 With the installation of Emperor Alexander I of Russia in 1813 , supernumerary membership was extended to foreign monarchs , who are known as " Stranger Knights and Ladies of the Garter " . Each such installation originally required the enactment of a statute ; however , a 1954 statute authorises the regular admission of Stranger Knights or Ladies without further special enactments . In lesser orders of chivalry , such foreign members would be regarded as having received honorary knighthoods .
