Good article!  I got into a discussion about the Russian fur trade on another forum (we were discussing the Momoa series, Frontier) and I brought up several of the same points trying to explain to some people just how massive the fur trade was in both northern Eurasia and North America. That’s how Russia ended up colonizing Alaska and then finally selling it to the US. The fur trade was like the oil business now. BIG. Lots of $$$ and influence. Wars were literally fought over furs.
