The event is marked every year on 22nd of Bahman on Iranian calendar to celebrate the historic victory.
On this day, the wise leadership of the great Imam Khomeini put an end to the monarchy of the US-backed Pahlavi regime in the country
Iranian people rallied onto the streets today to reaffirm their allegiance to the ideals of the late founder of the Islamic Republic Ayatollah Ruhollah Khomeini.
Excusive and special ceremonies are also being held at home and abroad to remember the 22nd of Bahman and the day in 1979 when Ayatollah Khomeini returned to the Iranian capital after 14 years living in exile.
The day of Imam Khomeini's return to Iran marks the beginning of celebrations, dubbed Ten Days of Dawn, which culminate in the anniversary of the victory of the Islamic Revolution in around mid February.
The Iranian nation toppled the US-backed Pahlavi regime 35 years ago, ending 2,500 years of monarchic rule in the country.
The Islamic Revolution, under the guidance of Imam Khomeini, established a new political system based on Islamic values and democracy.
Imam Khomeini became voice of the voiceless and strengthened the Iranian nation and oppressed people around the globe. He is recognized as the leader and well-wisher of the whole Islamic Ummah and is widely respected by all followers of the different divine faiths.
