The national flag of Bhutan consists of a white dragon over a yellow and orange background. The flag is divided diagonally from the lower hoist side corner, making two triangles. The upper triangle is yellow and the lower triangle is orange. The dragon is centered along the dividing line, facing away from the hoist side.
The upper half of the flag, which is yellow in color represents the secular authority of His Majesty the King.
The lower orange half of the flag represents Mahayana Buddhism, the state religion.
The dragon running diagonally across the middle of the flag is no ordinary dragon. This is the Thunder Dragon, and the country takes its name from this dragon. The indigenous name of Bhutan is Druk Yul meaning the land of the thunder dragon. The color of the dragon is white, representing the loyalty of the various ethnic and linguistic groups in the country. The country’s wealth and perfection are the jewels clasped in the dragon’s claws, protected by the strength of the deities expressed by the snaring mouth of the dragon.
