Nepal’s national flag is unique in the world for its non-rectangular shape, standing out among the many rectangular flags of other nations. The flag consists of two crimson-colored triangles, one placed above the other, forming a distinctive double pennon shape. Each triangle is outlined with a navy blue border, and within the upper triangle is a white moon, while the lower triangle features a white sun. This unusual design has long intrigued people, from trivia enthusiasts to historians, as it carries layers of symbolism and mystery.
The flag’s history and symbolism are open to interpretation. Some believe the moon and sun represent the eternal nature of Nepal as a nation, while others think the triangles symbolize the Himalayan mountain range that the country is famous for. Sanjog Rupakheti, a history professor from the College of the Holy Cross and a native of Nepal, offers a different perspective. He suggests that the sun and moon may actually represent the illustrious dynasties that once ruled the region, many of which claimed descent from the sun and moon in their genealogies.
The flag’s red color is also a subject of debate. Some claim it represents Nepal's national flower, the rhododendron, while others believe it symbolizes the bravery and warrior spirit of the Nepalese people. However, Rupakheti points out that even Nepali scholars have not reached a consensus on the full meaning of the flag, leaving some aspects of its origin a mystery.
The first recorded depictions of Nepal’s flag date back to the mid-1800s, when British doctor and artist Henry Ambrose Oldfield sketched it. In 1928, travel writer Perceval Landon also documented the flag, noting that it featured the sun and moon with human faces. These early depictions, however, showed the flag with a green border rather than the current deep blue.
Nepal’s flag was not always something that ordinary people could display. Prior to the establishment of democracy in Nepal, displaying the national flag was restricted to government buildings. It wasn’t until the political changes of 1990 and again in 2008 that the flag became widely displayed throughout the country.
The flag’s distinct shape has made it a favorite subject for vexillologists (flag enthusiasts), who are drawn to its rich history and unusual design. Ted Kaye, the secretary of the North American Vexillological Association, points out that while most of Asia adopted rectangular flags due to colonial influence, Nepal’s flag remains a link to ancient traditions and designs. Kaye also calls it “the nerdiest mathematical flag,” due to the precise geometric specifications set by King Mahendra in 1962. These rules, which are now part of Nepal’s constitution, dictate the flag’s proportions, such as the number of rays on the sun, and the colors used.
Despite its beauty and historical significance, Nepal’s flag has posed challenges at international events. The flag’s non-standard shape doesn’t fit the typical 2x3 ratio required for display at the Olympics, leading to some awkward adaptations in the past. Although some Olympic organizers have attempted to fit the flag onto a white rectangular background, the International Olympic Committee has ruled that Nepal’s flag should remain in its original shape, further cementing its status as an exception to the rule.
In a world full of uniformity in national symbols, Nepal’s flag stands proudly as a symbol of tradition, mystery, and national identity.
