1. A Coalition Built on Grievances, Not on a Shared Vision
The revolution succeeded in its first phase because an extraordinary range of Iranians found common cause in opposing the Shah, even though they had almost nothing in common beyond that opposition. Oil revenues had funded a spectacular but uneven modernisation drive, and the benefits flowed unevenly, enriching a connected elite while displacing traditional merchants, artisans, and rural migrants crowding into cities. The secret police created a pervasive atmosphere of fear that alienated intellectuals, professionals, and religious figures alike. What the opposition lacked was a programme for what should come next, and that absence would prove decisive once the Shah was gone.
Why it matters: Understanding the coalition's internal contradictions explains why the revolution's outcome surprised so many of its own participants; the clerical faction did not simply inherit power but had to seize it from former allies.
