Sansoen Phra Barami

In 1851, two former British military officers named Captain Impey and Lieutenant Thomas George Knox served with the Siamese Army.

Phraya Srisunthonwohan (Noi Āchāryānkura) wrote Thai lyrics for this anthem later and named it as "Chom Rat Chong Charoen", which means "long live the great king".

A group of Siamese traditional musicians had selected a Thai song named "Bulan Loi Luean" which was the royal composition of King Rama II for use as the new anthem.

King Chulalongkorn later ordered Christopher Hewetson,[1] a Dutch bandmaster who served in the Royal Siamese Army, to arrange the song in western style for performing by the military band.

According to a research of Sugree Charoensook, Pyotr Shchurovsky was the composer of the music of "Sansoen Phra Barami",[3] to serve as Siam's national anthem.

After the end of World War II, these lyrics were quietly abandoned due its unpopularity, and reverted to the version that revised by King Vajiravudh in 1913.

The anthem is also played at the sign-on and closedown of television and radio programming; for example, in 2008, 7HD aired a video with pictures of King Bhumibol Adulyadej from his birth to his 80th birthday in 2007.
