What word would I use when describing two opposing sides in a war?

Assuming I want to refer to them in a manner similar to the following:

Comparing/contrasting the ____'s of the war.

Using opposing sides lacks eloquence in my opinion. I'm also open to rewording the above so that opposing sides is not needed.

    I would not call opposing sides lacking in eloquence.

  • "Contrasting the opposing sides of the Peloponnesian war" seems to be a clunky title for a formal paper to me. Oct 20 '11 at 0:52

    Really? I would say it sounds quite good.

    You could just say the Athenians and the Spartans.

I like this one: belligerents.

    Looking further, en.wikipedia.org/wiki/Belligerent indicates that this is actually the UN/internationally accepted word. Oct 20 '11 at 12:39
  • In (for example) histories of WWII, the allies are sometimes referred to as "co-belligerents". Oct 20 '11 at 13:50
  • @mickeyf I thought that "co-belligerent" was used to describe nations that are not allied with each other, but share a common enemy [like Finland and Germany vs USSR]

equally include both sides in any kind of, well, opposition.

    Comparing the opponents of the war is ambiguous, though. Be careful that it doesn't come across as meaning Comparing those who oppose the war.

    @drɱ65δ: good point. 'Opponents to the war' is not ambiguous but it is for the meaning you give. 'Opponents in the war' would be ambiguous for the original question.

    Opponents seems too mild a word for war. Like they could playing table tennis.

    Combatants seems to imply the actual individuals involved in front-line fighting, as say opposed to the politicians who stand behind them. Oct 20 '11 at 12:38

Adversaries is another option.


You can use "belligerents" as in...

Comparing and contrasting the belligerents of the war.

You can also use factions, but that usually connotes something other than nation-states fighting.

Comparing and contrasting the warring factions.


Some options are the following ones:

  • opposing forces
  • opposing armies
  • participants
  • FWIW: OpFor (short for "opposing force") is used in wargames to designate the enemy combatants being, um, simulated.

Another term you could use is "opposing factions."

  • I think "faction" suggests the two sides are more closely related than, say, two countries, so it's applicable only in a subset of cases.

I'm a bit late to this thread and new to this site. I hope I'm not breaking any rules by reviving this subject....

foes, adversaries, partisans

  • Word request answers require citations from reputable dictionaries.
