Byzantine-Seljuq War of 1207-11
Years: 1207 - 1211
For an empire that was surrounded by enemies the downfall of Byzantium became a greater probability and in 1204 the city of Constantinople had been sacked by soldiers of the Fourth Crusade bringing the Empire into another era of chaos.
The Seljuqs of Rum, under a new Sultan, Kaykhusraw, exploit this event and attack the port of Antalya in 1207, capturing it from the weakened splinter Empire of Nicaea.
The tide turns, however, in 1211 when the Sultan himself is killed in single combat by the Emperor of Nicaea at the Battle of Antioch on the Meander and from this point on the empire’s eastern frontier is more or less stabilized.

Near East (1108 – 1251 CE): Ayyubid Cairo, Crusader Tyre, Nubian Resilience, and the Nicaean–Seljuk Shore
Geographic and Environmental Context
The Near East includes Israel, Egypt, Sudan, western Saudi Arabia, western Yemen, most of Jordan, southwestern Cyprus, and western Turkey (Aeolia, Ionia, Doria, Lydia, Caria, Lycia, and the Troad), plus Tyre in extreme southwest Lebanon.
-
Anchors: the Nile Valley (Egypt–Sudan), the southern Levant (with Tyre as the Near East’s sole Levantine polity), Hejaz and western Yemen along Red Sea corridors, southwestern Cyprus, and western Anatolia’s Aegean littoral.
Climate and Environmental Shifts
-
The Medieval Warm Period (c. 950–1250) modestly lengthened growing seasons in the Nile Delta and Aegean valleys.
-
Nile flood variability peaked in the late 12th century but recovered under Ayyubid hydraulic repairs.
-
Red Sea monsoon timing underpinned predictable sailing between Yemen and Egypt.
Societies and Political Developments
-
Egypt (Fatimids → Ayyubids):
-
Fatimid rule ended in 1171; Ṣalāḥ al-Dīn (Saladin) founded the Ayyubid dynasty, recentralizing Egypt, Syria, and the Hejaz under Sunni rule.
-
Cairo remained the capital; al-Azhar continued as a major center of learning.
-
-
Sudan (Nubia):
-
Christian Makuria and Alodia endured south of Egypt under the Baqṭ framework; diplomacy and intermittent raids marked the frontier.
-
-
Southern Levant (Tyre):
-
Tyre fell to the Kingdom of Jerusalem in 1124, becoming a key Crusader port and artisanal hub (glass, textiles).
-
After 1187, Ayyubid–Crusader truces and wars alternated; by 1251, Tyre remained a principal Latin stronghold and brokerage point with Egypt and Cyprus.
-
-
Western Arabia (Hejaz):
-
Mecca and Medina acknowledged Ayyubid suzerainty; Hajj caravans tied the Hejaz into Cairo’s fiscal–logistics system.
-
-
Western Yemen:
-
Sulayhids waned after Queen Arwa (d. 1138).
-
Ayyubids conquered Yemen in 1174, then Rasulids (from 1229) established a durable sultanate centered on Aden/Zabid, allied to Red Sea trade.
-
-
Southwestern Cyprus:
-
After 1191–1192, the Lusignan Kingdom of Cyprus controlled the island; its southwestern ports provisioned Crusader Syria and traded with Egypt (overtly or via truces).
-
-
Western Anatolia (Aegean coast):
-
The Komnenian recovery (to 1180) secured the littoral; Myriokephalon (1176) checked Byzantine inland advances.
-
Post-1204, the Empire of Nicaea held the Ionian/Carian coast against the Seljuks of Rum and Latin enclaves; by 1251, Nicaea dominated the Aegean shore while interior Anatolia remained Turkish.
-
Economy and Trade
-
Cairo–Nile: grain, flax, and sugar surpluses financed the Ayyubid realm; waqf endowments sustained schools and hospitals.
-
Red Sea–Indian Ocean: Aden/Zabid funneled spices, aromatics, cottons, and Indian goods to Aydhab and Qūṣfor Cairo; Yemen exported sāqiya-irrigated produce.
