The flag of Iran features three horizontal stripes in green, white, and red from top to bottom. Green symbolizes growth and Islam, white represents peace, and red stands for courage and martyrdom. In the center of the white stripe is a red emblem that combines various Islamic symbols to resemble the word "Allah" and symbolizes the principles of the Iranian Revolution. The flag's inner edges of the green and red bands are inscribed with the phrase "Allahu Akbar" ("God is Great") repeated 22 times, marking the date of the revolution in the Islamic calendar. This current design was adopted on July 29, 1980, following the 1979 revolution that established the Islamic Republic of Iran.
