Iran has designated April 30th as the National Persian Gulf Day. Persian Gulf, a historical waterway, is part of the natural heritage of Iran. The day marks the anniversary of the expulsion of Portuguese military forces from the Strait of Hormuz in 1622, during the reign of Safavid king Shah Abbas I (1587-1629).

In January 1963, the Shah of Iran held a national referendum to obtain approval for his total program which was known as the White Revolution  or the Revolution of the Shah and the People.

To many Iranian’s March 20 is the reminder of an event that changed the course of history for their country; it was in such a day back in 1951 when Iran’s then parliament voted unanimously in favor of the nationalization of oil in Iran. The idea was introduced in a bill to the parliament by Iran’s democratically elected Prime Minister Mohammad Mosaddeq with the support of his nationalist party and religious groups led by Ayatollah Kashani. 

The forceful removing of hijab (Islamic code of dress for women) in Iran signified a special part of the contemporary Iranian history under the rule of Reza Shah Pahlavi during which Iranian women and girls were banned from wearing hijab including various kinds of chador, veil, and headscarf.

Mirza Taqi Farahani was born in 1807 in Farahan, Iran, entitled Ataback-e Azam (The Chief Minister), Amir Nezaam (The Prince of the State), and Amir Kabir (The Great Prince), is one of the greatest politicians in the recent two centuries of Iran. He initiated reforms that marked the effective beginning of the modernisation of Iran.

A cursory glance at the contemporary history of Iran will reveal that although the black gold (crude oil) is counted among the God-given bounties of Iranians for many years, the colonialistic British government had been holding a firm grip on it for many years. That grip had been so firm that according to available historical evidence, the benefits of Iran's crude oil resources were divided at a ratio of 1:6 in favor of the British side.

At dawn this date in 1954, the last Foreign Minister of democratic Iran was shot in Tehran. It was a year since the dramatic events of 1953, when a CIA-backed coup d’etat overthrew Iranian Prime Minister Mohammed Mossadegh for contemplating oil nationalization.

Although Iran proclaimed neutrality in the war, several battles were fought in western Iran between Russian and Ottoman forces. These battles destroyed many villages, killed several hundred Iranian civilians, and caused near-famine conditions that probably caused the death of several thousand more. The inability of the Iranian government to protect the country provoked rebellions and autonomy movements in northern Iran between 1915 and 1921.

This treaty was a dark page in Iran's history, containing a document involving Great Britain and Persia (Iran) and centered around drilling rights of the Anglo-Persian Oil Company. It was never ratified by the Majlis. The "agreement" was issued by British Foreign Secretary Earl Curzon to the Persian government in August of 1919. It stated a guarantee of British access to Iranian oil fields (including five northern provinces formerly under the Russian sphere of influence). Eventually, the Anglo-Persian agreement was formally denounced by the Iranian Parliament (Majlis) on June 22, 1921.

Mohammad Shah, son of Abbas Mirza, FathAli Shah's prince crown was the third Qajar Shah. When the news of FathAli Shah's death reached Mohammad Mirza in Tabriz, he coronated in the same city, and proceeded with his forces to Tehran and encountered his uncle, Sultan Ali Mirza Zil-los-Sultan's forces in the vicinity of Tehran.
