The Bureau of the Royal Household announced that Thailand’s Princess Bajrakitiyabha Mahidol passed away peacefully at the age of 47 on Thursday evening, June 11, 2026. The eldest daughter of King Maha Vajiralongkorn had been receiving continuous medical care at King Chulalongkorn Memorial Hospital in Bangkok since falling unconscious in December 2022 due to a heart-related condition. According to royal officials, her medical condition gradually deteriorated following a recent severe abdominal infection that ultimately compromised several major organ systems.
Highly respected both domestically and internationally, the princess was an accomplished lawyer and diplomat who dedicated much of her life to advancing women’s rights and criminal justice reform. In response to the national tragedy, the Thai government has declared 15 days of official mourning and ordered flags to be flown at half-mast on all public buildings. Her passing leaves deep grief across the nation and introduces significant uncertainty regarding the formal line of succession for the Thai monarchy.
