Pretty much exactly what @Fiddle_Playing_Creole_Bastard said – especially if you’re looking to do something with history afterwards, and not go into a completely different field in which you don’t utilize most of what you learn (not talking about research skills, but like.. knowledge of how the Black Plague was directly responsible for sumptuary laws – not really something the boss at your new real estate firm or whatever is really going to care about). You can become a teacher, work in a museum, teach, help create the textbooks, teach, become an archivist, teach, or go into (as I am) historic preservation. There are occasionally some jobs consulting for the private or public sphere, like for various writers or something, but I’m honestly not sure how common those are, and I’d imagine you often have to already have an established career as a historian for people to want to hire you on the side as a consultant. Look here for careers as a historian, and here for how to put a bachelors to good use. And Bastard’s definitely right about the advanced degrees – they’re becoming more and more required for all fields, not just history, but especially since history is such an academic field, they kinda want you to spend lots of time in, you guessed it, academia.
@Fiddle_Playing_Creole_Bastard Is it too late to change your major?
