Wait, the monarchy wasn't always just a way to keep tabloid photographers employed?

As Americans, it is our birthright to be uninformed about the British crown. All you have to know is we kicked them out, some other stuff happened for 240 years, and now they're our aging lapdog. If you insist on actually learning about America's jolly old mom-country, however, you could do far worse than the videos of YouTube explainer CGP Grey. Today's video, in honor of Lizzie the Second unlocking the achievement of longest-reigning British monarch (and longest-reigning queen in world history), rewinds the clock on the story of the UK's kings and queens over the past 951 years, which will make you seem pretty smart if you remember any of it.
