Without Turko-Persian culture, Seljuk architecture does not get transmitted to India(Architecture of Mughal India, Part 1, Volume 4, by Catherine Blanshard Asher, page 10;Central Asia in World History, by Peter B. Golden, page 107). If the Seljuq Empire was not Turko-Persian in culture, how does the Sultanate of Rum have Persian as it's lingua franca?(Grousset, Rene, The Empire of the Steppes: A History of Central Asia, (Rutgers University Press, 2002), 157) Instead of seeing race and ethnicity in the word Turko-Persian, you should see how Turks(Seljuqs, Ghaznavids) used a language and culture, built empires, spreading their art and architecture; through that language. The Seljuqs and Ghaznavids contributed just as much into the Turko-Persian culture as they got out, hell even more so!
