The national flag of Nepal (Nepali: नेपालको झण्डा) is the world’s only non-quadrilateral national flag. The flag is a simplified combination of two single pennons, the vexillological word for a pennant. Its crimson red is the colour of the rhododendron, the country’s national flower. Red is also the sign of victory in war.[citation needed] The blue border is the colour of peace. Until 1962, the flag’s emblems, the sun and the crescent moon, had human faces. They were removed to modernize the flag.
