Royal flags of Thailand

The Royal Flags of Thailand (Thai: ธงประจำพระองค์) are royal flags that can be flown in Thailand. They are also flown with the National flag. They are used to honor the King and Royal Family. Unlike the Royal Standards displayed only in special ceremonies and in particular locations, the Royal Flags are seen in Thailand. They are not usually seen outside of the country.

Flag of the King

The King's flag is in yellow, the color of Monday, the day of his birth. It always has a symbol in the middle. There are a variety of symbols,^[1] but recently most king's flags have different symbols, such as the symbol marking King Bhumibol's 80th birthday or the one commemorating the 60th anniversary of King Bhumibol's accession to the throne.^[2]

Both emblems in the center of the flag are quite complex, involving Buddhist iconography and ancient royal symbols of authority as well, such as the multi-tiered white umbrella.^[3] The king's symbols are always topped by the royal crown. Sometimes light rays are emanating from the top of the crown, these are also an element of royal symbology. In simplified versions of the flag the central symbol may come simply outlined in red.

Yellow is the color identified with the king in Thailand (as well as the previous king, both were born on a Monday). Many Thais like to wear yellow shirts as an informal homage to their king, especially on Mondays, the day of his birth.
