Jessadabodindra

Phra Bat Somdet Phra Poramadhiworasettha Maha Jessadabodindra Phra Nangklao Chao Yu Hua (Thai: พระบาทสมเด็จพระปรมาธิวรเสรฐมหาเจษฎาบดินทร์ พระนั่งเกล้าเจ้าอยู่หัว; RTGS: —Chetsadabodin Phra Nang Klao Chao Yu Hua), or Rama III ( 31 March 1787 – 2 April 1851), was the third monarch of Siam under the House of Chakri, ruling from 21 July 1824 to 2 April 1851. He succeeded his father, Buddha Loetla Nabhalai, as the King of Siam. His succession was unusual according to the traditions because Jessadabodindra was a son of a concubine rather than a queen. He surpassed Prince Mongkut, who was a legitimate son of Buddha Loetla Nabhalai born to Queen Srisuriyendra.
