The national anthem of Thailand was adopted on 10 December 1939. The anthem was composed a few days after the 1932 coup, and was first broadcast in July 1932. The original lyrics were by Khun Wichitmatra. In 1939, when the name of the country was changed from Siam to Thailand, a competition was launched to create new lyrics, with those by Luang Saranupraphan winning. Prime minister Phibunsongkhram ordered the anthem to be played every day at 8.00 and 18.00, with everyone having to stand up to show respect for the nation. That law is still in force today.— Excerpted from Thai National Anthem on Wikipedia, the free encyclopedia.
