najran corridors stayed under Bedouin control, guarding wells and caravan routes.
Economy and Trade
Agrarian surpluses and maritime commerce sustained this vast region.
-
Mesopotamia and Iran: irrigation-fed cereals, dates, flax, cotton, and silk formed the economic core.
-
Caucasus: exported metals, wine, and timber through Tabriz–Rayy–Khurasan and Derbent corridors.
-
The Gulf: pearls from Bahrain/Qatif, Arabian horses, and dates moved to India; Hormuz’s precursors and Omani ports connected Gulf and Indian markets.
-
Egypt and the Red Sea: Fatimid fleets carried grain, sugar, and flax northward and imported spices, textiles, and aromatics from India and Yemen.
-
Tyre exported glass, dyed textiles, and silverware; its port linked Fatimid Egypt to Byzantium and post-Crusade markets.
-
Western Anatolia and Cyprus shipped timber, wine, and oil; Byzantine coins and Fatimid dinars circulated concurrently.
-
Southeast Arabia exported frankincense, myrrh, dragon’s blood, and pearls; Socotra became a vital provisioning and exchange stop for sailors en route to India.
Regional and transoceanic trade tied Baghdad, Cairo, Aden, Basra, Hormuz, Tyre, and Byzantium into a unified commercial matrix.
Subsistence and Technology
-
Irrigation and hydraulics: Abbasid–Buyid qanāts, Fatimid canal dredging, and Yemeni terrace farming exemplified environmental control.
-
Architecture: Abbasid domes, Fatimid mosques and palaces, and mountain fortresses of Armenia and Yemen reflected plural artistic traditions.
-
Industry: Syrian and Lebanese glass, Persian textiles, Egyptian sugar, and Omani shipbuilding drove production.
-
Maritime technology: lateen-rigged merchantmen, stitched Omani hulls, and Red Sea galleys expanded regional range.
-
Education and law: Cairo’s al-Azhar and Baghdad’s madrasas became twin pillars of Islamic scholarship, influencing law from North Africa to Iran.
Movement and Interaction Corridors
-
Overland routes:
-
Tabriz–Rayy–Nishapur linked the Caspian and Khurasan.
-
Mosul–Aleppo–Cilicia formed the Byzantine–Muslim frontier artery.
-
Baghdad–Basra–Gulf joined caravan and maritime exchange.
-
Caucasus passes (Darial, Derbent) tied Eurasia’s steppe to Iran and Armenia.
-
-
Maritime routes:
-
Red Sea–Aden–Socotra–India formed the incense and spice conveyor of the western Indian Ocean.
-
Aegean–Cyprus–Levantine lanes connected Byzantine and Fatimid economies.
-
-
Pilgrimage and religious routes:
-
The Hajj linked Cairo, Damascus, and Mecca; Nubian and Coptic pilgrims used the Nile corridor.
-
Qarmatian disruptions (late ninth–tenth century) reshaped caravan security until their decline.
-
Belief and Symbolism
Religion shaped politics and art across the region’s diverse civilizations.
-
Abbasid Baghdad upheld Sunni orthodoxy, while Buyid Shi‘i patronage introduced dual authority in the caliphal capital.
-
Fatimid Cairo represented Isma‘ili Shi‘ism, expressed through ceremonial procession and missionary (daʿwa) networks.
-
Seljuk and Sunni revivalism later strengthened orthodox learning through Nizāmiyya madrasas.
-
Armenia and Georgia thrived as Christian kingdoms; Nubia maintained strong Coptic ties.
-
Oman and Hadhramaut preserved Ibāḍī and emerging Sufi traditions.
-
Socotra remained a unique enclave of overlapping Christian, Muslim, and local rituals.
-
Byzantine Orthodoxy and Islamic scholarship met in Aegean borderlands, each influencing Mediterranean art and philosophy.
Adaptation and Resilience
Regional resilience stemmed from environmental management and trade flexibility:
-
Canal repair and Nile engineering in Fatimid Egypt restored food security after crisis.
