Beginning on 28 December 2025, demonstrations erupted across multiple cities in Iran, amid nationwide unrest against the Iranian government and a deepening economic crisis. This event has been the largest uprising since the 1979 Islamic Revolution. The ensuing crackdown, carried out under Ali Khamenei's and senior officials' order for live fire on protesters, resulted in massacres that left tens of thousands of protesters dead, making them the largest massacres in modern Iranian history.
Initially sparked by frustration over record-high inflation, food prices, and currency depreciation, the protests quickly evolved into a broader movement demanding an end to the Islamic government.
