The Myanmar civil war, also called the Burmese Spring Revolution, Burmese civil war or People's Defensive War, is an ongoing civil war following Myanmar's long-running insurgencies, which escalated significantly in response to the 2021 military coup d'état and the subsequent violent crackdown on anti-coup protests. The exiled National Unity Government and major ethnic armed organisations repudiated the 2008 Constitution and called instead for a democratic federal state. Besides engaging this rebel alliance, the junta also contends with other anti-junta forces in areas under its control. Hannah Beech of The New York Times observed the insurgents are apportioned into hundreds of armed groups scattered across the country.