-
Maritime redundancy—using Tyre and Red Sea routes—sustained commerce during wars.
-
Nomadic–sedentary alliances in Arabia stabilized caravan systems.
-
Hydraulic innovation and mountain terrace farming in Yemen and Iran prevented ecological decline.
-
Religious institutions—mosques, monasteries, and madrasas—served as networks of welfare, education, and credit that buffered communities during political upheaval.
Long-Term Significance
By 1107 CE, the Near and Middle East had evolved into a polycentric, commercially integrated, and religiously diverse region:
-
Fatimid Cairo dominated Nile–Red Sea exchange and became the intellectual capital of the Islamic world.
-
Baghdad remained a symbolic caliphal seat, overshadowed by Buyid and later Seljuk power.
-
Armenia and Georgia flourished as Christian highland monarchies.
-
Byzantine Anatolia held its Aegean shores against Seljuk incursions.
-
The Gulf and Southeast Arabia prospered through frankincense, pearls, and seaborne trade, linking Arabia with India and East Africa.
-
Yemen and the Hejaz, under Sulayhid and Fatimid influence, mediated the pilgrimage and spice routes.
-
Nubia and Tyre preserved Christianity and commerce amid rising Crusader–Muslim rivalry.
The eleventh century thus marked a moment when no single empire commanded the region, yet its networks of irrigation, scholarship, and seafaring produced an enduring unity—one sustained by faith, trade, and the disciplined adaptation of societies to land and sea alike.
Middle East (820 – 963 CE): Abbasid Fragmentation, Caucasian Kingdoms, and the Qarmatian Gulf

Long-Term Significance
By 963, the Middle East was a polycentric field: Buyid Baghdad, Armenian–Georgian crowns, Ikhshidid Syria/Cilicia, and a Qarmatian-dominated Gulf—frameworks that would channel Fatimid, Seljuk, and Byzantine surges in the next age.
The Seljuks win control of most of Anatolia within ten years of the Battle of Manzikert.
The Seljuk sultanate in Baghdad, although successful in the west, reels under attacks from the Mongols in the east and is unable—indeed unwilling—to exert its authority directly in Anatolia.
The ghazis carve out a number of states here, under the nominal suzerainty of Baghdad, states that are continually reinforced by further Turkish immigration.
The strongest of these states to emerge is the Seljuk sultanate of Rum ("Rome," i.e., Byzantine Empire), which has its capital at Konya (Iconium).
Rum becomes dominant over the other Turkish states during the twelfth and thirteenth centuries.
The society and economy of the Anatolian countryside are unchanged by the Seljuks, who have simply replaced Greek Christian officials with a new elite that is Turkish and Muslim.
Conversion to Islam and the imposition of the language, mores, and customs of the Turks progresses steadily in the countryside, facilitated by intermarriage.
The cleavage widens, however, between the unruly ghazi warriors and the state-building bureaucracy in Konya.
The success of the Seljuk Turks stimulates a response from Latin Europe in the form of the First Crusade.
A counteroffensive launched in 1097 by the emperor in Constantinople with the aid of the crusaders deals the Seljuks a decisive defeat.
Konya falls to the crusaders, and after a few years of campaigning imperial Greek rule is restored in the western third of Anatolia.
Nikephoros Melissenos was probably born circa 1045 at Dorylaeum, where his family had extensive estates.
Through both his father and his mother, he is of aristocratic descent: his father belongs to the Bourtzes line, while his mother to the illustrious Melissenos family, which dates back to the eighth century and has produced several distinguished generals.
Sometime before 1067, Nikephoros had married Eudokia Komnene, the second daughter of the Domestic of the Schools John Komnenos and Anna Dalassene and sister of the future Byzantine emperor Alexios I Komnenos.
They have at least one known son, who is named John Komnenos.
Melissenos had held the rank of magistros and the post of governor (doux) of Triaditza (modern Sofia) for some time during the 1060s.
In 1070, he joins the field army commanded by his eldest brother-in-law, the protostrator Manuel Komnenos, in a campaign against the Seljuq Turks.
