This timeline is basically the same as the one below, but owing to some research and discussion since the original thread was posted, it is being restarted.
Credit goes to the same people as originally. Were it not for their work, this timeline would remain merely a vague dream of a world with a surviving Byzantine Empire. As before, Latin spellings are normal, though the author reserves the right to be inconsistent. The term "Byzantine"/Roman/Rhomanian all refer to the same empire (except when it is obviously that the Holy Roman Empire and its supporters are referring to their state as Roman).
The POD is in 1166, when a son is born to Manuel Comnenus. Despite this, nothing much changes until 1176, when Manuel in an uncharacteristic moment of caution, accepts the Seljuk Sultan's offer of part of Turkish Anatolia in exchange for a ten year truce between the Empire and the Sultanate.
Chapter 1 begins seven years into this truce, with the ascension of Alexius II.
