With the death of King Bhumibol of Thailand, who was the world’s longest reigning monarch at the time of his death, the country enters into a period of mourning under a regent until the accession of Crown Prince Maha Vajiralongkorn.

While the former Kingdom of Siam made use of an emblem a bit more similar to the western idea of a coat of arms the current royal emblem or “arms”, which appears on the yellow royal standard, is the Buddhist Garuda.
Appearing in the Hindu epic, the Ramayana, Garuda is the mystical firebird who serves as the mount of the god Vishnu. Garuda appears as the coat of arms of the Republic of Indonesia as well as the royal emblem of the Kingdom of Thailand.
