Yes, so does BG's Issac's Empire but that TL is actually plausible.
I know his is plausable but mine too is possible. Why can't their be a new relegion? Hmph Islam rose out of nothing, Christianity rose out of nothing it is not ASB. Assasins are not asb ever hear of the hashasheen Ringo? Varangians were in otl. In this tl like I will repeat Alexius wins at dyrachion okay Bohemund and guiscard die. That means their is no heir to inherit the apulia throne which throws apulia and calbria into chaos. The byzzies then get aid from Venezia an close ally of the byzzies. Ever heard of dominco and teodoras marriage? Thus Venice lent ships for specialtrade rights So under competant leadership Sicily fell
Anatolian conquest ok: in this tl te seijuk sultan dies!!! The seijuk empire was in a very unstable position. With the sultan dead it split apart into many factions. Said factions fought wars that destroyed themselves. Alexius took his time to reform te army and then Launch an invasion of Anatolia. He used divide an conquer to destroy the Seijuk successors. Is that so ASb. Next for jerusalum, then part ofthe fatamids, in this tl a massive war is fought
beetween the fatamids and seijuks successors leading to a seijuk jerusalum. However this splits off from the empire and the byzzies take he oppurtunity and sieze it. That is even less ASB than how a bunch of horse nomads brought down the most civilized empires of the world. Now I said Egypt was never
conquered. Next after alexius the emperors following were reformers and innovators. Not ASB. In otl John and Manuel were both very competant successors of Alexius. In this tl however with manpower base of Anatolia restored the byzzies launch the new found manpower and conquer Bulgaria. Bosnia and Serbia are still under Roman control. Next Crimea was still in byzziy hands.
So far none of this is asb is it ringo:?
Let's continue I recieved word that the empire was far too big, alrigh I split it into three states. The relegion of the god emperors rise is as ASB as the rise of christianity or Islam. It appealed to many people and found converts. In this tl the rus get attracted to this new relegion and it wins converts. When the mongols invade they too convert to this wonderful relegion. Thus it's rise is as ASB as the rise of other relegions so It is plausable.
Next the terror state, completly plausable because if you did not know Andronicos Komnenos was a guy whocreated suh a state in Byzantium.
Thus none of this is asb
So ringo tell me based of what you've read Which parts are ASB I would love to know.
I will just say this I am an avid researcher of roman history and the time period I am perfect with is the Komnenian restoration. I have read Alexiad, read various books In the komnenians their rise, etc, read books on crusades, watched manydocumentories they are my specialty. Thus I though this whole tl through. However sadly on this site not many know of the komnenian restoration or any tls on it. I agree BG wrote an excellent tl but this is a POD where Byzantium succeeds as a power after Manzikert It is too prove that Byzantium still had hope even after they lost at Manzikert.
Hope I answered your questions ringo.
