Tirkic is not essential and does not need to be mentioned at all It is not natural to occur in the lead I repeat for I don t know how many times that we don t say Slavic Bulgarians in any lead Reasons for not including the Danube Bulgar Khanate and putting it in a footnote as Constantine suggested 1 Does not apply for the whole existence of the state 2 It is completely out of context there it is used to differentiate it from Volga Bulgaria 3 Not the only name used for that period also we use Danube Bulgaria Bulgarian Khanate and others PS I am not going to be home until Monday so don t modify the article itself until I return to resolve the last details
