Genghis Khan, for one (6)
I believe the answer is:
mongol
'genghis khan for one' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mongol that I've seen before include "Member of Genghis Khan's clan" , "Oriental" , "Asian" , "eg Genghis Khan" , "Native of country bordering China" .)
