We’re probably not alone in feeling like history class is, well, ancient history at this point. While we enjoyed tales of social justice and exploration (and balked at tragic plagues and bloody wars), our brains haven’t really held on to many of the details. Fortunately, history memes have a way of reminding us of all those sentences we highlighted in our textbooks. They provide us with the feeling of being smart as we recall the strategies of Genghis Khan, or revel in the fact that there was even an ‘Emu War.» Best of all? They also make us laugh.
