Thai royal funerals are elaborate events, organised as royal ceremonies akin to state funerals. They are held for deceased members of the royal family, and consist of numerous rituals which typically span several months to over a year. Featuring a mixture of Buddhist and animist beliefs, as well as Hindu symbolism, these rituals include the initial rites that take place after death, a lengthy period of lying-in-state, during which Buddhist ceremonies take place, and a final cremation ceremony. For the highest-ranking royalty, the cremation ceremonies are grand public spectacles, featuring the pageantry of large funeral processions and ornate purpose-built funeral pyres or temporary crematoria known as merumat or men. The practices date to at least the 17th century, during the time of the Ayutthaya Kingdom. Today, the cremation ceremonies are held in the royal field of Sanam Luang in the historic centre of Bangkok.
