Robert IV Of France

Just a quick one, what if Philip IV's fourth son Robert had not died in 1307, but lived on into adulthood? WOuld he have married his intended Constance of Sicily? If so what would this have brought his father?

Would he have come to the throne following his brothers, and could this have prevented the hundred years war, or started another war with England over Gascony
 
WOuld he have married his intended Constance of Sicily?
I don't see why not, if Frederic holds by the Caltabellotta Peace. That said, the risk of having this one being broken is still important, and I'm not sure the project of union would last giving Bonifacius was dead.

If so what would this have brought his father?
I'm not sure to understand. You mean the political reason? Well, Angevines were Capetians, and depended a bit (for their mediterranean policies) of the elder Capetians support.

This union could have cemented a bit more the Treaty of Caltabellotta, meaning a possible lasting peace if not Sicily turning back to Angevines according the treaty's clauses.

(It could have well been a pressure on Charles II, giving his support for Bonifacius at this time, but I don't find a year for this union project).

Would he have come to the throne following his brothers
If they still die ITTL, probably.

and could this have prevented the hundred years war
As such, probably. But tensions grew enough and the Capetian/Plantagenet conflicts were already an established situation at this point. So, you'd probably end sooner or later with another war, which may be harsher than the precedents.

or started another war with England over Gascony
Maybe. It would probably follow the "Plantagenets kings are bad vassals, many of their own vassals complain to me, their ultimate suzerain. As he doesn't wants to humiliate himself, I've confiscate Gascony and go to war against him. What a shame."

Fair play interesting as well would this make for an interesting timeline?

Still not sure how Robert surviving could prevent the deaths of his brothers?
