(I) Every country has a national flag with a unique design that identifies it to other countries. (II) There are no international rules for flag design; each country can choose any pattern, though they are usually based on the country’s history or culture. (III) National flags first became widespread in the 19th century, but Denmark has the oldest national flag still in use, dating back as far as the 13th century. (IV) Most flags are rectangular in shape, but the proportions of the rectangle are not always the same. (V) However, this is not always the case – Nepal, for example, has a distinctive, non-rectangular flag, which looks like two triangles on top of each other.
