Oh homeland, my homeland Listen to the pain of my words I am the nightingale of this garden All my body and soul All with one name and symbol With different colors and languages
If you compare the old anthem (above) to the the new, post-Islamic Revolution anthem (below) you can notice a big change. The new anthem is less about the homeland and people and more about God.
Portion of the lyrics from Iran's new anthem (Islamic Republic):
The month of Bahman is the brilliance of our Faith. Your message, O Imam, of Independence and Freedom is imprinted on our souls. O Martyrs! Your clamours echo in the ears of time: Enduring, continuing, eternal, The Islamic Republic of Iran.
