He would later establish the Seljuq Sultanate after conquering Persia and retaking the Abbasid capital of Baghdad from the Buyid dynasty in 1055. Tughril relegated the Abbasid Caliphs to state figureheads and took command of the caliphate's armies in military offensives against the Byzantine Empire and the Fatimid Caliphate in an effort to expand his empire's borders and unite the Islamic world.  - Middle Persian is the Middle Iranian language or ethnolect of southwestern Iran that during the Sasanian Empire (224654) became a prestige dialect and so came to be spoken in other regions of the empire as well.

Banished from the capital, Baghdad, earlier, he was now recalled and appointed to the office he had long desired. He held the Caliphate for 40 years. It was during his Caliphate that Mahmud of Ghazni arose, threatening the empire; and but for the conflicts that broke out in Mahmud's family upon his death, the Buwayhid kingdom, paralysed by damaging war, would have been swallowed.
