worldbuilding

Yeah, it's a lot of fun to think about how people being extremely long-lived or immortal would shape a society. Just off the top of my head, you can't really disentangle human political development from the idea of inheritance, whether that be inheritance of property or the countless societies that have had some form of hereditary rule.

I'd be interested in hearing how you apply Historical Materialist thinking to world building.

Thanks for asking! To give one example, my most recent project has been a bronze-age society of sapient gryphons (who have the talon dexterity to use tools and do other human things). Having just come off reading David Graeber's Debt: The First 5000 Years, I remembered a section describing how currencies like metal coins in many cases ended up being marked and used as forms of credit ledgers, and reading about how during food shortages, ancient states would often do some form of grain distribution to stave off the worst of famine.

From these, I came up with the idea of a sort of welfare system where, during times of famine, the gryphon society's state issues monthly tin coins, each entitling a citizen to a share of millet from the palace granaries. The first three times the coin is redeemed, it's punched, and the fourth and final time, the coin itself is turned in, to be melted down and recast for next month's distribution. In effect, the coins act as a sort of bronze age ration cards. Tin was chosen for its low melting point (handy to use for things you're repeatedly recasting) and because I'd earlier established that the society was known for its expert bronzeworking, implying that it had access to appreciable tin deposits.
