Hi, Everyone.
In order to clarify my own ideas, I made a large scale (A1 paper size!) chronological chart. Click on the image below to get the PDF file:
In it, you will see a number of things:
- The ruler sequence of the Christian Khazar Empire (barely alluded to) which eventually invades and annexes the Kingdom of Saint Thomas
- A war between the Spartan Monks and the Empire of Jerusalem in the late XIIIth century (new idea).
- A full sequence of rulers for Thomasiene and the Empire of Jerusalem (some new names)
Finally, regarding the "disappearance" of the ERE, I think that the chart makes it clear that it does not really disappear in the late VIIth century but actually morphs into the Empire of Jerusalem. Basically here the scenario is the victory of Monophysitism within the ERE over the Chalcedonian Imperial Church (in our TL, as you know, it is the opposite). As a result, the ERE becomes even more "Eastern" but retains its official language (Greek) and its laws and institutions. The Arabs are integrated into its ruling class and become hellenized (like many Armenians were in our TL).
This is in the spirit of the "Is the Byzantine Empire the continuation of the Roman Empire" threads which have appeared of late ...
Let me know what you think.
