On April 16, 2026, Queen Margrethe of Denmark celebrated her 86th birthday with an intimate concert at Fredensborg Palace, attended by several members of the royal family, including her daughter-in-law, Queen Mary. This event marked a significant occasion, as it was Queen Mary’s first public appearance following the recent death of her father, Professor John Dalgleish Donaldson.

Accompanying the birthday celebrations were King Frederik, Queen Anne-Marie of Greece, and Queen Margrethe’s beloved dachshund, Tilia. The event was intended to be a joyful gathering, but it was not without its share of memorable moments, including a slightly awkward exchange between the two queens.
As captured in footage shared by Hello! magazine, Tilia, the dachshund, trotted up the staircase to join the royal party. When the dog approached Queen Mary, she instinctively reached down to pet Tilia. However, Queen Margrethe interjected, stating, “I don’t think this is the right time for that.” This quick correction caused Queen Mary to retract her hand, and Tilia subsequently followed the royal family back inside the palace.

Queen Margrethe, who abdicated in January 2024 but retained her title, continues to play an active role within royal engagements. Her firm yet light-hearted remark to Queen Mary did not overshadow the day’s celebrations but rather added a humorous highlight to the event. The exchange underscores the dynamics within the royal family, particularly regarding roles and expectations.
Queen Mary, aged 54, demonstrated a thoughtful balance in her choice of attire for the occasion. She wore a navy suit, a selection that allowed her to honour her father’s memory while participating in the festivities for Queen Margrethe. Traditionally, black is worn in mourning, but Queen Mary’s dark attire could be interpreted as a respectful nod to her recent loss, while still celebrating the occasion at hand.
Just days before the birthday celebration, on April 12, the Danish Royal House announced the passing of Queen Mary’s father at the age of 84 in Australia. His health had been deteriorating for several years, and the palace confirmed that Queen Mary had spent quality time with him during her last visit in late March. A private memorial service is expected to be held in his honour.
In her first public engagement since this personal loss, Queen Mary’s participation in Queen Margrethe’s birthday highlighted her commitment to the royal family and their traditions. Despite the poignant backdrop of mourning, the event remained a festive affair, showcasing the bonds of family and the continuity of royal duties.
Notably, Queen Mary shares a fondness for dogs; at home, she has two border collies named Grace and Coco. Her love for animals, coupled with the brief interaction with Tilia, only served to underline her gentle nature, even in a potentially uncomfortable situation. The incident, while slightly embarrassing, speaks to the candidness often found within royal circles, revealing a more relatable glimpse into their lives.
In summary, the celebration of Queen Margrethe’s 86th birthday served as a poignant reminder of both joy and sorrow within the Danish royal family. As they navigated personal and public duties, the event illustrated the complexities of royal life, filled with moments of affection, correction, and resilience amidst changing times.
