Translation:There was a recession in Ireland and we did not have money.
"War" usually takes an article, because it has a defined beginning and end, and you are usually referring to a specific war - "a war" or "the war". You can also refer to it in the plural - "wars". "War" can also be an ongoing state, in which case it can be used without an article. The same is true for "recession" - you can refer to "a recession", to "the recession" or "recessions", and you can pinpoint the beginning and end of "a recession". "peace", on the other hand, is usually the gaps in between wars or other conflicts. We don't refer to the periods between different wars as "peaces", and, while you can refer to a particular period of peace (an ongoing state) as "the peace", it's more likely to be used as an adjective ("peace time").
