Ey Iran, ey marze porgohar (O Iran, o bejeweled land) is an Iranian patriotic song. Many consider it to be the de facto national anthem of Iran.
Wikipedia has this to tell us about Ey Irân:
“Ey Irân” anthem was composed in 1944 in Tehran. The lyrics were written by Hossein Gol-e-Golab and the music was composed by Ruhollah Khaleqi, and it was first performed by the classical Persian music singer Gholam-Hossein Banân.
Golegolâb was inspired to write the song by patriotism. He has been quoted to have said: “In 1944, the footsteps of the invading armies in the streets were enough to rattle any patriot and inspired me to write this anthem. Professor Ruhollâh Khâleqi wrote the music and despite all the political opposition, it found its way into the heart and soul of the people.”
… it occupies a place in Iranian popular culture similar to that of Men of Harlech in Wales.
That’s interesting, Pejman! We perfectly understand that, as an Iranian, this is a song close to your heart, but what has it got to do with the city of Lille in France?
