The ATL I'm writing is mostly about events occuring in the greater part of the world. The Roman Republic is destroyed earlier, but I thought to keep the Hasmonean Kingdom of Judea around as it served a purpose. But its right between the Egyptian and Seleucid Empires, and its unlikely to survive as a fully independent state. But I figured that instead of simply wiping Judaism out, or allowing the development of "Rabbinic Judaism", I thought I'd allow the ancient clerical order to survive somewhere that won't meet the attention of their enemies. But before Jerusalem's society is destroyed, I'd like to buy time by having a decently wealthy and stable kingdom to the far south which is largely out of the way of Egypt and Syria (in poltical terms). I don't intend for their to be Christianity or an Islam in the TL I'm writing, and even Judaism might be overmatched in the Arabian Peninsula by Zoroastrianism, but I was thinking that within a couple of centuries, Judaism could have a tutelary influence over the internal development of Ethiopia or the Nubian kingdoms.
If there is a possibility that they would build a new Judaic Temple ten years, a hundred or two hundred years after the destruction of the old one, I don't know. But more important than the physical structure of the Temple itself is the Kohanim, its hereditary membership, its organisation, laws and rituals. This part about ancient Judea/Israel I'd like to get some advice about.
This alternate history of Judea-Judaism is small part of my Suebi Superpower TL.
