How to translate the following
How would I translate "A Leftist Revolution" in German? Without putting it in German, I thought it would need to be along the lines of "A Revolution of the Left" roughly speaking. Eine Revolution vom Linke - something like that?
It depends on what you really want to express. What does your sentence refer to?
Several possibilities (only my suggestions):
It's a revolution in a country, started by the political left: "Eine Revolution von links".
It's a revolution within a "leftist movement": "Eine Revolution bei den Linken".
I think in order to know how to translate your headline properly, we have to know what you are describing.
