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. 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.
