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.
Soldiers of the Khurasan region of Persia are the first known users of the scimitar during the 9th century. During the crusades, a special crusader shield was designed specifically to protect the wearer against the deadly scimitar. Today, the weapon still holds significance. For instance, it can be seen on the coat of arms of Saudi Arabia.
