Some of these memes may make you feel like nothing is sacred, but they're all in good fun. While we realize that some of the periods that are tackled in these pics were exceptionally bleak, learning about horrific events and acknowledging them is an important part of healing. Keeping history alive and having fun while doing it ain't a crime. After all, history memes are way more fun than when we were learning this crap in school.

It's big brain time.

Beats class.
