A queen dowager has an important royal position (whether or not she is the mother of the reigning sovereign) but does not normally have any rights to succeed a king as monarch on his death unless she happens to be next in line to the throne (one possibility would be if the king and queen were also cousins and childless, the king had no other siblings, and she in her other position as his cousin was also his heiress presumptive).
Many former queens consort do not formally use the word "dowager" as part of their titles.
[citation needed] The Garter King of Arms's proclamation in the United Kingdom of the styles and titles of Queen Elizabeth The Queen Mother at her funeral on 9 April 2002 illustrates her dual status as a queen dowager and a queen mother: Thus it hath pleased Almighty God to take out of this transitory life unto His Divine Mercy the late Most High, Most Mighty and Most Excellent Princess Elizabeth, Queen Dowager and Queen Mother, Lady of the Most Noble Order of the Garter, Lady of the Most Ancient and Most Noble Order of the Thistle, Lady of the Imperial Order of the Crown of India, Grand Master and Dame Grand Cross of the Royal Victorian Order upon whom had been conferred the Royal Victorian Chain, Dame Grand Cross of the Most Excellent Order of the British Empire, Dame Grand Cross of the Most Venerable Order of the Hospital of St John, Relict of His Majesty King George the Sixth and Mother of Her Most Excellent Majesty Elizabeth The Second by the Grace of God of the United Kingdom of Great Britain and Northern Ireland and of her other Realms and Territories Queen, Head of the Commonwealth, Defender of the Faith, Sovereign of the Most Noble Order of the Garter, whom may God preserve and bless with long life, health and honour and all worldly happiness.A queen mother is a former queen, often a queen dowager, who is the mother of the current monarch.
Similarly, Adelaide of Saxe-Meiningen was queen dowager after her husband William IV was succeeded by his niece Victoria.
Similarly, whilst being the mothers of monarchs, both Augusta of Saxe-Gotha and Srinagarindra of Thailand were not styled queen dowager because their respective husbands, Frederick, Prince of Wales and Mahidol Adulyadej, Prince of Songkla, were never kings.
In the fantasy novel series A Song of Ice and Fire, and later the HBO series Game of Thrones, the character Cersei Lannister became the queen mother to King Joffrey Baratheon after her husband Robert Baratheon was killed in a hunting accident, although she managed to strong-arm the position of regent as well, and was thus known as the "queen regent".
In the 2023 Netflix series Queen Charlotte: A Bridgerton Story, actress Michelle Fairley portrays Augusta, Dowager Princess of Wales, King George's mother.
