Dry your tears, Ryan! Fur is important and absolutely belongs in any history we tell of Siberia. It’s just not the whole story. To me, this is epitomized visually in the 4-panel illustration of the Russian embassy to the Holy Roman Emperor in 1576. We all know the image: the Russian entourage with men bearing finely assembled forties of sables and other furs. It appears on the cover of one book, in texts, etc.
If you’ll make allowances for my admittedly myopic perspective, I’d say that to the extent that there are iconic images for early Russian history, this is among them. But, the whole image actually consists of 4 panels.
After the diplomats and men bearing furs occupy panels 1 and 2, panel 3 continues the entourage with men bearing textiles. So, panels 2 and 3 are in the book (pp. 86–7), to help visually make the point that fur is an important part of the story, but there’s more that mattered, and becomes readily apparent just as soon as we keep looking.
To switch gears somewhat: however unattainable exact figures may be for what proportion of Russian revenue fur occupied, I think it’s safe to say and interesting to consider that fur never held nearly the importance in Russia’s economy that oil and gas hold today (oil/gas revenue accounts for around 70% of Russia’s export revenue and oil and about half of the Russian budget).
Since you mentioned chapter 4–I’m glad you liked it–let me chime in on the process for that one. As I drew to a close writing the chapter explaining the Siberian customs administration (chapter 3), I found I had all this material that wouldn’t make it in. I figured I would just sit down and write it up, string it together so I could at least have a collected look at all that wasn’t going in before I put it to rest; it was literally, going to be my way of saying goodbye to this material. As I did this, it became clear that there could be “space” for it after all. Interestingly, this chapter was the easiest to write (which may say something about the advantages of starting with little expectations?). As you point out, there is just so much more we’d all love to know about how corruption fits into the picture . . .
