A knight banneret, sometimes known simply as banneret, was a Medieval knight ("a commoner of rank") who led a company of troops during time of war under his own banner (which was square-shaped, in contrast to the tapering standard or the pennon flown by the lower-ranking knights) and were eligible to bear supporters in English heraldry. The military rank of a knight banneret was higher than a knight bachelor (who fought under another's banner), but lower than an earl or duke; the word derives from the French banneret, from bannire, banner, elliptical for seigneur - or chevalier banneret, Medieval Latin banneretus.
