@ArishMell They went to England and Wales, known as Britannia. We are talking about 3000 miles of conquered land in Europe, Middle East, and North Africa. The roads make it many more miles. Mongols were a world power also. Power and superpower is splitting hairs. At the time, the Roman Empire was as big as you get. It was then the Mongols, and the Spaniards.

I am not splitting hairs. None of those were world powers, a concept that arose only after WW2 with the USSR, USA and now China able to exert influence far more internationally than even the Romans, Spanish and British Empires managed.
