“Coup d’etat”

Supposedly, XI avoided a coup by hours before purging the military leadership.

“Coup d’état (often shortened to coup) is a French term that literally translates to “stroke of state” or “blow to the state” (from coup meaning “strike” or “blow,” and d’état meaning “of state”).
It refers to the sudden, illegal, and usually violent seizure of a government’s power by a small group of people—most often elements within the military, security forces, or political elites—aiming to overthrow the existing leadership or government.”
