Coup d'état

A coup d'état or simply coup is the sudden and unlawful overthrow of a government by a small group within the state establishment.

In 2372, Vice Admiral James Leyton attempted a military coup of the Federation due to his view that the civilian government was not doing enough to prepare for a possible conflict with the Dominion. He was stopped before he could seize control by Captain Benjamin Sisko and the imminent arrival of the USS Defiant with evidence of his plot. 


 * In the Pendragon universe, Leyton's coup was not averted and he took control of the Federation leading the Federation Civil War.

In 2373, a coup d'état led to the collapse of the Thallonian Empire. (' novel: ')
