The flag of Nepal is in the shape of two pennants, one sewn on top of the other. They symbolize the Rana dynasty’s two branches, which ruled the country from 1846 to 1951. In the 1800s, the two red pennants were joined to represent the nation of Nepal, and in 1962 the conjoined form was officially adopted by Nepal’s constitutional government. To the Nepalese today, the flag symbolizes the country’s two religions – Hinduism and Buddhism – living side by side.
Pennants like Nepal’s flag used to be common for regional flags in Asia. But the rectangular flag, common in European countries, eventually took hold around the world, replacing regional symbols of allegiance.
