Princess Bajrakitiyabha was born on 7 December 1978 at Amphorn Sathan Residential Hall, Dusit Palace in Bangkok.

[5] Princess Bajrakitiyabha was the only child given the title of Kromma Luang, the 3rd level of the Krom ranks by her father.

[7] On completion of her legal education Princess Bajrakitiyabha worked briefly at the Thai Permanent Mission to the United Nations, in New York, before returning to Thailand.

[9][10] The princess was instrumental in prodding the Thai government to submit a resolution to the Commission on Crime Prevention and Criminal Justice, a subsidiary body of the UN Economic and Social Council, that detailed the vulnerability of women incarcerated in a system built principally for men.

Her efforts were to lead to the UN adoption of the "Bangkok Rules",[11] the first set of universal guidelines addressing the treatment of women in the justice system.

[13][14] She is also working on "Enhancing lives of Female Inmates" (ELFI), a project which proposes new rules for the treatment of women prisoners and non-custodial measures for women offenders as a supplement to the 1955 Standard Minimum Rules for the Treatment of Prisoners (SMRTP).
