In January and February 1970, in the Iraqi city of Najaf, an exiled Iranian cleric delivered a series of lectures to a small circle of students that would, within a decade, become the governing doctrine of an entire nation. Ruhollah Khomeini had been expelled from Iran in 1964 after publicly denouncing the Shah's government, and by 1970 he had spent years in exile developing an argument considerably more radical than most of his fellow Shia jurists were prepared to make: not merely that clerics could advise or morally check a ruler, the position most prior Shia jurisprudence had settled on, but that a qualified jurist should hold direct political authority over the state itself, standing in for the Twelfth Imam during his occultation.
Khomeini's lectures were published that same year as the book Islamic Government, sometimes translated as Governance of the Jurist, and for most of the following decade they remained a minority position even within the ranks of clerics opposed to the Shah, many of whom favoured a more limited advisory role for religious authority over direct clerical rule. What changed the doctrine's fortunes was not further argument but the Iranian Revolution itself: when the Shah's government collapsed in 1978 and 1979, Khomeini returned from exile to a level of popular support no other opposition figure could match, and the new constitution drafted in the revolution's immediate aftermath wrote his doctrine directly into Iran's founding law. Article Five names velayat-e faqih the state's governing principle; Articles 107 through 112 spell out the Supreme Leader's specific powers over the president, the judiciary, the armed forces, and legislation passed by the elected Majlis.
What is easy to miss, reading the doctrine only from its lecture-hall origin, is how much institutional machinery had to be built to turn a jurisprudential argument into a functioning government: an Assembly of Experts to select and, in principle, remove the Supreme Leader; a Guardian Council empowered to vet candidates for president and parliament and to strike down legislation on religious grounds; a judiciary appointed through the Supreme Leader's own office rather than through the elected government. Khomeini's 1970 lectures supplied the doctrine's theoretical justification; the 1979 constitution supplied the machinery that let a theory drafted for a small circle of exiled students become, within less than a decade, the operating structure of an entire modern state.
