This year marks Prince Charles' 50th anniversary (!) as the Prince of Wales. His duties officially began after he participated in a ceremony called an investiture of the Prince of Wales, similar to the Queen's coronation, in 1969 at the Caernarfon Castle. Season three of The Crown will feature the ceremony Charles referred to as "very impressive," according to Town & Country. His mother, Prince Philip, Princess Anne, and Princess Margaret were all in attendance.
During the investiture, Prince Charles gave a speech in Welsh and English, beginning in Welsh and then switching to English. He reportedly studied Welsh at—you guessed it—the College of Wales to prepare for it.
"I hope and trust that in time I shall be able to offer my own contribution and to do that I seek your cooperation and understanding.
Speaking for myself, as a result of my two-month stay in this country, I have come to see far more in the title I hold than hitherto. I am more than grateful to the people of this Principality for making my brief stay so immensely worthwhile and for giving me such encouragement in the learning of the language.
I know that social conditions have changed since 50 years ago and, of course, are still changing. The demands on a Prince of Wales have altered, but I am determined to serve and to try as best I can to live up to those demands, whatever they might be in the rather uncertain future. One thing I am clear about and it is that Wales needs to look forward without forsaking the traditions and essential aspects of her past. The past can be just as much a stimulus to the future as anything else. By the affirmation of your loyalty today for which I express my gratitude, this will not simply be a faint hope."
Following the investiture, Charles noted: "For me, by far the most moving and meaningful moment came when I put my hands between Mummy’s and swore to be her liege man of life and limb and to live and die against all manner of folks—such magnificent medieval, appropriate words, even if they were never adhered to in those old days."
Spoilers for season 3. The Crown's depiction of Charles' time in Wales and the investiture is mostly true, although we can assume that the specific interactions are not. In the episode, Charles, who is happy and thriving at Cambridge University, is reluctant to spend a term in Wales—and when he gets there, finds many people there even more unfriendly than he had dreaded. But Charles noted later that his time in Wales had been transformative (he studied under Welsh nationalist Edward Millward, which even Millward described as a "surprising" choice, and the two developed a mutual respect for one another, which is shown in the episode), and Charles has remained attached to the country, making repeated visits and even buying land there in his later years.
You can listen to Charles' full speech here and watch season three of The Crown premiering on Netflix on November 17.
