How about giving your dad a subscription to a history magazine like National Geographic History, which covers a wide range of historical events from around the world? Another great gift idea could be a book about a specific period or event in world history that your dad is interested in, such as "The Rise and Fall of the Third Reich" by William Shirer or "Guns, Germs, and Steel" by Jared Diamond. You could also consider tickets to a historical tour or exhibit in your area or even a replica of an artifact from a museum or a period piece, like a sword or chess set.
Or you can get him a star map with an important date you share.
