The Kingdom of Siam or The Rattanakosin Kingdom (Thai: อาณาจักรรัตนโกสินทร์) was founded in 1782 with the establishment of Rattanakosin as the capital city. The failure to implement substantial political reforms culminated in the 1932 revolution and the abandonment of absolute monarchy in favor of a constitutional monarchy.

Sansoen Phra Barami was the de facto national anthem of Siam from 1888 until 1932. The music of Siamese national anthem, was written by the Russian composer Pyotr Schurovsky. In 1913, King Vajiravudh decided to relinquish all lyrics of "Sansoen Phra Barami" and revised it to current version. It still use as the royal anthem of Thailand today.
