Trying reading here one might bear in mind that non Persian dynasties such as the Ghaznavids Saljuqs and Ilkhanids were rapidly to adopt the Persian language and have their origins traced back to the ancient kings of Persia rather than to Turkish heroes or Muslim saints Turcoman armies coming from the East had driven the Byzantines out of much of Asia Minor and established the Persianized sultanate of the Seljuks renewed the Seljuk attempt to found a great Turko Persian empire in eastern Iran It is to be noted that the Seljuks those Turkomans who became sultans of Persia did not Turkify Persia no doubt because they did not wish to do so 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 FYI historychannel is not a published source
