This video talks about how leftist bias in academia distorts people’s perception of the Battle of Tours.  From the video page: “The importance of the battle at Tours in 732 A.D. is nowadays downplayed by many historians.  According to them, Abdul Rahman’s invasion wasn’t really dangerous for Europe: either because it was merely an unimportant episode during the wars of European nobles against each other, or because it was only a ‘raid’ - a temporary incursion - , or because Muslim expansion had already ‘lost its momentum’ by the time of Tours, anyway.  This video describes the battle and counters these views downplaying the battle’s significance.”
