Flag of Iran

The national flag consists of three equal horizontal stripes of green, white, and red arranged from top to bottom. A red emblem featuring four crescents and a central sword is situated in the center of the white band. Stylized white Kufic script lines the lower edge of the green stripe and the upper edge of the red stripe.

Green symbolizes the Islamic religion and growth, white represents peace, and red commemorates the blood of martyrs and national courage. The central emblem is designed to resemble a tulip while simultaneously forming the word "Allah" and the Islamic declaration of faith. Repetition of the phrase "Allahu Akbar" in the Kufic script emphasizes the country's religious identity.

Following the 1979 Revolution, this version of the flag was officially adopted on July 29, 1980, to replace the monarchical Lion and Sun emblem. Hamid Nadimi created the central design, which was formally approved by Ayatollah Khomeini for use by the new Islamic Republic. Although the green-white-red tricolor dates back to the early 20th century, the specific graphical elements were modified to reflect the change in government. The inclusion of the Kufic script twenty-two times specifically commemorates the revolution occurring on the 22nd day of Bahman.
