Ey Iran" is an Iranian nationalist song that serves as the country's unofficial national anthem.
Composer: Ruhollah Khaleghi
Lyrics: Hossein Gol-e-Golab
The song's history dates back to World War II in Iran.
After the Revolution of 1979, several people were imprisoned for collaborating in the preparation of this anthem, and reading it was considered a crime, but after a while, it was used to provoke soldiers in the Iran–Iraq War, and it was released.
