A slightly more successful Conradin who fails to retain Germany could see a Hohenstaufen (Altastaufer, Ghibelino, or Svevi?) Sicilian Empire versus Imperial German Kings both claiming Italy and the Imperial title.I think the easiest way to do this would be to have Henry VI avoid his assassination, thus allowing the Hohenstaufen to divide between Germany and Sicily. Eventually when the northern dynasty dies out (and assuming that this division of resources allows them to crush the Pope and the Italian city states) the Sicilian branch manages to press their claim to Italy (and stop the new German king from crossing the Alps) but fail to keep Germany itself. Say that this branch has land in the North (Spoleto, Milan, Provence) inherited/exercised as imperial vicars or medieval Habsburgs or the like.
This isn't especially easy bit it's not impossible IMHO, if one give the Hohenstaufens a century or so to consolidate royal power. This also has the benefit of seeing the communes decline and be replaced by the strongmen.
I would point out that Norman Sicily, if it can be free of italian/German entanglements, is exceedingly likely to get involved in Greece, hell I could even see Frederick II claiming the Latin Empire by right of conquest and given his attitude towards native muslims I think he could win enough support to make it stick while he's alive. Add to that Tunisia (he is after all grandson of Roger II the man who conquered Africa), and whatever he can gain from the Crusades, Reconquista, marriage deals (say inheriting Provence in place of the Anjou) thats quite a mediterranean empire.
What were the ongoing entanglements of Manfred in Greece?
This was already discussed in another thread some months ago, IIRC.Turns out Manfred was allied to Despotate of Epirus through marriage to Helena Doukaina.
So if Manfred wins at Benevento in 1266, what are the butterflies in Greece?
So take a PoD where there IS the Anjou invasion, and Benevento, but Manfred wins.This was already discussed in another thread some months ago, IIRC.
The bride chosen by Manfred makes sense only if he had already in mind a scenario where he would not context central and northern Italy as the Hohenstaufen champion,but rather would reach an agreement with the pope (which would have been quite possible between say 1258 and 1263) and consolidate his hold on the kingdom of Sicily before looking for glory and lands in Greece. Under such hypothesis, there would be no Anjou invasion (the king of France was not even in favour of it), and obviously no Benevento.
Taking your POD, Manfred is still ruling the kingdom of Sicily (although he has not been anointed by the Pope). Depending on how Benevento battle develops, he may or may not have suffered high losses (high losses would still weaken his position and possibly result in additional plots and/or outright rebellions of the barons). Even in the best possible outcome, Benevento would not be a decisive victory: he'll be forced to remain near the border with the Patrimonium Petri, his influence in Rome has already been frittered away (he never managed to become Senator as I already said) and it is quite likely the Anjou will be back for a second round, this time with some real support from the king of France. Ten years before Benevento he might have been able to unite the Hohenstaufen partisans in northern Italy as the heir of Frederick II, but by 1266 any good will has certainly evaporated.So take a PoD where there IS the Anjou invasion, and Benevento, but Manfred wins.
What happens next in Italy? How is papacy and Guelfs in Northern Italy affected in 1266 if Charles is killed and Manfred victorious?
Charles won´t be back as per PoD, which is that he´s dead at Benevento battlefield.Taking your POD, Manfred is still ruling the kingdom of Sicily (although he has not been anointed by the Pope).

What did Guelfs do OTL in 1268?I would assume that the situation in northern Italy will not be different, and possibly the pope will try to set up a Mark II Lombard League which might make very difficult for Conrad the Younger to ride toward Rome.
The obvious claimant would be Charles II, who is still underage. If Louis of France listens to the pope, there may be another expedition in a couple of years time (Charles would be 14, and according to French succession laws should be of age).Charles won´t be back as per PoD, which is that he´s dead at Benevento battlefield.
Does Pope (Clement IV) have another claimant ready up his sleeve? If yes, who?
What did Guelfs do OTL in 1268?
And how would the 1266 campaign go after Benevento? Charles is dead as per PoD, but Clement lives, and Guelfs of Northern Italy are still around.
But Charles I does not have any legitimate claim. He´s pulled out of Pope´s ass - Popes had proposed Richard of Cromwall and Edmund of Lancaster before and after Charles I.The obvious claimant would be Charles II, who is still underage.

OTL, there was no outside Ghibelline army in Northern Italy from early 1266 (Manfred crushed) till mid-1267 (Conradin crosses Alps). TTL, Manfred, having crushed Charles, may go on offence into Central and Northern Italy in 1266-1267. But what could he accomplish?Other than that I don't expect that the situation in northern Italy would substantially differ, although the separation between Guelfs and Ghibellines was always a bit blurred
Why should Charles lack a legitimate claim to the kingdom of Sicily?But Charles I does not have any legitimate claim. He´s pulled out of Pope´s ass - Popes had proposed Richard of Cromwall and Edmund of Lancaster before and after Charles I.
With Charles of Anjou dead at Benevento, the 11 year old Charles the Lame is heir to failed attempt to usurpation alone. While 13 year old Conradin in Germany has much more Staufen legitimacy. And Manfred is the adult winner at the field.
