The 1991 Iraqi uprisings were ethnic and religious uprisings in Iraq led by Shi'ites and Kurds against Saddam Hussein. The uprisings lasted from March to April 1991 after a ceasefire following the end of the Gulf War. The mostly uncoordinated insurgency was fueled by the perception that Iraqi President Saddam Hussein had become vulnerable to regime change. This perception of weakness was largely the result of the outcome of the Iran–Iraq War and the Gulf War, both of which occurred within a single decade and devastated the population and economy of Iraq.Within the first two weeks, most of Iraq's cities and provinces fell to rebel forces. Participants of the uprising were a diverse mix of ethnic, religious and political affiliations, including military mutineers, Shia Arab Islamists, Kurdish nationalists, and far-left groups. Following initial victories, the revolution was held back from continued success by internal divisions as well as a lack of anticipated American and/or Iranian support. Saddam's Sunni Arab-dominated Ba'ath Party regime managed to maintain control over the capital of Baghdad and soon largely suppressed the rebels in a brutal campaign conducted by loyalist forces spearheaded by the Iraqi Republican Guard.

During the brief, roughly one-month period of unrest, tens of thousands of people died and nearly two million people were displaced. After the conflict, the Iraqi government intensified a prior systematic forced relocation of Marsh Arabs and the draining of the Mesopotamian Marshes in the Tigris–Euphrates river system. The Gulf War Coalition established Iraqi no-fly zones over northern and southern Iraq, and the Kurdish opposition established the Kurdish Autonomous Republic in Iraqi Kurdistan.
