Every Ruler in Europe Every Year Since 400 BC
Really well done! Though for me this also underlines how ambiguous terms like "ruler" can be. For example, at the very end, it shows "Willem Alexander" as the "ruler" of the Netherlands. He's the ceremonial king with virtually no political power. Yet, Germany is shown to be ruled by Angela Merkel, the political leader of the federal government. Yet, despite not being a monarchy, Germany has a person with a role very similar to Willem-Alexander: President Steinmeier. Unless you're German, you have probably never heard of him, for good reason. The video should've probably either replaced Merkel with Steinmeier, or Willem-Alexander with the Merkel of the Netherlands, Mark Rutte.<p>This is not to nitpick on this excellent video: it's to illustrate how hard to is to explain, analyze and visualize history. This stuff is nuanced! Pick any random date in the past in this video, and there may well be something similarly "wrong-ish-but-not-entirely" somewhere on there.
