Pahlavi dynasty in the context of "List of monarchs of Iran"

King of Kings was an imperial title employed primarily by monarchs based in the Middle East and the Indian subcontinent. Commonly associated with Iran (historically known as Persia in the West), especially the Achaemenid and Sasanian Empires, the title was originally introduced during the Middle Assyrian Empire by King Tukulti-Ninurta I (reigned 1233–1197 BC) and was subsequently used in a number of different kingdoms and empires, including the aforementioned Persia, various Hellenic kingdoms, India, Armenia, Georgia, and Ethiopia.

The title is commonly seen as equivalent to that of Emperor, both titles outranking that of king in prestige, stemming from the late antique Roman and Eastern Roman emperors who saw the Shahanshahs of the Sasanian Empire as their equals. The last reigning monarchs to use the title of Shahanshah, those of the Pahlavi dynasty in Iran (1925–1979), also equated the title with "Emperor". The rulers of the Ethiopian Empire used the title of Nəgusä Nägäst (literally "King of Kings"), which was officially translated as "Emperor". Sultan of Sultans is the sultanic equivalent of King of Kings and similarly, Khagan can mean "Khan of Khans". Later, lesser versions Amir al-umara ("Emir of Emirs") and Beylerbey ("Bey of Beys") appeared.

The Iranian Revolution or the Islamic Revolution was a series of events that culminated in the overthrow of the Pahlavi dynasty in 1979. The revolution led to the replacement of the Imperial State of Iran by the Islamic Republic of Iran, as the monarchical government of Shah Mohammad Reza Pahlavi was superseded by Ruhollah Khomeini, an Islamist cleric who had headed one of the rebel factions. The ousting of Mohammad Reza Pahlavi, the last Shah of Iran, formally marked the end of Iran's historical monarchy.

In 1953, the CIA- and MI6-backed 1953 Iranian coup d'état overthrew Iran’s democratically elected Prime Minister, Mohammad Mossadegh, who had nationalized the Anglo-Persian Oil Company. The coup reinstated Mohammad Reza Pahlavi as an absolute monarch and significantly increased United States influence over Iran.

Reza Shah Pahlavi (previously Reza Khan; 15 March 1878 – 26 July 1944) (Persian: رضاشاه پهلوی [ɾeˈzɒː ˈʃɒːhe pʰæɦlæˈviː]) was an Iranian military officer and monarch who was the founder of the Pahlavi dynasty and Shah of Iran from 1925 to 1941. Originally an army officer, he became a politician, serving as minister of war and prime minister of Iran, and was elected shah following the deposition of Ahmad Shah, the last monarch of the Qajar dynasty.

Joining the Persian Cossack Brigade at age 14, he rose through the ranks, becoming a brigadier-general by 1921. In February 1921, as leader of the entire Cossack Brigade based in Qazvin province, he marched towards Tehran and seized the capital. He forced the dissolution of the government and installed Zia ol Din Tabatabaee as the new prime minister. Reza Khan's first role in the new government was commander-in-chief of the army and the minister of war. Two years after the coup, Seyyed Zia appointed Reza Pahlavi as Iran's prime minister, backed by the compliant national assembly of Iran. In 1925, the constituent assembly deposed Ahmad Shah Qajar, the last Qajar shah, and amended Iran's 1906 constitution to allow the election of Reza Pahlavi as the Shah of Iran. He founded the Pahlavi dynasty that lasted until it was overthrown in 1979 by the Iranian Revolution.

Mohammad Reza Pahlavi (Persian: محمدرضا پهلوی [mohæmˈmæd reˈzɒː pæhlæˈviː]) (26 October 1919 – 27 July 1980) was the Shah of Iran from 1941 to 1979. He succeeded his father Reza Shah and ruled the Imperial State of Iran until he was overthrown by the 1979 Islamic Revolution led by Ruhollah Khomeini, which abolished the Iranian monarchy to establish the Islamic Republic of Iran. In 1967, he took the title Shahanshah (lit. 'King of Kings'), and also held several others, including Aryamehr (lit. 'Light of the Aryans') and Bozorg Arteshtaran (lit. 'Grand Army Commander'). He was the second and last ruling monarch of the Pahlavi dynasty.

During World War II, the Anglo-Soviet invasion of Iran forced the abdication of Reza Shah and succession of Mohammad Reza Shah. During his reign, the British-owned oil industry was nationalized by the prime minister Mohammad Mosaddegh, who had support from Iran's national parliament to do so; however, Mosaddegh was overthrown in the 1953 Iranian coup d'état, which was carried out by the Iranian military under the aegis of the United Kingdom and the United States. Subsequently, the Iranian government centralized power under the Shah and brought foreign oil companies back into the country's industry through the Consortium Agreement of 1954.

The Arab conquest of Iran, which culminated in the fall of the Sasanian Empire to the nascent Rashidun Caliphate, brought about a monumental change in Iranian society by purging Zoroastrianism, which had been Iran’s official and majority religion since the time of the Achaemenid Empire. Since the Rashidun invasion, Islam (in any form) has consistently held the status of Iran's official religion except for a short period in the 13th century, when the Mongol invasions and conquests destroyed the Abbasid Caliphate and smaller Islamic realms before resulting in the establishment of the Ilkhanate. The process by which Iranian society became integrated into the Muslim world took place over many centuries, with nobility and city-dwellers being among the first to convert, in spite of notable periods of resistance, while the peasantry and the dehqans (land-owning magnates) took longer to do so. Around the 10th century, most Persians had become Muslims.

Between the 7th century and the 15th century, Sunni Islam was the dominant sect in Iran, and Iranian academics of this period contributed greatly to the Islamic Golden Age. In the 16th century, the newly enthroned Safavid dynasty initiated a massive campaign to install Shia Islam as Iran's official sect, aggressively proselytizing the faith and forcibly converting the Iranian populace. The Safavids' actions triggered tensions with the neighbouring Sunni-majority Ottoman Empire, in part due to the flight of non-Shia refugees from Iran. It is estimated that by the mid-17th century, Iran had become a Shia-majority nation. Over the following centuries, with the state-fostered rise of an Iran-based Shia clergy, a synthesis was formed between Iranian culture and Shia Islam that marked each indelibly with the tincture of the other. Later, under the Pahlavi dynasty, Islamic influence on Iranian society was rolled back in order to assert a new Iranian national identity—one that focused on pre-Islamic Iran by shedding more light on Zoroastrian tradition and other aspects of ancient Iranian society, particularly during the Achaemenid era. However, in 1979, the Islamic Revolution brought about yet another monumental change by ending the historic Iranian monarchy and replacing it with an Islamic republic.

Iranian nationalism is nationalism among the people of Iran and individuals whose national identity is Iranian. Iranian nationalism consists of political and social movements and sentiments centered around support for Iranian culture, Iranian languages and history, and a sense of pride in Iran and Iranian people. While national consciousness in Iran can be traced back centuries, nationalism has been a predominant determinant of Iranian attitudes mainly since the 20th century.

Modern Iranian nationalism rose during the 1905 Persian Constitutional Revolution, when an atmosphere of unity and Iranian patriotic sentiments began. During the Pahlavi dynasty between 1925 and 1979, Iranian nationalism experienced a resurgence due to the Pahlavi government's bolstering of patriotic sentiment.
