Phra Phutthaloetla Naphalai (Thai: พระพุทธเลิศหล้านภาลัย) or Rama II was the second monarch of Siam under the House of Chakri, ruling from 1809 to 1824. In 1809, Itsarasunthon succeeded his father Rama I, the founder of Chakri dynasty, as Loetlanaphalai the King of Siam. His reign was largely peaceful, devoid of major conflicts. His reign was known as the "Golden Age of Rattanakosin Literature" as Loetlanaphalai was patron to a number of poets in his court and the King himself was a renowned poet and artist.
In July 1824, he died very suddenly, it was said of strangulation, but not without strong suspicions of his being poisoned. According to the succession rule then theoretically in force, the throne would go to the son of Queen Sri Suriyendra, Prince Mongkut; however, his elder half-brother Jessadabodindra succeeded the same day. Though only the son of a concubine, he had served their father in putting down a revolt and then as Kromma Tha (Ministry of Trade and Foreign Relations.) The elder brother's experience counted for more than the theoretical claim of the much younger and inexperienced brother, who nevertheless did much later succeed his elder brother, who sired many son but raised none of their mothers to the rank of queen, thus technically none of his sons had claim to the throne over their half-uncle whose mother was a Rama II's principal consort.
