It's a Coup!

Although the coup d'état has featured in politics since antiquity, the phrase is of relatively recent coinage;[5] the Oxford Dictionary identifies it as a French expression meaning a “stroke of State”. Prof. Thomas Childers, of the University of Pennsylvania, indicates that the English language's lacking a word denoting the sudden, violent change of government derives from England's stable political traditions and institutions. French, German and U.S. history are coloured with such politico-military actions. Who will reign supreme???
