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.

    1855

    King Mongkut makes the white elephant flag official. A plain red cloth was not enough to tell Siam apart from other countries.

  5. Flag of five red and white stripes

    1916-1917

    Vajiravudh replaces the elephant with five red and white stripes.

  6. Current flag of Thailand

    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

  1. 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.

  2. 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.

  3. It has its own day

    Since 2017, 28 September is National Flag Day, in memory of the day the tricolour was adopted.
