They also have a very clever flag:
The elephant comes from the flag used by Thailand from the 19th century until 1917; there were variants with a simple and an adorned with royal regalia elephant, and it was actually a white elephant on a red field. It seems obvious the option for the elephant as a royal symbol. On the top of the flag, there's a representation of the sheet knot, initially used by FIAV (Federation of International Associations of Vexillology) and then by many other associations of vexillology; the knot represents the nautical origins of the flags. The knot is adorned with the colors of the current Thailand flag.
The current Thailand flag was adopted in 1917. According to a story, the king Rama VI, when seeing the elephant flag flying upside-down, decided to adopt a totally symmetrical design. Initially, the middle stripe was red, but soon it was changed to blue. The symbology of the colors is the following: red for land and people, white for all religions, and dark blue for monarchy (the astrologers considered the color auspicious to Rama VI). Moreover, the flag was adopted during World War I, and had the same colors of the flags of some Allies: the USA, the United Kingdom and France. Having a good and exclusive design, the flag remains without problems since then.
