This one lists all the wars mentioned in Star Trek, or at least all the ones that I can think of or find in a serach of scripts, encyclopedias, etc. There
is a degree of judgement in what to call a war and what not to. For instance, I don't class the Ansata situation as fighting a war because they were terrorists
not soldiers. Yet I do include the Cardassian-Bajoran conflict because the Bajorans must have had some sort of government to begin with, and so the initial invasion
at least would certainly be a proper war.
Where a specific name for the war was given, I have used that. Elsewhere I have used the format "X-Y war", where X and Y are the names of the
combatants in alphabetical order. Sometimes I have included a modifier such as "civil war" or "planetary war" where it seemed appropriate.
The episode name listed here is the first episode in which the war is mentioned, and is not necessarily the most prominent mention.

Sisko's refers to "the LAST Federation-Tzenkethi war" implies that there have been at least two if not more such conflicts.45 Details are few, but since Sisko fought in the war whilst a first officer on the USS Okinawa, the last war would probably have taken place around 2365-69.46 |
