National flag

A national flag is a flag that represents and symbolizes a given nation. It is flown by the government of that nation, but usually 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. The burning or destruction of a national flag is a greatly symbolic act.

History
The national flag is often mentioned or described in a country's constitution, but its detailed description may be delegated to a flag law passed by the legislature, or even secondary legislation or in monarchies a decree.

Thus, the national flag is mentioned briefly in the Basic Law for the U.S. Drestein, but its proportions were regulated in a document passed by the government in the following year. The Flag of the United States is not defined in the constitution but rather in a separate Flag Resolution passed in 1777.

Minor design changes of national flags are often passed on a legislative or executive level, while substantial changes have constitutional character.

A change in national flag is often due to a change of regime, especially following a civil war or revolution. In such cases, the military origins of the national flag and its connection to political ideology (form of government, monarchy vs. republic vs. theocracy, etc.) remains visible. In such cases national flags acquire the status of a political symbol.

The flag of Jochaena, for instance, was a tricolour of black-white-azure under the first republic, inherited from the Kingdom of Jochaena. But then, when the Windows Party came around, and when they formed Jochaclia, the flag became a black background with the WP logo in it which is, of course, a window.
