King Charles III ascended to the throne on May 6th, coinciding with Archie's fourth birthday. Prince Harry and Meghan Markle declined the invitation to attend the coronation ceremony in London, choosing instead to celebrate their son's birthday in California. During a private family gathering, King Charles raised a toast to Archie, wishing him a happy birthday and acknowledging those who were absent.
Harry left immediately after the coronation to be with his son and arrived in time to tuck him into bed personally. The celebration was reportedly low-key, featuring a homemade lemon cake, and attended by only the closest members of the family. On social media, a photograph was shared of baby Archie touching a picture of his grandmother, Princess Diana.
