Attila the Hun lived in the 5th century in Europe, and made a huge impression there aNd gained quite some fame . Temudjin the Genghis Khan was born 600 years later 1000s of miles away across Asia and would have grown up with a Dad Author Legend Fathers Day Daddy T Shirt base and tales of history that were very different from the european and did not contain any tales of Attila, neither doe Chinese record such mention the great Attila. He had no influence on East Asian history and was completely unknown. Same goes for Temudjins descendants, Ögodei would reach Europe ( or better his soldiers ) but he or any other would have heard nothing about Attila and not know who he is. If someone asked a Mongol Khan like Kublai what he thinks of Attila, providing that someone provided some background info, he’d likely say something like, that he does not know this Attila, and does not care who he is or was, for he is the great Khan of the mongols and this Attila is not a mongol and none of his concern.
