The flag of Peru was adopted by the government of Peru in 1825. It is a vertical triband with red outer bands and a single white middle band. Depending on its use, it may be defaced with different emblems, and has different names.
June 7, the anniversary of the Battle of Arica, is celebrated as Flag Day.
The national or civil flag (Spanish: bandera nacional) is used by citizens. It has no additions to the common form. It was changed several times; before 1950 it looked like the current national flag and was used as both the civil and state flag, when General Manuel A. Odría removed the coat of arms from the national flag and created the state and war flags.