The campaign ends in defeat near Sebasteia (modern Sivas), and Melissenos along with Manuel Komnenos are captured by a Turkish chieftain whom the Greeks called Chrysoskoulos.
Manuel, however, quickly persuades the Turk to enter into imperial service, and their captivity ends.
The Turkish conquest of Nicaea and Nicomedia prompts Emperor Michael to appeal to Pope Gregory VII for aid against the Seljuqs, promising in return his support for the reunification of the Roman Catholic and Orthodox churches.
In need of help to uphold his unstable throne, Michael arranges the marriage of his son, Constantine, to one of Robert Guiscard's daughters, Helen.
The emperor has fallen increasingly under the influence of Nicephoritzes, an official who attempts to create a state monopoly in grain.
His policy not only angers the great landowners but also leads to higher prices and discontent among the people.
When rioting breaks out in Constantinople, two rival commanders, Nikephoros Bryennios and Nikephoros Botaneiates, each proclaims himself emperor, respectively, at Adrianople and at Nicaea.
Bryennios assembles an army of Thracians, Bulgarians, Macedonians, Sclavonians, Italians, Franks, Uzes (Cumans) and Greeks.
In November 1077, his forces reach the walls of Constantinople.
Unconcerned about the inhabitants of Constantinople, he allows his troops to plunder and burn the city's suburbs.
The conduct of his troops produces so determined an opposition to his claims, that the detested Michael forces him to raise the siege and retreat into Thrace, using the excuse of a Pecheneg incursion into Thrace as cover.
Suleiman is the son of Qutalmish, who had struggled unsuccessfully against his cousin Alp Arslan for the throne of Great Seljuq Empire.
When Kutalmish died in 1064, Suleiman had fled with his three brothers into the Taurus Mountains and there sought refuge with Turkmen tribes living beyond the borders of the empire.
Alp Arslan had responded by launching a series of punitive expeditions against them.
Of the four brothers, Suleiman alone has survived the raids and has been able to consolidate his leadership of the Turkmen.
Suleiman has been appointed governor of the northwestern provinces and assigned to completing the invasion of Anatolia.
An explanation for this choice can only be conjectured from Ibn al-Athir’s account of the battle between Alp-Arslan and Qutalmish, in which he writes that Alp-Arslan wept for the latter's death and greatly mourned the loss of his kinsman.
The emperor Michael VII seeks the help of Suleiman in 1078 against Nikephoros Botaneiates, the commander of the Anatolic Theme, who has challenged the emperor for the throne.
Suleiman intercepts Botaneiates' small force between Cotyaeum and Nicaea, whereupon the usurper persuades Suleiman to join his rebellion by offering him incentives superior to those of the emperor.
Nikephoros' bid for power is successful, and in return for their support Suleiman's Turkmen are allowed to settle on the Asiatic side of the Bosporus, near Constantinople itself.
Nikephoros Botaneiates, who belongs to the military aristocracy of Asia Minor and who is related to the powerful Phocas family, had become commander of the Anatolic theme, and, with some help from Suleiman, had been proclaimed emperor on January 7, 1078, by his supporters there.
He enters the capital three months later to claim the throne.
The aristocracy and clergy ratify his imperial claim, having already deposed Michael, who had abdicated on March 31, 1078.
The aged Botaneiates (he is seventy-six), as Nikephoros III, offers Bryennios the rank of Caesar and his nomination as heir to the throne if he will submit.
Bryennios agrees in principle to the offer of Emperor Nikephoros III Botaneiates, but adds a few conditions of his own, and sends the ambassadors back to Constantinople for confirmation.
Botaneiates, who likely had initiated negotiations only to gain time, rejected Bryennios's conditions, and sends the young Alexios Komnenos against him with an army composed of Greeks, Franks and Turkish cavalry.
Despite possessing a significantly superior army, at the Battle of Kalavrye, near the river Halmyros, Bryennios is defeated and captured.
He is subsequently blinded.
As he no longer poses a threat, Nikephoros III allows his estates and property to be returned to him, and gives Bryennios new honors.
