The Most Noble Order of the Garter is a British order of chivalry. It is the world's oldest national order of knighthood in continuous existence and the pinnacle of the British honours system (after the Victoria Cross and George Cross). Its membership is extremely limited, consisting of the Sovereign, the Prince of Wales—both being members ex officio and gaining membership upon acceding to one of the titles if not already held—and not more than 24 full members known as Companions. Male members are known as Knights Companion, whilst female members are known as Ladies Companion. The Order can also include supernumerary members (members of the British royal family and foreign monarchs), known as "Royal" and "Stranger" Knights and Ladies (Companion), respectively. The Sovereign alone grants membership to the Order, meaning that ministerial advice is not sought.
