Contingency of Structures: Triggers and the Social Geography of Revolutionary Episodes in Iran 2017–2022
What drives the uneven geographic spread of revolutionary episodes? While structural approaches emphasize pre-existing fault lines, contingency approaches highlight emergent processes. We synthesize these perspectives, arguing that specific triggers shape a revolutionary episode's social geography by activating certain fault lines while leaving others dormant. Through a comparative analysis of three revolutionary episodes in Iran (2017–2022), each with a distinct trigger, we demonstrate how different triggers shape patterns of contention.
