Where does the “darkwave” style come from?

Hey this is a question that I asked myself 2 days ago, I wonder where darkwave comes from even if I know that it is part of gothic culture if I'm not saying anything stupid, but put aside Since when did it come into existence, is it an inspiration from 80s synthpop music, we hear a lot of 70s guitar in certain tracks

It’s up to you to tell me your vision of things, where does darkwave come from?
