I started this one in the early 2nd millennium BC, and I have worked so far up to early medieval history. Going this far back has put new emphasis on Persian peoples as a division of Middle Eastern peoples, and on Balkan peoples in Western Civilization. Persia proper, or Iran, will start to get better connected: I don’t yet have specifics much further back than the 1979 Iranian revolution, but this will definitely fill out some big gaps in Middle Eastern history. I have long been wanting to get Latin peoples back as far as the Roman empire, and that’s finally happening. Getting more of Germanic peoples back through medieval times will also be helpful.
