Was the battle of Yarmouk actually caused the Byzantine Empire to lose Syria (and subsequently all the levant and the North Africa), or would it have happened inevitably even if the Byzantines won the battle?
Ok, I want to hear from the both sides of this argument. I have heard some say that Yarmouk was a decisive moment in history of the Byzantine Empire (like Manzikert), while others argue that a Byzantine victory would not have stopped the tide of Arab conquests in the long term. Which view do you think is more likely?
