here’s some things I’ve gotten really into at times! very fun self-guided studies according to me at least: - Arctic and Antarctic age of exploration expeditions - conservation of wild / native bees - Irish medieval literature - history of English script and how to read different hands - wetland ecology and (related) uses of bogs by Iron Age European cultures - Red River and Northwest rebellions
aware that these might be more specific than you’re looking for but also: - American murder ballad traditions as a precursor to modern true crime - history of beading + how it was impacted by colonialism - Shetland knitting traditions (Shetland lace and Fair Isle stranded colorwork) - Catharism and the Albigensian crusade - anatomy + ecology of aquatic macroinvertebrates - songs from the Diggers / True Levellers
