Every year, Iranians mark the anniversary of their Islamic Revolution from February 1 to 11, known as the Ten-Day Dawn ceremonies. During the celebrations, Iranians take part in different events and activities to mark the occasion.
Led by Imam Khomeini, the Islamic Revolution was driven by anti-imperialist sentiments since former Iranian monarch Mohammad Reza Pahlavi was heavily dependent on Western powers, not least the United States.
By toppling the Pahlavi regime 46 years ago, the Iranian nation ended 2,500 years of monarchic rule and established a new political system – a republic based on Islamic values and democracy.
