Since the last week of December 2025, Iran has seen its largest uprising in years. The immediate cause was the collapse of the national currency, the rial. Shopkeepers in Tehran’s Grand Bazaar shut their stores in protest, sparking a nationwide demand for political change. What started as an economic complaint quickly escalated into a direct challenge to the theocracy. The unrest spread to at least 78 cities and over 200 locations by early January 2026. This movement, met with harsh repression, has tested the regime’s stability.
