The research skills you get from a history degree stand you in good stead for any research-based job, and anything that involves bringing together a lot of resarch/data to come to come up with a coherently written and well argued report. This can apply to quite a wide range of sectors. With degrees like history, politics etc for most people it'll be about developing transferable skills and being able to demonstrate to employers that you'll be able to put them to good use in work situations. Comparatively few people will either remain in academia or get a job in a sector in which history as an academic discipline will be directly relevant, but it certainly increases your employability. Afterwards, how well you do with your career will depend on being able to demonstrate once in actual employment that you've actually gained genuine skills which you're able to put to good use.
