The Role of the Seljuk Turks in Triggering the First Crusade

Episode 22: The Turks in Anatolia and India

Barbarian Empires of the Steppes (2014)

Dr Kenneth Harl

Film Review

This lecture covers the conquest of the Anatolia peninsula by Seljuk Turks and the conquest of northern India by the Ghaznavid Turks.

After the Seljuk Turks took control of Baghdad (see 9th Century AD: Mass Migration of Uighur Turks to China Lead to Rise of Seljuk Turks on the Steppes), their biggest political/military challenge was the Shi’a caliphs operating out Cairo. Following the withdrawal of the Seljuk army from Baghdad in 1057, opponents to Seljuk rule sought support from the Fatimid (Shi’ar)my in Cairo. The latter occupied Baghdad for 40 days before being expelled by the Seljuk army. To suppress the Fatimid regime, the Seljuks subsequently invaded Cairo, the Byzantine Empire (allied with the Fatimid regime), Syria, Medina and Mecca.

This ongoing conflict caused major disruption in the Christian pilgrimage routes to Jerusalem (agreed between the Byzantines and the Abassid Caliphate), inspiring Pope Urban II to launch the first Crusade in 1095, nominally to restore Christian access to Jerusalem.

This is the time line Harl presents:

1071 Seljuks open up the eastern Anatolia peninsula to Turkish settlers, cutting the area controlled by the Byzantine Empire in half.

1081 Byzantine Emperor calls on western Europe to send mercenaries to help liberate eastern Anatolia. Pope Urban II “mistakenly” interprets this as a call to “liberate” Jerusalem and mobilizes 50,000 European mercenaries to join the first Crusade. Totally unprepared to confront European cavalry, the Turks suffer initially suffer stunning defeat. Nevertheless the Crusaders are ultimately unsuccessful in driving the Turks, who created a Turkish homeland in eastern Anatolia, from the Anatolian plateau. Christian farmers Initially pay tribute to Seljuk Turk rulers, but ultimately most of eastern Anatolia reverts to grasslands and nomadic pastoralism.

1204 Europeans Crusaders respond by sacking Constantinople. This backfires, shifting the balance of power in Anatolia to the Seljuk Turks.

On the southeaster steppes, Ghaznavad Turks repeatedly invade India during the 12th century. Beginning in 1101, they gradually brring first Lahore, Peshawar and other Indian cities under Turkish (Muslim) control. By 1192, the Turks have conquered Dehli.

Unlike the Seljuk conquest of eastern Anatolia, the Turkish occupation of India is purely military. With no grasslands to support pastoral nomadic tribes, northern India never attracted Turkish settlers.

The Multiethnic Origins of the Muslim Conquest

Episode 19: Islam and the Caliphates

Barbarian Empires of the Steppes (2014)

Dr Kenneth Harl

Film Review

In this lecture, Harl focuses mainly on the battle for control of the Muslim caliphate following the birth of Islam in the 7th century AD.

The key dates he cites are

622 AD – the prophet Muhammad migrates to Medina from Mecca owing to conflict with Mecca elites.

632 AD – Muhammad dies after returning to Mecca with his followers.

633 AD – Muslim armies conquer the Sassanid Empire (Persia).

634-634 AD – Muslim armies conquer the Middle East Byzantine provinces and the Levant. [1]

641 AD – Muslim armies conquer Egypt (where they are welcomed after seven centuries of oppressive Roman rule).

642 AD – Muslim armies march east across North Africa and west into lower Indus Valley (modern day Pakistan).

656 AD – Arab army mutinies in Egypt (over lack of pay), marches back to Medina and kills the reigning caliph Uthman, who they replace with Ali, a Shia [2] cousin of Muhammad. A civil war ensures, with the Sunni Ummayad caliphate eventually assuming power  and establishing Damascus as their capitol.

700 AD The Sunni Ummayad faces serious military (suffering defeat in their efforts to conquer Constantinople, the Khazars and the Turks in Transoxiana [3], political and fiscal challenges. Muslim soldiers (many of whom are nomad mercenaries) garrisoned in the steppes cities become increasingly independent and “rapacious.”

711 AD – Muslim armies cross into Iberian peninsular, smash the Visigoth kingdom and overrun most of Spain.

749 AD – Umayyad caliphate overthrown by a mixed army (many of whom identify as Shia) of Arab tribal regiments and Persian converts. Replaced by Abbasid caliphate (descended from Muhammad’s uncle), who move capitol to Baghdad. [4]

809 AD – New civil war results from the conflict between the brothers al-Amin and al-Ma’mun over the Abbasid Caliphate succession.

909 AD – organized Berbers sweep across North Africa to occupy Egypt where they set up a Fatima (Shia) caliphate which, in alliance with the Byzantine Empire, takes over Baghdad and much of the Levant, as well as the holy cities on the Arabian peninsula.

945 AD – Seljiud Turks who have converted to Islam invade from the East and restore power in Baghdad to the Abbassid caliphs.


[1] The Levant refers to a large ancient historical area on the eastern shores of the Mediterranean.

[2] Shia Islam, the second largest branch of the religion, holds that Muhammad designated his cousin Ali as his successor.

[3] Transoxiana is the Roman name for the central steppes region roughly corresponding to Uzbekistan, Tajikistan and southern Kazakhstan and Kyrgyzstan.

[4] According to Harl, this move cements the caliphate in the Persian (Sassanid) cultural world and turns the empire from an Arab empire to a multi-ethnic Muslim empire. Ultimately 34 of the 37 Abbassid caliphs were sons of non-Arab Persian slaves.
