• Princess Bajrakitiyabha, 47, died after nearly four years in a coma.
• She was known for her advocacy on women's rights and legal reforms.
• The princess's passing raises questions on the future of the Thai monarchy.
• Her funeral will be conducted with the highest honors according to royal tradition.

Princess Bajrakitiyabha Narendiradebyavati, the eldest daughter of Thailand's King Maha Vajiralongkorn, passed away on Thursday evening at King Chulalongkorn Memorial Hospital in Bangkok after spending nearly four years in a coma. Her health condition had deteriorated following her original hospitalization in December 2022 due to a severe heart condition and subsequent infections, including an abdominal infection that led to multiple organ failures, according to BBC and Channel News Asia.

Popularly known as Princess Bha, she was educated in law at Cornell University, earning both a master's and doctorate. Princess Bajrakitiyabha held various roles in public service, including as Thailand's ambassador to Austria and as a goodwill ambassador for the United Nations Office on Drugs and Crime. Her advocacy work particularly focused on improving the conditions for women in prison, highlighted by her establishment of the Kamlangjai ("Inspire") project, according to South China Morning Post and Al Jazeera.

The Thai royal family now faces significant questions regarding succession following her untimely death. Although the traditional custom in Thailand favors male heirs, a constitutional amendment allows females to ascend to the throne, which had led to speculation about her potential role in royal succession. Currently, her younger brother, Prince Dipangkorn, is considered the presumptive heir, according to India Times and Reuters.

The Prime Minister of Thailand expressed the nation’s grief, stating that the loss of Princess Bajrakitiyabha is "an immeasurable grief in the hearts of the entire nation" and highlighted her commitment to justice and equality as a lasting moral legacy. Her passing is mourned by many, with public tributes expected to take place, according to Bangkok Post and Le Monde.
