Among the guests were Queen Camilla, who became Colonel of the Grenadier Guards in December, the Prince of Wales, who assumed the role of Colonel of the Welsh Guards from his father after King Charles's ascension to the throne, and the Princess of Wales, who took over as Colonel of the Irish Guards from her husband.
The Duke of Edinburgh and the Duke of Kent also attended the dinner due to their appointments as Royal Honorary Colonels of the First Battalion London Guards and the Scots Guards, respectively.
However, across the Atlantic, the Sussexes were not invited to join the family celebration. They did not receive an official invitation to the annual Trooping the Colour event, which is a public celebration of the British monarchy's birthday.
This event has a long history dating back to the 1600s and involves a parade with hundreds of British troops. The Royal Air Force also stages a special fly-past. Christopher Anderson, author of "The King," remarked that Harry would not attend just to be humiliated once again.
According to Angela Levin, a royal biographer, Harry's recent verbal blunders, including his testimony in the hacking case against Mirror Group Newspapers, have diminished his worthiness of his family's regard and his royal status.
She expressed hope that King Charles would take action after the court case, as she was incensed by Harry's statements about the United Kingdom. Harry has a history of blaming the world for his own problems, with his memoir "Spare" being a prime example of his outspokenness.
Levin believes that Charles has reached his limit with Harry and his behavior, despite being fifth in line to the throne. She stated that Charles has endured the disrespect thrown at him regarding Camilla, William, and others, but he will not tolerate Harry continuing to behave in such a manner in the country.
