What conflicts were there between France and Sweden pre 30 years war?

by sufficiency

This may be a silly question, but I encountered this polanball comic (read it first if you don't mind) http://i.imgur.com/mxzUpoS.png and I have some trouble understanding the first part of it.

Now, I know a little bit about the 30 years war and Sweden/France's participation. I do not know the conflicts between the two countries prior to the 30 years war, which this comic suggests. Can anyone enlighten me on this?

Thanks.

I think this doesn't reference France vs Sweden but rather Catholics vs Protestants. France was Catholic and just out of a brutal civil war between Protestants and Catholic, yet it joined the Protestant side during the 30 Years War because the Habsburgs were a bigger threat to French interests.
