Princess Bajrakitiyabha Mahidol Dies at 47 Following Three-Year Coma
Princess Bajrakitiyabha Mahidol, the eldest daughter of Thailand’s King Vajiralongkorn, has died at age 47 after remaining in a coma for three years, according to an official announcement from the Thai Royal Palace. The Princess, a noted legal scholar and diplomat, passed away on Thursday evening following a long-term battle with an abdominal infection that had caused her health to decline steadily since 2022.
Who Was Princess Bajrakitiyabha?
Born on December 7, 1978, Princess Bajrakitiyabha was the only child from the first marriage of King Vajiralongkorn and Princess Soamsawali. Her professional life was defined by a commitment to law and international justice. According to reports from the BBC and AFP, she earned two postgraduate degrees from Cornell University in the United States.
Before her royal duties took center stage, she served in the Thai mission to the United Nations in New York and later worked within the Office of the Attorney General in Bangkok. Her international profile grew significantly between 2012 and 2014, when she served as Thailand’s ambassador to Austria and collaborated extensively with the United Nations Office on Drugs and Crime (UNODC).
Princess Bajrakitiyabha was a prominent advocate for the rights of incarcerated women. She frequently highlighted that Thailand held one of the highest numbers of female prisoners globally, often pushing for reforms in a justice system that frequently imposed harsh sentences for minor drug offenses.
Impact on Thai Royal Succession

The death of Princess Bajrakitiyabha creates significant uncertainty regarding the future of the Thai monarchy. Throughout her career, the Princess was viewed by many royalist supporters as a potential successor or a key regent to assist her younger brother, Prince Dipangkorn.
In 2021, King Vajiralongkorn elevated her to the rank of general and appointed her as chief of staff for his personal security detail. This high-level assignment fueled public speculation about her future role in the institution. Unlike traditional expectations for royal heirs, her background in international law and human rights advocacy made her a unique figure in the eyes of the public.
What Happens to the Funeral Arrangements?
The Royal Household Bureau confirmed that the Princess’s body will lie in state at the Grand Palace in Bangkok. Per official palace statements, the funeral proceedings will be conducted with the “highest honors” in accordance with long-standing royal traditions.
While the palace has not yet released a detailed timeline for the cremation or final burial rites, the transition period is expected to be marked by a period of mourning across the country. The death closes a chapter on a figure who was widely regarded as the most academically and professionally prepared member of the younger generation of the Thai royal family.
