Sanam Luang has been used since the time of King Rama I. It was the place for royal ceremonies and functions. Including the cremation of the Prince of the Palace to the Front, who was Rama I's brother. King Rama II followed this example of performing royal ceremonies there, including the cremation of the Prince of the Palace to the Front of his reign, who was also his beloved brother. The Royal Chronicles mention the close link between the two brothers as follows :
"At the beginning of the season of the tradewind, the king flew a Chula kite (star-shaped kite) in front of the Temple of the Emerald Buddha and the Prince of the Palace to the Front flew a Pakpao kite (plain kite) at Sanam Luang".
During the reign of King Rama III, when Thailand was engaged in a conflict with Vietnam over the Cambodian border, the King wished to demonstrate to other nations that Thailand was such a fertile, flourishing country that even the area in front of the Grand Palace was cultivated. Sanam Luang was then a normal plot of land, used for growing rice. When there was a Royal Funeral, it would be smoothed over to prepare for the event.
