History of Iran’s flag
Early symbolism and traditional colors
The colors green, white, and red have long been associated with Iran and its national identity.
These colors later appeared together in Iranian flags during the 19th century and eventually formed the basis of the modern national flag.
Adoption of the modern tricolor
The modern Iranian tricolor emerged during the Constitutional Revolution in the early 20th century, when Iran introduced constitutional reforms and modern state symbols.
In 1907, the Supplementary Fundamental Laws described the national flag as a tricolor of green, white, and red with the lion and sun emblem in the center.
In 1910, a decree standardized the design of the emblem, specifying details such as the shape of the lion’s tail and the position and size of the lion, sword, and sun.
Changes after the Islamic Revolution
Following the 1979 Islamic Revolution, the monarchy was abolished and the lion and sun emblem was removed.
On 29 July 1980, the current design was adopted, featuring a stylized Islamic emblem and decorative inscriptions of “Allahu Akbar.”
