hey, all. in looking for new ideas for my ASB ATL, i read not too long ago that the Pinsk Marshes in eastern Europe have been so (relatively) impassible that they've formed a defensive border between Belarus and Ukraine for centuries. based on that, i decided that that particular border still exists in the ATL even as alot of others are changed, but even more recently i thought "Are there any other borders that would probably exist regardless of the TL?"
i figured this would be a good resource for everyone else, too, so here we are. does anyone know of any other such "conserved borders"? obviously the idea here is that it's borders that have existed for centuries if not millennia with few if any changes (off the top of my head, the basic geography of Iran might count, too) in contrast to the cliche of the Kazakh Border which anyone seriously going into alternate history knows shouldn't exist for anything with a POD earlier than about 1918 because of the extremely specific circumstances that resulted in it. for reasons which should be obvious, let's not bring up shoreline borders here.
