The Most Noble Order of the Garter represents the highest level of English chivalry, established as a fraternal society for the Sovereign and twenty-five Companion Knights. Rooted in the ideals of Arthurian legend and the crusading spirit, it was designed to bind the nobility to the Crown through a shared code of honor and martial loyalty. The Order's spiritual home is St George's Chapel, Windsor Castle, where the heraldic achievements of each member—including their banner, crest, sword, and enameled stall plate—are displayed in perpetuity within their assigned choir stalls.
Membership is granted solely at the discretion of the Sovereign and remains one of the few honors that is not bestowed on ministerial advice. The ceremonial regalia is steeped in heraldic tradition, featuring the iconic blue velvet mantle, the collar of gold Tudor roses, and the 'Great George' pendant. Historically, the Order served as a vital tool of medieval diplomacy and royal patronage, evolving from a band of military companions into a prestigious institution that marks distinguished public service and loyalty to the British state.
