On 23rd December 1947 came the welcome announcement of the appointment of His Majesty, King Frederick IX of Denmark as Colonel-in-Chief of The Buffs, in succession to his father. Following in his father’s footsteps, King Frederick maintained a very close relationship with the Regiment. On Wednesday March 1st, 1961, The Buffs (Royal East Kent Regiment) were amalgamated with The Queen’s Own Royal West Kent Regiment to form 1st Battalion The Queen’s Own Buffs (The Royal Kent Regiment). King Frederick was appointed Colonel-in-Chief of the new regiment.
Just under six years later the Regiment changed its identity once again and became The Queen’s Regiment and King Frederick retained the title of Allied Colonel-in-Chief of The Queen’s Regiment (Queen’s Own Buffs). King Frederick IX died in 1972 and was succeeded to the throne by his daughter Queen Margrethe II who was appointed as Allied Colonel-in-Chief of the Regiment in the same year.
In September 1992 further amalgamations were deemed necessary and The Queen’s Regiment were joined by The Royal Hampshire Regiment to form The Princess of Wales’s Royal Regiment. Queen Margrethe was appointed Allied Colonel-in-Chief. In February 1997, following the resignation of Diana, Princess of Wales as Colonel-in-Chief, HM Queen Margrethe II assumed that appointment.
