Don’t forget the unsuccessful Arab sieges of Constantinople in AD 683 and 717 that were probably just as decisive as the Battle of Tours, if not more so, in keeping the Arabs out of Europe.
I’d argue more so. Not to minimize the importance of Tours, but the threat from the East was much more dire. If Constantinople had fallen, Eastern and much of Central Europe would’ve lain wide open for muslim conquest. Furthermore, it’d do away with the only significant Christian naval presence in the Mediterranean.
However, I see both as very important bookend victories which limited muslim gains in Europe and dashed their aura of invincibility.
