It was my impression that the aborted war between the Klingons and the Federation seen in "Errand of Mercy" was the first time the superpowers had come into open conflict. But have there been any references in Trek to a previous Klingon/Federation war?
FASA came up with the "Four Years War" between the Federation and Klingons (2194-2198) for their RPG games in the 80's, fanzines have speculated that such a war may have taken place, and now Discovery may be featuring a Klingon/Federation war of their own in 2256 - but am I right that they were added to the history of Trek after the fact?
