World history tends to be kind of... dry. If you don't have much imagination, it just ends up being a big mass of dates and battles.
Too bad they don't show "Hetalia: Axis Powers - The Complete First Season" in schools, because it actually manages to present world history (particularly that of the World Wars) in a manner that is fun, quirky and downright bizarre ("I agree wis America." "ENOUGH or I'll beat you with my peace prize!"). And yes, most of the countries are represented by pretty young men.
Germany is searching through the woods for the descendent of the great Roman Empire... only to stumble across a naive, blubbering Italy hiding inside a tomato crate. He captures Italy, but is chagrined when Italy attaches himself like a limpet because "I get fed and nobody picks on me." They join forces with the very formal Japan, and the Axis Powers are born.
However, another alliance has appeared: the Allied Forces, made up of America, China, Russa, England and France. And as World Wars I/II rage, both sides must grapple with a cursed chair, England's bad cooking, supermarket lines, marriage proposals, being stranded on a deserted island, wok attacks, and cuckoo clocks... when they're not fighting one another.
Oh, and we get fun flashbacks to "Chibitalia's" childhood, when he was stalked by the Holy Roman Empire (uuuhh... baby Germany in a hat?), dragged into Austria's household, and ate churros.
"Hetalia Axis Powers - The Complete First Season" is one of those animes you shouldn't watch if you're easily offended. EVERYBODY in this show is a national stereotype who acts in a stereotypical way (ex: America is a bit arrogant and endearingly over-the-top, Japan is overly formal and can't pronounce Ls and Rs, Italy is obsessed with pasta, etc).
And it's all in good fun -- the stuff that goes on is based on real historical events, but filtered through a satirical anime/reality-show lens. The dialogue is gutsplittingly funny, peaking with Italy's song about Germany ("Even though I'm your prisoner, you give me food/and it doesn't suck like English food!"), and there's goofy slapstick and cultural references aplenty.
But there are also some more somber moments, such as America reminiscing about the War for Independence and his painful rift with England, or China thinking of how he found and raised Japan. And while all the characters are national stereotypes, the writers succeed in making each one endearing and likable... well, except maybe Russia. He's just creepy.
"Hetalia: Axis Powers - The Complete First Season" is very short (each episode is about five minutes long), but world history here has never been so cracktastic.
