Iran is an Islamic country owes its Islamic dimensions to the great revolution, known as the Iranian Islamic Revolution of 1977 (1357 SH), which done by huge crowd participation of the public, Islamic characters, clerics, students, merchants, opposing political parties, intellectuals and etc., who expressed their dissatisfaction with the situation of the Imperial regime in many different ways as clashes, general strikes, street demonstrations and protests, from a long time ago.
The main root of Islamic Republic of Iran can be found in the 1953 coup (known in Iran as 28 Mordad coup) and its concurrent events; the cause of developing the Islamic movement can be counted as follows: absolute attachment to the West, specially to US, kings not authorized to make important decisions, corrupt and irreligious kings who tried to deceive the young, ignorance of the people’s vote, confrontation with liberalism, pervasiveness of oppression and injustice supported by the government, scientific, industrial undeveloped and the lack of amenities.
Following this anti-royal revolution on February 11th (22nd of Bahman), the struggle of the Muslim people finally worked to the fore and the kingdom of Iran was overthrown and the setting for the coming of the Islamic Republic under the leadership of the Shiite cleric, Seyyed Rouhollah Khomeini, was provided.
The 10 days between February 1st (Bahman 12th) and February 11th (Bahman 22nd) of 1977 (1357) are called Fajr Decade; which Imam Khomeini entered to Iran after the fifteenth years of exile, and the greatest welcome in history took place from him in Tehran, and eventually the Pahlavi regime was extinct after more than 50 years of oppression and tyranny on February 23rd. After the triumph of the revolution, a referendum was held on creating the Islamic Republic on 28 July 1979; it was approved by 98.2% of eligible citizens.
On the occasion of this great victory, the Iranian nation decorates the cities, streets and different areas with different decorative objects, flowers, the picture of Imam Khomeini and Sayyed Ali Khamenei, the supreme leader of Iran, and the flag of the Islamic Republic of Iran during the Fajr decade every year. Iranians also celebrate this decade with performing revolutionary songs, holding various festivals as Fajr (the most extensive film, theatre and music festival in Iran), holding different ceremonies in governmental organizations and centers across the country.
