Limiting this to channels that aren't about current events, which seem to still be uploading, and which I am confident of the location of. All work primarily in English

• Adam Millard - UK, videogame design
• Alexander the ok - UK, engineering oddities (usually in the second half of the 20th century)
• Andre Antunes - Portugal, makes metal music out of unexpected videos
• Cambrian Chronicles - UK, ancient Welsh history (also his "anything else" second channel, Cadwaladr)
• Chris Spargo - UK, basically the exact same idea as Tom Scott's "I'm in random place" videos
• f4mi - Italy, retro tech
• Foil, Arms, and Hogg - Ireland, comedy sketches
• Fredda - Norway, political history
• J Draper - UK, London history
• Jazz Emu - UK, comedy music
• Joseph Newton - UK, maths oddities
• Khanlusa - UK, videogames
• Lemmino - Sweden, the kind of history mysteries that people make conspiracy theories about
• Let's Talk Religion - Sweden, comparative religion with a focus on Islam
• Map Men - UK, geography oddities
• MQTate - Isle of Man, chemistry oddities
• Napoleon Blownapart - Ireland, MMA. I do not care about MMA at all, Napoleon is just so goddamn funny
• Paul Davids - Netherlands, guitar
• People Make Games - UK, videogames
• Squidge Rugby - UK, rugby

I guess somehow almost none of the film channels or women in my subscriptions are European? Huh
