Modern historians have essentially fallen into two camps on the issue. The first camp essentially agrees with Gibbon, and the other argues that the Battle has been massively overstated – turned from a raid in force to an invasion, and from a mere annoyance to the Caliph to a shattering defeat that helped end the Islamic Expansion Era. It is essential, however, to note that within the first group, those who agree the Battle was of macrohistorical importance, there are a number of historians who take a more moderate and nuanced view of the significance of the battle, in contrast to the more dramatic and rhetorical approach of Gibbon. The best example of this school is William E. Watson, who does believe the battle has such importance, as will be discussed below, but analyzes it militarily, culturally, and politically, rather than seeing it as a classic "Muslim versus Christian" confrontation.
