The full story
How it was born, how it has changed and what it means.
The flag of Thailand has five horizontal stripes: red, white, blue, white and red. The blue stripe in the centre is twice as wide as the others. In Thai it is called Thong Trairong, which means ‘the tricolour flag’.
How it came about
Thailand was called Siam until 1939. Its first flag was probably a plain red cloth, used in the 17th century. Over time the kings added their symbols to it, above all the white elephant, a sacred animal linked to royalty.
In 1916 King Vajiravudh decided to replace the elephant flag with a simpler design of red and white stripes that would look the same however it was hung. A year later, on 28 September 1917, the middle stripe became blue. That same summer Siam had entered the First World War alongside France, the United Kingdom and the United States, whose flags are also red, white and blue.
How it has changed
In three centuries the flag went from a red cloth to an elephant and, at the end, to stripes.
Vajiravudh replaces the elephant with five red and white stripes.
1917
The middle stripe becomes blue and wider. It is the current flag.
What it means
The law does not explain it, but the most widespread reading ties the three colours to the motto ‘nation, religion, king’:
Red
the nation and its people.
White
the religion, above all Buddhism.
Blue
the monarchy. It is said to have been the colour of King Vajiravudh, although sources do not agree on the reason.
Fun facts
An elephant hung upside down
According to a much-repeated story, in 1916 the king saw an elephant flag hung upside down during some floods and decided to create one that could not be put on wrong. It is an unconfirmed popular anecdote.
The country stops twice a day
Every day, at 8 am and 6 pm, the anthem plays on the radio, on television and in many public places while the flag is raised or lowered. The custom is to stop and stay still until it ends.
It has its own day
Since 2017, 28 September is National Flag Day, in memory of the day the tricolour was adopted.
