Why do I need Applied History for a degree in writing?

Along with my writing classes, I’m taking Introduction to Marketing and Applied History.
The marketing I get. It makes sense. Even if I hire someone to market for me, I should know the basics.
Why in the crap do I need to learn how to write an effective research question, how to think like a historian, or about something that happened over one hundred years ago.
Hello, I’m writing fiction. While what I’m writing may be someone’s reality, it’s not mine.
So again, WHY?
