Myanmar Civil War: Timeline & Latest Developments

Myanmar’s civil war began on February 1, 2021, when the Tatmadaw detained President Win Myint and State Counsellor Aung San Suu Kyi, declared a state of emergency, and installed the State Administration Council (SAC) under Senior General Min Aung Hlaing, citing unproven fraud allegations over the November 2020 election Aung San Suu Kyi’s National League for Democracy had won decisively. Within days a nationwide Civil Disobedience Movement, led first by striking healthcare workers, drew hundreds of thousands of participants, and the military’s response was immediate and lethal: the Assistance Association for Political Prisoners (AAPP) documented 884 killings by security forces tied directly to the protests and crackdown by the end of that first year alone. As peaceful resistance met escalating violence, the ousted lawmakers formed the National Unity Government (NUG) on April 16, 2021, and on May 5, 2021, the NUG stood up the People’s Defence Force (PDF), a date most trackers treat as the start of the war’s armed phase.

The resistance that followed was never a single movement. The PDF’s newly formed local militias fought alongside, not under, Myanmar’s older ethnic armed organizations (EAOs) such as the Karen National Liberation Army (KNLA), Kachin Independence Army (KIA), and Arakan Army (AA), which had contested the state’s borderlands for decades before the coup and brought their own leadership, territory, and goals to the fight. The KNLA struck the war’s first military target on March 27, 2021, killing 10 Tatmadaw soldiers, while the KIA and other groups opened their own fronts through 2021 and 2022. By late 2022 the Arakan Army had struck an informal ceasefire with the junta in Rakhine State, using the pause to expand its own administration rather than join the PDF’s fight elsewhere, evidence of how differently each armed group read its own local situation. The UN estimated in March 2023 that 17.6 million people needed humanitarian assistance and 1.6 million had already been displaced, a toll driven as much by scattered, low-intensity fighting nationwide as by any single campaign.

That changed on October 27, 2023, when the Myanmar National Democratic Alliance Army, Ta’ang National Liberation Army, and Arakan Army, together the Three Brotherhood Alliance, launched Operation 1027 across northern Shan State. The offensive captured more than 100 junta positions within two weeks and seized Laukkai, the Kokang region’s capital, by January 2024. A China-brokered Kunming ceasefire collapsed within a day under renewed junta airstrikes, and by June 2024 the alliance had resumed fighting. The momentum spread well beyond Shan State: thousands of Tatmadaw soldiers surrendered without a fight in February 2024, the KIA opened its own Kachin State offensive in March, the KNLA came close to seizing the Myawaddy border crossing with Thailand in April before withdrawing to avoid civilian harm, and the Arakan Army took a second regional command headquarters at Ann in December, having already secured the entire Rakhine-Bangladesh border that same month. By year’s end, independent trackers estimated the junta held fewer than half of Myanmar’s 330 townships for the first time since the coup.

A magnitude 7.7-7.9 earthquake struck near Mandalay on March 28, 2025, killing at least 3,770 people by the junta’s own count and as many as 4,549 by independent tracking, and briefly paused offensives on both sides. The pause did not hold: monitors and resistance groups reported continued junta airstrikes through the SAC’s own declared ceasefire window, and by mid-2025 the junta was back on the offensive. Backed by fresh China-brokered truces with individual EAOs, Tatmadaw forces retook Kyaukme in October 2025 as the TNLA withdrew from Mogok and Mongmit and the MNDAA fully left Lashio under Chinese pressure, a partial reversal of Operation 1027’s gains even as the Arakan Army kept advancing in the west. On July 31, 2025, the SAC formally dissolved itself, folding its powers into a new council still chaired by Min Aung Hlaing, a restructuring critics called consolidation rather than any real transition.

That consolidation continued into 2026. The junta staged a three-phase general election from December 2025 to January 2026 that the military-aligned Union Solidarity and Development Party won by a wide margin, a result the NUG and international observers said could not be free or fair given active fighting and restricted access across dozens of townships. Min Aung Hlaing was sworn in as president on April 10, 2026, converting direct military rule into a constitutional form without changing who holds power. Resistance forces consolidated too, though not without friction: the NUG and four major EAOs, the Karen National Union, Kachin Independence Organisation, Karenni National Progressive Party, and Chin National Front, formed the Steering Council for the Emergence of a Federal Democratic Union (SCEF) on March 30, 2026, even as clashes between rival factions, such as the MNDAA’s capture of Kutkai from a TNLA-aligned force that same month, underscored that the anti-junta side remains a coalition of separate armies, not a unified command. Separately, the ICJ opened merits hearings in January 2026 on The Gambia’s genocide case over the military’s 2016-2017 campaign against the Rohingya, a case predating this civil war but bearing on the same institution’s broader conduct, with a ruling expected later in 2026. As of mid-2026, ACLED puts total conflict deaths above 100,000 and AAPP counts 9,027 civilians and activists killed by the junta specifically, while UNHCR records roughly 3.8 million internally displaced and 1.62 million Myanmar-origin refugees abroad, a toll the UN’s own 2026 response plan says it can only afford to address for 4.9 million of the 16.2 million people it estimates are in need.
