A coup d'état, also known as simply a coup, is the process in which a group overthrows governments and take control from them. Throughout Earth history, there has been several coups.

2006: Ladon Radim of the Genii plotted to overthrow Cowen and take control of the Genii. To this end, he lured Cowen and his elite guard to M6R-867, an abandoned world where he planted a nuclear weapon using the promise of Puddle Jumpers and some of the Atlantis team. After learning that Doctor Carson Beckett could save some of the people he sent as "hostages" to Atlantis including Ladon's own sister, he let the Atlantis team go. The plan worked and the nuclear weapon killed Cowen and all of his men. As so many of Cowen's followers were killed, the rest laid down their weapons and let Ladon take over in what was billed a "bloodless coup" as it didn't happen on the Genii homeworld.
