National flag of Nepal - World's only Non-Quadrilateral Flag

The national flag of Nepal is the only flag in the world that is not rectangular and serves as both the state flag and the civil flag of an independent country.

The flag is a double pennon, which is a reduced version of two single pennons. Its deep red color stands for bravery, which is also the color of Nepal's national flower, the rhododendron.The blue border of the flag stands for peace. Both the sun and the crescent moon on the flag had faces until 1962, when they were taken off to make the flag look more modern.

The current flag was chosen on December 16, 1962, the same day that a new parliamentary government was put in place. King Mahendra asked a construction engineer named Shankar Nath Rimal to make the flag more uniform.

The flag of Nepal is a combination of the two separate pennons used by rival branches of the ruling family during the 19th and 20th centuries. The flag is based on the original, traditional design, which was used throughout the 19th and 20th centuries.

The ancient Gorkha kingdom's flag began as a single triangular war banner of the Shah kings, with red color and various deities and other symbols as symbols in the flag. After Prithvi Narayan Shah unified all of Nepal's small principalities, the double-pennon flag became the standard flag.
