Queen Elizabeth has appointed Camilla, Duchess of Cornwall to the Order of the Garter.
On Friday night, the Queen announced that the Duchess of Cornwall would become a Royal Lady of the Order of the Garter.
Additionally, Baroness Valerie Ann Amos was declared to be a Lady Companion, and former Prime Minister Tony Blair was given the title of Knight Companion of the Most Noble Order of the Garter.
The Order of the Garter was founded by Edward III in 1348 and is the most senior order of knighthood in the British honors system. The number of companions is limited to 24, although supernumerary members do not count towards this total.
The Order includes the Queen, who is Sovereign of the Garter, several senior members of the royal family, and 24 knights chosen in recognition of their work. Knights of the Garter are chosen personally by the monarch to honor those who have held public office, contributed to national life or personally served the monarch.
Other members of the Order include Prince William, who was made a Knight in what is the most senior order of chivalry in the U.K. in 2008, as well as Prince Charles.
Sir Winston Churchill and Prince Philip were also bestowed with the honor in their lifetimes.
A grand procession of the knights takes place at Windsor Castle every June, accompanied by a marching band and Officers of the Order, all in grand ceremonial dress. Hosted by Queen Elizabeth, the Order of the Garter ceremony is one of the grand high points in the royal calendar.
