Early life

Prince Birabongse's parents were Prince Bhanurangsi Savangwongse and his second wife. Birabongse's paternal grandfather was King Mongkut, loosely portrayed in the Hollywood movies The King and I and Anna and the King. His mother died when Prince Birabongse was only four years old. Birabongse was sent to Europe in 1927 to complete his education in England at Eton College, where he joined one of his nephews, a grandchild of his father through his first marriage. While he was at Eton Bira's father died, leaving him an orphan. He was placed under the care of his cousin, Prince Chula Chakrabongse, who ultimately became Prince Bira's legal guardian. On leaving Eton at age 18, in early 1933, Prince Bira moved in with Prince Chula in London, while he decided on his future.
