When Seljuk, the leader of the Seljuk clan, had a falling out with Yabghu, the supreme chieftain of the Oghuz, he split his clan from the bulk of the Oghuz Turks and set up camp on the west bank of the lower Syr Darya. Around 985, Seljuk converted to Islam.[15] In the 11th century, the Seljuks migrated from their ancestral homelands into mainland Persia, in the province of Khurasan, where they encountered the Ghaznavids. The Seljuks defeated the Ghaznavids at the Battle of Nasa Plains in 1035. Seljuk's grandsons, Tughril and Chaghri, received the insignias of governor, grants of land, and were given the title of dehqan.[16] At the Battle of Dandanaqan, they defeated a Ghaznavid army, and after a successful siege of Isfahan by Tughril in 1050/51,[17] established the Great Seljuk Empire. The Seljuks mixed with the local population and adopted the Persian culture and Persian language in the following decades.[18][19][20][21][22]
The "Great Seljuks" were heads of the family; in theory their authority extended over all the other Seljuk lines, although in practice this often was not the case. Turkic custom called for the senior member of the family to be the Great Seljuk, although usually the position was associated with the ruler of western Persia.
Khwarazmian dynasty replaces the Seljuk dynasty. From 1157, the Oghuz took control of much of Khurasan, with the remainder in the hands of former Seljuk emirs.
Muhammad's son Mahmud II succeeded him in western Persia, but Ahmad Sanjar, who was the governor of Khurasan at the time being the senior member of the family, became the Great Seljuk Sultan.
The rulers of western Persia, who maintained a very loose grip on the Abbasids of Baghdad. Several Turkic emirs gained a strong level of influence in the region, such as the Eldiguzids.

On the contrary, it was they who voluntarily became Persians and who, in the manner of the great old Sassanid kings, strove to protect the Iranian populations from the plundering of Ghuzz bands and save Iranian culture from the Turkoman menace."

Bosworth, E. van Donzel and W.P. Heinrichs. Brill, 2009: "Culturally, the consisting of the Seljuq Empire marked a further step in the dethronement of Arabic from being the sole lingua franca of educated and polite society in the Middle East. Coming as they did through a Transoxania which was still substantially Iranian and into Persia proper, the Seljuqs with no high-level Turkish cultural or literary heritage of their own – took over that of Persia, so that the Persian language became the administration and culture in their land of Persia and Anatolia. The Persian culture of the Rum Seljuqs was particularly splendid, and it was only gradually that Turkish emerged there as a parallel language in the field of government and adab; the Persian imprint in Ottoman civilization was to remain strong until the 19th century.
^Ehsan Yarshater, "Iran" in Encyclopedia Iranica: "The ascent of the Saljuqids also put an end to a period which Minorsky has called "the Persian intermezzo" (see Minorsky, 1932, p. 21), when Iranian dynasties, consisting mainly of the Saffarids, the Samanids, the Ziyarids, the Buyids, the Kakuyids, and the Bavandids of Tabarestan and Gilan, ruled most of Iran. By all accounts, weary of the miseries and devastations of never-ending conflicts and wars, Persians seemed to have sighed with relief and to have welcomed the stability of the Saljuqid rule, all the more so since the Saljuqids mitigated the effect of their foreignness, quickly adopting the Persian culture and court customs and procedures and leaving the civil administration in the hand of Persian personnel, headed by such capable and learned viziers as ‘Amid-al-Molk Kondori and Nezam-al-Molk."
^C.E. Bosworth, "Turkish expansion towards the west", in UNESCO History of Humanity, Volume IV: From the Seventh to the Sixteenth Century, UNESCO Publishing / Routledge, 2000. p. 391: "While the Arabic language retained its primacy in such spheres as law, theology and science, the culture of the Seljuk court and secular literature within the sultanate became largely Persianized; this is seen in the early adoption of Persian epic names by the Seljuk rulers (Qubād, Kay Khusraw and so on) and in the use of Persian as a literary language (Turkish must have been essentially a vehicle for everyday speech at this time). The process of Persianization accelerated in the thirteenth century with the presence in Konya of two of the most distinguished refugees fleeing before the Mongols, Bahā' al-Dīn Walad and his son Mawlānā Jalāl al-Dīn Rūmī, whose Mathnawī, composed in Konya, constitutes one of the crowning glories of classical Persian literature."