-
Tyre: exported fine glassware, dyed textiles, and served as a transshipment port between Egypt, Cyprus, and Crusader Syria.
-
Western Anatolia & Cyprus: wine, oil, timber, and manufactures moved through Ionian harbors and Cypriot ports, with Nicaean/Latin convoys policing lanes.
-
Nubia: traded ivory, gold, and slaves for Egyptian grain and textiles.
Subsistence and Technology
-
Hydraulics: Ayyubids dredged canals and maintained barrages after flood failures; Yemeni terraces and sāqiyawheels stabilized highland yields.
-
Institutions: Sunni education expanded via madrasas (Ayyubid patronage), while al-Azhar remained a major scholarly forum.
-
Military–fiscal: Ayyubids balanced iqṭāʿ-like land assignments with cash pay; Nicaea fielded professional troops and revived shipyards.
-
Shipbuilding: lateen-rigged merchantmen and galleys plied the Red Sea and Aegean.
Movement and Interaction Corridors
-
Nile corridor: Upper Egypt ⇄ Fusṭāṭ–Cairo ⇄ Alexandria.
-
Red Sea: Aden/Zabid ⇄ Aydhab/Qūṣ ⇄ Cairo, keyed to monsoon cycles.
-
Aegean littoral: Nicaean and Latin fleets contested Smyrna–Ephesus–Rhodes routes; southwestern Cyprus provisioned Levantine ports.
-
Pilgrimage: Hajj caravans crossed the Hejaz; Coptic and Nubian pilgrimages linked Upper Egypt and Nubia.
-
Tyre’s roadstead: remained Egypt’s key Levantine interface after 1187.
Belief and Symbolism
-
Sunni revival: Ayyubids strengthened Sunni law and institutions; jurists and Sufi networks expanded.
-
Coptic and Nubian Christianity: persisted across the Nile and Sudan; Nubian cathedrals and monasteries retained regional influence.
-
Latin Christianity: entrenched in Tyre and Cyprus; Latin and Greek rites met in contested ports.
-
Judaism: communities in Cairo and Tyre sustained trade finance and scholarship.
Adaptation and Resilience
-
Hydraulic recovery in Egypt after the 1060s crises restored agrarian stability.
-
Maritime redundancy: with much of the Levant in Latin hands after 1099, Tyre and Cyprus kept Egyptian–Aegean trade viable via truces and convoying.
-
Frontier strategy: Byzantium (Nicaea) pivoted to coastal control; Seljuk iqṭāʿ funded cavalry in interior Anatolia.
-
Hejaz–Yemen integration: monsoon schedules and Hajj logistics stabilized Red Sea commerce despite shifting overlords.
Long-Term Significance
By 1251, the Near East formed a polycentric web:
-
Ayyubid Cairo dominated Nile–Red Sea exchange and Sunni learning.
-
Tyre—now Latin—anchored Levantine trade, linking Egypt and Cyprus to Crusader and Byzantine markets.
-
Nubia remained a Christian buffer south of Egypt.
-
Western Anatolia (under Nicaea) sustained Aegean commerce while the interior Turkified under Rum Seljuks.
-
Western Yemen’s Rasulids secured Aden’s role in Indian Ocean trade.
These strands bound Nile, Hejaz–Yemen, Tyre–Cyprus, and the Aegean coast into a resilient system that would frame 13th-century confrontations and exchanges among Ayyubids/Mamluks, Crusaders, and Nicaea/Rum Seljuks.
The Seljuqs of Rum, under a new Sultan, Kaykhusraw, exploit this situation and attack the port of Antalya in 1207, capturing it from the weakened splinter Empire of Nicaea.
The tide turns, however, when the Seljuq Sultan himself is killed in single combat by the Greek Emperor of Nicaea at the Battle of Antioch on the Meander in 1211, and the empire’s eastern frontier is more or less stabilized from this point on.
Kaykhusraw, Seljuq Sultan of Rum, has reunified the Seljuq state and begun to expand at the expense of what is left of the Greek Empire in the west and north.
His most important achievements include the capture of the harbor of Antalya (Attalia) on the Mediterranean coast in 1207 and the conclusion of commercial treaties with the Italian maritime republics.
