Flags of the World | Bhutan

Postcard
Traditionally, the sound of thunder in the many mountains and valleys of Bhutan is believed to be the voice of dragons, and the country is known as the “Land of the Thunder Dragon” in its native language.

The exact date of introduction of this flag is unknown, but it may have occurred in 1971 when Bhutan joined the United Nations. Until the 1960s Bhutan was largely closed to the outside world, so before that the country had no need for a national flag.
