Seriously did you just quote a title from a general history book? Dubious to say the least. Wouldn't you rather have the article more detailed in describing the state? Persianate state, Seljuk Turkic-ruled. You have one line which describes the Sultanate of Rum in more precision than you quoting off a title from a general history book that's not even specialized with the detailed history of Seljuks in the first place. But that's not the major dispute so let's not even pretend this is what the argument's about. Secondly, back to the Persianate source, your point is still invalid. The culture of the Great Seljuq court was adopted by the Sultanate, therefore the Sultanate had the same court system. I cannot believe you're actually contesting this, since there are plenty of sources which describe the Persianate identity of the Seljuks as a WHOLE, be they Great Seljuks or Rumi Sultanates. And to further prove this point is the fact you have them adopting Persian officially and courtly. Sorry but your edits were weird to say the least, because you moved a source unrelated to arts and architecture to that respective section, probably for the reason of disguising facts. Listen man, what happened a thousand years ago cannot be changed. Moving things around on wikipedia isn't going to change what happened I'm afraid.
