The 2021 Myanmar coup d'état began on the morning of 1 February 2021 when democratically elected members of Myanmar's ruling party, the National League for Democracy, were deposed by the Tatmadaw—Myanmar's military—which vested power in a stratocracy.
The Tatmadaw proclaimed a year-long state of emergency and declared power had been vested in Commander-in-Chief of Defence Services Min Aung Hlaing. It declared the results of the November 2020 general election invalid and stated its intent to hold a new election at the end of the state of emergency. The coup d'état occurred the day before the Parliament of Myanmar was due to swear in the members elected at the 2020 election, thereby preventing this from occurring. President Win Myint and State Counsellor Aung San Suu Kyi were detained, along with ministers and their deputies and members of Parliament.
