Because Hetalia has rekindled my love for history, I would like to show it to others, and maybe it could help others to be interested in that subject as well, which, in turn, can raise global awareness for cultures (in some people at least. Like me...I closely study the French now xPPP). I look forward to reading your suggestions!
(Also, Mods if this is not allowed...I am sorry, but please keep it here! But if it is really irritating and against every fiber of this community, it can be deleted)
Everybody who suggested things, thank you very much! It was a lot of help. My focus has changed a bit though. Instead of "Gaiz, watch Hetalia because it's hilarious", I will show accurate, funny, and unoffensive clips that would show the events we learned about in an anime-esque way. I would also mention that the anime/manga does have inaccuracies (to those who might be interested in continuing on to watching/reading Hetalia). And I will definitely show it to my teachers first (for approval). Again, thank you very much for helping me!
