Shown on the map: AD 990–1039
Peak area: 819k km²
Region: Central Asia

Overview

The Seljuk (Saljuq) dynasty was an Oghuz Turkic Sunni Muslim dynasty that rose from the Central Asian steppe to found the Great Seljuk Empire (1037–1194), plus branch states in Kerman (1041–1186), Syria, and most famously the Sultanate of Rum in Anatolia (1077–1308). Culturally Persianate, the Seljuks are the paradigmatic case of the Turco-Persian tradition: Turkic rulers patronizing Persian culture, administration, and letters. (Note on the peak-area figure of ~819,000 km² in the project data: this does not match the Great Seljuk Empire's maximum, usually estimated at ~3.9 million km² under Malik Shah I; it may reflect a specific branch or date in the dataset and should be flagged for verification.)

Origins and ethnolinguistic background

The Seljuks sprang from the Qiniq (Kinik) branch of the Oghuz Turks, who lived in the Oghuz Yabgu state on the Kazakh steppe north of the Caspian and Aral seas. The dynasty's founder, Seljuk Beg, is described in some sources as a descendant of the Khazar commander Tuqaq who had served the Khazar king. After a quarrel with the Oghuz yabghu, Seljuk led his clan to the lower Syr Darya (Jand/Cend), where they converted to Sunni (Hanafi-Maturidi) Islam around 985. They served as frontier auxiliaries for the Samanids and then for Mahmud of Ghazna before pushing into Khorasan.

Chronology and major rulers

Seljuk's grandsons Tughril Beg and Chaghri Beg defeated the Ghaznavids at Nasa (1035) and decisively at Dandanaqan (1040), proclaiming themselves rulers of Khorasan with Nishapur as capital. Tughril took Isfahan (1050/51), then Baghdad in 1055, ending Buyid control and becoming protector ("sultan") of the Abbasid caliph — hence the Seljuks' fame as restorers of Sunni unity. Alp Arslan (r. 1063–1072) conquered Georgia and Armenia and crushed the Byzantines at Manzikert (1071), opening Anatolia to Turkmen settlement. Under Malik Shah I (r. 1072–1092) the empire reached its greatest extent — from Central Asia to the Mediterranean — administered by the great vizier Nizam al-Mulk, founder of the Nizamiyya madrasa network. The Seljuks also asserted suzerainty over the Kara-Khanids of Transoxiana (from 1089), received tribute from the Shirvanshahs, and intermarried with both houses.

Government, economy, culture, religion

Government followed the Persian bureaucratic model staffed by Iranian viziers and scribes ("the Turks were illiterate and uncultivated when they arrived in Khurasan and had to depend on Iranian scribes," as the Saljuq-nama tradition admits). Persian became the language of administration and culture, while the Turkic practice of dividing provinces among royal sons (appanages) fostered the dynastic fragmentation that undermined the empire. The Seljuks patronized Sunni orthodoxy, architecture (the Great Mosque of Isfahan, the Toghrol Tower, the Kharraqan towers), metalwork, and pottery. The Assassin (Nizari Ismaili) movement arose as their deadly internal foe — Nizam al-Mulk's assassination in 1092 is attributed to them.

Decline and fall

Succession wars after Malik Shah's death (1092) splintered the empire; Ahmad Sanjar (r. 1118–1153) was the last effective Great Seljuk, ruling the east until his catastrophic defeat by the Qara Khitai at Qatwan (1141) and capture by rebellious Oghuz (1153). The western (Iraqi/Hamadan) line persisted as atabeg-dominated figureheads until Toghrul III fell in battle against the Khwarazmshah Tekish in 1194. In Anatolia, the Sultanate of Rum (its own branch) survived until the Mongol victory at Köse Dağ (1243) reduced it to an Ilkhanid protectorate; it died out early in the 14th century. The last collateral emirs (Kubadoğulları of Samsun) submitted to the Ottomans in 1422.

Legacy

The Seljuks reoriented the Islamic world: Turkic military power joined to Persian statecraft and Sunni revival, the madrasa system, the opening of Anatolia to the Turks (the distant root of Turkey itself), and a cultural model inherited by the Khwarazmians, the Anatolian beyliks, and ultimately the Ottomans.
