Childhood & Early Life
Her Royal Highness Ubolratana Rajakanya was born on April 5, 1951 in Clinique de Montchoisi, Lausanne, Switzerland to Bhumibol Adulyadej and Sirikit. Her father, King Bhumbibol, was the ninth monarch of Thailand belonging to the Chakri dynasty and was conferred the title of Rama IX.
Rajakanya was partly named in honor of her maternal grandmother, and her name means ‘glass lotus’. She is fondly referred to as Pay by her parents and Phi Ying by her family. The people of Thailand refer to her as Thun Kramom, which implies her as the daughter of the current queen.
The family returned to Thailand after Rajakanya’s birth and she spent her early days at Amphorn Sathan Residential Hall, Dusit Palace. She was given the title Her Royal Highness Princess Ubol Ratana Rajakanya Sirivadhana Barnavadi by her father on her first birthday.
Rajakanya has one brother Vajiralongkorn, who is the current King of Thailand (Rama X) and has been ruling since 2016. While he was made crown prince when he turned 20, he ascended the throne only after the death of his father. Since, this is a patrilineal reign, Rajakanya was not granted any political power.
In 1967, when she was just 16, Rajakanya and her brother participated in the Southeast Asian Games in Bangkok in the OK Dinghy Sailing event and won gold medals for their country. She inherited her love for sports and competitions from her father.
She divided her school years between Thailand (at Chitralada School) and the United States of America. She later enrolled at Massachusetts Institute of Technology and graduated with a Bachelor of Science in Mathematics and Biochemistry in 1973.
She continued studying further and earned her Master’s in Public Health from University of California, Los Angeles in 1975.

Election Controversy
It was announced in 2019 that Rajakanya will run as a prime ministerial candidate in the upcoming general elections. She was affiliated to the Thai Raksa Chart Patry. However, her announcement was received negatively by the royal family as they had never directly involved themselves in politics.
