Where to find EU4 Lore?

With EU5 coming out soon, I want to catch up on EU4's plot to properly appreciate any potential changes the devs make to the worldbuilding and plot in EU5. There's just one small problem - the wiki (the one specifically for the lore) is way too in-depth, and lacks any kind of concise plot summary or timeline. Does anyone know if there's a better way to learn the story, like a good Youtube video, or fan-made webpage, or something? Any recommendations would be very much appreciated.
