AHC: European "Islam"

Is there a way for a religion, Abrahamic, to be formed in the 600s-1000s, that, led by its founder, conquers territorys, and then continues on conquering after forming an empire?
 
Does the size and staying power of this religion matter? If you work on the lower end of the time frame you gave us, you could perhaps make a population in the outskirts of the Roman Empire or even somewhat outside it follow such a leader. If they can manage to conquer or enlist some of their neighbours, and then convince other people to join forces with them, they could end up conquering a bit. Maybe the same logic could apply to a small state closer to the Middle Ages. It has to be a population small enough to be dissatisfied with things as they are but large enough to be able to conquer stuff.

You'd have to be quite resourceful to make this work. By the times you mentioned, Christianity was already quite strong in Europe (especially the closer you get to the end of that time frame). A new Abrahamic sect would probably be regarded as similarly to a heresy, and most heresies at that time eventually died out even when they were initially successful. The religious context is just way different.

Could you move it back in time a little?

Too simple

The vikings return with Islam in their conquest of the middle east.
The Emir of Cordoba accept King John's vassalage in 1209.
The Mongols ransack Europe rather than the Middle East.
 
I don't reckon there are any independent centres of civilisation in Europe that could spur on barbarians into the outer circle of Roman possessions in the same way. There isn't the equivalent of Mecca built in distant Gaul or Germania.

I don't think the OP was asking for a scenario where Islam is more widespread in Europe but one where Europe gets yet another, probably fictional, Abrahamic religion.

Frige, you are right. Combine that with the fact that the political system within Roman borders and in some places outside of them was very different from the one in the Middle East, and also the fact that polytheism was not the dominant religious mindset anymore in much of Europe, and it's very difficult.
 
Your best bet is probably Arianism (denial of Jesus' divinity) becoming widespread in Europe. Perhaps Clovis decides to promote that way of thinking over Orthodox Christianity, demoting Jesus to a prophet and creating a new branch of the big happy Abrahamic family.

The roman religious system had just (well a relatively brief time ago) been overturned by Christianity, I highly doubt any new reiligion could have risen up with such vigor and success as Islam, though perhaps as one poster said Arianism could go along a different path and fill the role you are looking for.
