Wikipedia warnings to be assumed:
http://en.wikipedia.org/wiki/ScimitarA scimitar (/ˈsɪmɨtər/ or /ˈsɪmɨtɑr/)[1] is a backsword or sabre with a curved blade, originating in Southwest Asia (Middle East).
The curved sword or "scimitar" was widespread throughout the Muslim world from at least the Ottoman period (but a lot of similar swords like Zulfikar, al-Mikhdham, al-Qadib... etc. were already used by Arabs[citation needed]), with early examples dating to Abbasid era (9th century) Khurasan.[2][verification needed] The type harks back to the makhaira type of antiquity, but the Arabic term saif is a loan from Greek xiphos[verification needed] (the straight, double-edged sword of Greek antiquity). The Persian sword now called "shamshir" appears by the 12th century and was popularized in Persia by the early 16th century, and had "relatives" in Turkey (the kilij), the Mughal Empire (the talwar).
