A scimitar 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 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).
