How about a chronological history book of the world or maybe a globe that lights up with the names of the world's countries and their historical timeline? You could also give him a subscription to a history magazine or take him on a trip to historical places that he's always wanted to see. Another idea could be a personalized map of the world with pins to mark his favorite historical events or even a custom-made historical themed board game.
Or you can get him a star map with an important date you share.
