Flag of Thailand

The flag of Thailand is a beautiful symbol with five horizontal stripes. The colors are red, white, blue, white, and red again, with the blue stripe in the middle being twice as wide as the others. This special design was chosen on 28 September 1917 by a king named Rama VI.

The colors of the flag have important meanings. Red stands for the land and the people of Thailand, white represents religions, and blue is for the monarchy, which was a favorite color of Rama VI. The flag was changed around the time Thailand declared war on Germany, and it now shares the same colors as flags from countries like the UK, France, Russia, and the United States.

Since 2016, the day the flag was adopted is celebrated as an important national day in Thailand, showing how much the flag means to the country. It reminds everyone of the nation-religion-king idea that is important in Thailand.

Design

The Flag Act of BE 2522 (1979) says the Thai flag is a rectangle that is 6 parts wide and 9 parts long. It has five horizontal stripes: red, white, blue, white, and red. The blue stripe in the middle is twice as wide as the other stripes.

The Thai flag looks a lot like the Flag of Costa Rica because both have five horizontal stripes of red, white, and blue, with the center stripe being twice as thick. The only difference is the order of the colors.

Colour standards

In 2017, Thailand set the colors for the flag. These colors help make sure all flags look the same.

History

The first flag used for Siam was probably a plain red one. Later, ships used different symbols on a red background.

In 1855, Mongkut, also known as Rama IV, made an official flag with a white elephant on a red background.

In 1916, the flag changed to show a white elephant wearing special royal clothes. That same year, a new design was made. At first, the flag had five horizontal stripes of red and white. Later in 1917, the middle stripe was changed to dark blue.

Maritime flags

The naval ensign of the Royal Thai Navy is the national flag with a red circle in the middle. Inside the circle is a white elephant facing the flag's pole. The kingdom's naval jack is the national flag with the Royal Thai Navy emblem in the middle. The RTN's regimental colours look the same as this flag. Both ensigns were adopted in 1917.
