National flag

Johnson's new chart of national emblems, published c. 1868. The large flags shown in the corners are the 37-star flag of the United States (flown 1867–1890), upper left; the Royal Standard of the United Kingdom, upper, right; the Russian Imperial Standard, lower left; and the French tricolore with inset Imperial Eagle, lower right. Various other flags flown by ships are shown. The Flag of Cuba is labelled "Cuban (so called)". The Chinese dragon on the Flag of China was drawn mistakenly as a western dragon.

A national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but can also be flown by its citizens. A national flag is typically designed with specific meanings for its colours and symbols, which may also be used separately from the flag as a symbol of the nation. The design of a national flag is sometimes altered after the occurrence of important historical events.
