The French Imperial Eagle (French: Aigle de drapeau, lit. 'flag eagle') was a figure carried into battle as a standard by the Grande Armée of Napoleon I during the Napoleonic Wars.
Although they were presented with regimental colours, Napoleon's regiments tended to carry at their head the Imperial Eagle.
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 colors 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.
