When the crusaders battled against their Arab opponents, they came face to face with the deadly scimitar. The scimitar is a backsword with a curved blade that originated in the Middle East. It was used by warriors on horseback because it was lightweight in comparison to other swords, making it easy to wield while also holding the reins of a horse.
An early Crusader who had just arrived in the Holy Land viewed a band of Saracens from a distance. He was so impressed with the curved sword that they wielded that he attempted to locate his own. Naturally the Saracens were not anxious to trade with the enemy, so he was forced to use his own straight blade crusader sword. The image that the Crusader saw is the picture that the western world still holds of the Islamic warrior—a turbaned soldier with a curved blade sword.