Hereafter, the Seljuqs are no longer limited to the interior of the Anatolian plateau, a fact of great economic as well as political significance.
Theodore Laskaris had not at first claimed the imperial title, perhaps because his father-in-law and his brother were both still living, perhaps because of the imminent Latin invasion, or perhaps because there was no Patriarch of Constantinople to crown him emperor.
Proclaimed emperor in 1205, he had invited Patriarch John Kamateros to Nicaea, but John had died in 1206 before crowning Theodore.
Theodore appoints Michael IV as the new Patriarch and is crowned by him in March 1208.
Theodore defends his infant empire not only against the crusaders but also against David Komnenos, the rival Greek emperor in Trebizond to the east on the Black Sea, and against the Seljuq Turks.
Exiled emperor Alexios III Angelus, Theodore's father-in-law, has accepted Kaykhusraw’s offer of asylum.
Alexios demands Theodore's crown and, when he fails to persuade Theodore to abdicate, the Seljuqs of Rüm invade Nicaea to force Theodore's abdication, but the Nicaean forces repulse the attack.
Latin emperor Henry, having defeated the Bulgarians in Europe between 1209 and 1211, holds the forces of Theodore Lascaris at bay.
Kaykhusraw, having failed to persuade Theodore to abdicate in favor of Alexios, marches against Theodore a second time with Seljuq forces in the spring of 1211.
The Seljuq army, meeting in battle in the Meander Valley near Antioch-on-the-Meander, is initially victorious, with Laskaris' eight hundred Latin mercenary cavalry bearing the brunt of the casualties due to their impetuous charge; once exhausted by their onset, the Latins are struck in the flank and rear by the Seljuq forces.
However, the Seljuq troops stop to plunder the Nicaean camp, allowing Theodore's forces to rally and counterattack the now disorganized Turks.
Theodore seeks out Kaykhusraw I and engages him in single combat, killing him.
Sources relate that Laskaris was initially unhorsed by the sultan, but he subsequently brought Kaykhusraw down by hacking at his mount's legs; once the sultan was thrown to the ground Laskaris stabbed him to the heart.
The Seljuq forces are routed.
The former emperor Alexios, Laskaris' father-in-law, is captured during the battle and subsequently imprisoned, ending his days in enforced monastic seclusion at Nicaea.
Known also as the Battle of Alaşehir, the Turkish defeat ensures continued Nicaean hegemony of the Aegean coast of Asia Minor.
The battle has freed Nicaea from Seljuq pressure but Laskaris' army has suffered heavily.
In particular his very effective Latin mercenary cavalry has been almost destroyed.
As a result, Laskaris cannot adequately defend his territory from an attack by the Latin Empire of Constantinople and he has to cede some territory bordering the Sea of Marmara.
However, the victory gives Laskaris considerable prestige and the capture of Alexios ended internal opposition to his rule.
The battle is the last major encounter between the Seljuqs and the Greeks.
Ultimately, the Seljuqs have failed to take all of Asia Minor.
The succession of 'Izz ad-Din Kaykaus’, the eldest son of Kaykhusraw,
is challenged by his two younger brothers, Kayferidun Ibrahim and the future Kayqubad I following their father's death in the Battle of Alaşehir in 1211.
Kayqubad initially garners some support among the neighbors of the sultanate, Leo II, the king of Cilician Armenia, and Tughrilshah, his uncle and the independent ruler of Erzurum.
At the same time, Kayferidun imperils the recently acquired port of Antalya by seeking aid from the Cypriot Franks.
Most of the emirs, as the powerful landed aristocracy of the sultanate, support Kaykaus.
From his base in Malatya, …
…Kaykaus seizes Kayseri, then …
…Konya, inducing Leo to change sides.
Kayqubad is forced to flee to …
"{Readers} take infinitely more pleasure in knowing the variety of incidents that are contained in them, without ever thinking of imitating them, believing the imitation not only difficult, but impossible: as if heaven, the sun, the elements, and men should have changed the order of their motions and power, from what they were anciently"
