Teen Gothic

So basically I am a history buff and also a goth and I was wondering why is this subculture and genre of music called "goth". Cause historically it referred to an actual race of people instead of a music-based subculture. I looked arpund the sub reddit and didn't really find a straight answer. So my question basically is why are the genre and subculture called "goth" and what are its origins Edit: I know this is a dumb question but it has been bugging me for a while
