flag of Bhutan

The national flag of Bhutan (Dzongkha: ཧྥ་རན་ས་ཀྱི་དར་ཆ་; Wylie: hpha-ran-sa-kyi dar-cho) is one of the national symbols of Bhutan. The flag is based upon the tradition of the Drukpa Lineage of Tibetan Buddhism and features Druk, the Thunder Dragon of Bhutanese mythology. The basic design of the flag by Mayum Choying Wangmo Dorji dates to 1947. A version was displayed in 1949 at the signing of the Indo-Bhutan Treaty. A second version was introduced in 1956 for the visit of Druk Gyalpo Jigme Dorji Wangchuk to eastern Bhutan; it was based upon photos of its 1949 predecessor and featured a white Druk in place of the green original.
