Alexios I had a very hard time at the beginning of his reign as the Eastern Roman Emperor, having inherited an empire wrecked by years of civil war and the loss of Anatolia after the Battle of Manzikert. As if that weren't enough, he had to deal with the Normans who, one decade after conquering Constantinople's last stronghold in Italy, invaded the Balkans in 1081, scoring a devastating victory at the Battle of Dyrrhachium and overrunning much of Greece. The invaders were at last defeated at the Battle of Larissa, and the next decades were marked by a resurgence of Byzantine fortunes under the Komnenian restoration.
But what if the Normans scored yet another victory in Larissa, rather than being forced to retreat? Could they take over all of Greece, and from there capture Thessalonica and perhaps even Constantinople itself? Assuming the Queen of Cities falls under their rule, could they create a new empire, one stretching from Naples and Sicily to Bulgaria and the Bosphorous? Or would they be nothing more than a bigger version of the Latin Empire?
Lastly, would they call for a crusade, julst like Alexios did IOTL? My guess is almost certainly yes, given the Seljuk presence in Anatolia.
