The flag of Thailand (Thai: ธงไตรรงค์; RTGS: thong trai rong, meaning 'tricolour flag') consists of five horizontal stripes of red, white, blue, white and red, with the central blue stripe being twice as wide as each of the other four. The design was adopted on 28 September 1917, according to the royal decree issued by Rama VI. The colours are said to stand for nation-religion-king, an unofficial motto of Thailand, red for the land and people, white for religions and blue for the monarchy, the last having been the auspicious colour of Rama VI.
