Sirindhorn

Who is Sirindhorn?

Princess Maha Chakri Sirindhorn is the second daughter of King Bhumibol Adulyadej.

Her full ceremonial title is “Somdet Phra Theppharatratsuda Chao Fa Maha Chakri Sirindhorn Ratthasimakhunakonpiyachat Sayamborommaratchakumari”, which was bestowned upon her on December 5, 1977. Thais commonly refer to her by reducing such title to “Phra Thep”, meaning “princess angel”.

Her title in Thai is the female equivalent of the title held by her brother, Crown Prince Maha Vajiralongkorn. The Thai constitution was altered in 1974 to allow for female succession, thus making her eligible for the throne. As the eldest female child of the royal family, her position is equivalent to a princess royal.
