A scimitar ( or ) is a single-edged sword with a convex curved blade associated with Middle Eastern, South Asian, or North African cultures. A European term, scimitar does not refer to one specific sword type, but an assortment of different Eastern curved swords inspired by types introduced to the Middle East by Central Asian ghilmans. These swords include the Persian shamshir (the origin of the word scimitar), the Arab saif, the Indian talwar, the North African nimcha, and the Turkish kilij. All such swords are originally derived from earlier curved swords developed in Turkic Central Asia (Turkestan). Etymology The English term scimitar is attested from the mid-16th century and derives from either the Middle French cimeterre (15th century) or from the Italian scimitarra. The ultimate source of these terms is corruptions of the Persian shamshir. Scimitar became used to describe all curved oriental blades, in contrast to the straight and double edged European swords of the time. The term saif in Arabic can refer to any Middle Eastern (or North African, South Asian) sword, straight or curved. Saif cognates with the ancient Greek xiphos, which may have been borrowed from a Semitic language, as both saif and xiphos go back to an old (Bronze Age) wanderwort of the eastern Mediterranean of unknown ultimate origin. Richard F. Burton derives both words from the Egyptian sfet. History of use The earliest evidence of scimitars is from the 9th century among soldiers in Khurasan. They were used in horse warfare because of their relatively light weight when compared to larger swords and their curved design, good for slashing opponents while riding on a horse. Nomadic horsemen learned from experience that a curved edge is better for cutting strikes because the arc of the blade matches that of the sweep of the rider's arm as they slash the target while galloping. Mongols, Rajputs and Sikhs used scimitars in warfare, among many other peoples. The scimitar was widespread throughout the Middle East from at least the Ottoman period until the age of smokeless powder firearms relegated swords to dress and ceremonial function. The Egyptian khopesh, brought to Egypt by the Hyksos, resembled scimitars. The khopesh is sometimes considered a scimitar. Early swords in Islamic lands were typically straight and double edged, following the tradition of the weapons used by the Islamic prophet Muhammad. Though the famous double edged sword, Zulfiqar wielded by Ali was
