Pahlavi Iran

Empire · 1925–1979

The Pahlavi state rose from the wreckage of Qajar Iran, which by the early 20th century had been reduced to a semi-colony: the 1907 Anglo-Russian Convention had divided the country into foreign spheres, the Constitutional Revolution (1905–1911) had faltered, and World War I had brought occupation and famine despite Iranian neutrality.

Origins & rise

The Pahlavi state rose from the wreckage of Qajar Iran, which by the early 20th century had been reduced to a semi-colony: the 1907 Anglo-Russian Convention had divided the country into foreign spheres, the Constitutional Revolution (1905–1911) had faltered, and World War I had brought occupation and famine despite Iranian neutrality. In February 1921 Reza Khan, a brigadier of the Persian Cossack Brigade, marched 3,000–4,000 troops into Tehran in a coup, becoming commander-in-chief and then prime minister (1923). He crushed separatist movements in Gilan, Azerbaijan, Kurdistan, Khorasan, and Khuzestan, briefly toyed with declaring a Turkish-style republic, and on 12–15 December 1925 had the Majles depose the Qajars and crown him Shah — taking the dynastic name "Pahlavi," after the language of pre-Islamic Sasanian Persia.

History & key rulers

Reza Shah (r. 1925–1941) built a centralized, secularizing, authoritarian state: a modern conscript army, the Trans-Iranian Railway, state factories, a secular judiciary, mass education and the University of Tehran, the unveiling of women (kashf-e hijab, 1936), and in 1935 the formal request that foreigners call the country "Iran" rather than "Persia." His refusal to expel German nationals led to the Anglo-Soviet invasion of August 1941; Iran became the "Persian Corridor" for Lend-Lease aid to the USSR, and Reza Shah abdicated in favor of his 21-year-old son, Mohammad Reza Pahlavi (r. 1941–1979), dying in South African exile in 1944. The young Shah survived the 1946 Azerbaijan crisis (an early Cold War confrontation that forced Soviet withdrawal), a 1949 assassination attempt that produced constitutional amendments strengthening the crown, and the 1951–53 oil nationalization crisis, which ended when the CIA- and MI6-backed coup of 19 August 1953 overthrew Prime Minister Mohammad Mosaddegh. Thereafter the Shah ruled as an increasingly absolute monarch: the White Revolution (from 1963) brought land reform, women's suffrage, and literacy and health corps; oil revenues after 1973 financed a vast military build-up and megalomaniac projects, crowned by the 2,500-year celebration of the Persian Empire at Persepolis in 1971. The SAVAK secret police suppressed communists, liberals, and Islamists alike.

Government, religion & culture

Formally a constitutional monarchy with a Majles (and, after 1950, a Senate), Pahlavi Iran became in practice what critics called an "imperial dictatorship" — from 1975 a one-party state under the Rastakhiz Party. Twelver Shia Islam remained the state religion, but both shahs aggressively curtailed clerical power, promoting a secular Persian nationalism reaching back to Cyrus the Great. By 1979 the population was about 38 million, urbanizing fast but deeply unequal.

Peak & territory

The state's territory — about 1.65 million km², essentially modern Iran — was unchanged throughout, its "peak" measured instead in power: by the mid-1970s Iran was the pre-eminent military power of the Gulf and America's key regional ally, and in 1971 it seized the Gulf islands of Abu Musa and the Tunbs.

Decline & legacy

Falling oil income after 1977, inflation, corruption, repression, and the alienation of the bazaar and clergy fused into the Islamic Revolution. The Shah left Iran on 16 January 1979; the monarchy collapsed on 11 February, and an Islamic Republic under Ayatollah Khomeini was proclaimed on 1 April 1979, ending 2,500 years of Iranian monarchy. The exiled dynasty, led by Crown Prince Reza Pahlavi, remains a pole of opposition politics.
