Because nobody has actually come in to talk truthfully and openly about what exactly history as a degree does for you I'm going to step up to the plate.
There's often a massive misconception that if you do history you are becoming a teacher or a historian or going to work in a museum.
History itself is fascinating to learn and you obviously know all of this because you say you love it. But a history degree is quite different from say an engineering degree in the respects of what it provides you.
An engineering degree (not that I know much, if anything, just saying) probably provides you with set knowledge that you can apply to everyday jobs because it's engineering.
History is different in this respect, knowing about history can sometimes be useful, sometimes interesting to tell others but in the job world not that important unless you are doing a history orientated job. Sounds like I've just slammed history, but there's a reason why I am doing it.
It's the skills you gain not the knowledge you inherit when it comes to employability for history.
History, when studied at a good level requires candidates to possess skills that range from impressive analytical skills to clear, open and expressive oral and written skills. In addition to this you find that they excel in research and have an impressive ability to read between the lines of texts, interpret and judge accountability of sources. (This is why so many law firms look for history graduates, because they gain such important skills which are invaluable for a career in law).
There are many more, but I'm sure if I go on about them all you will just get bored and I'm sure you get the idea. Gordon Brown, George Osborne are two prime examples of those with history degrees who also left what you would consider the obvious route. I know it's anecdotal but I know of somebody else who completed a history degree and is doing well at a financial firm.
History literally opens you up to a whole variety of things, yes including businesses and management and accounting, whilst less so, it's a perfectly viable open door. However consider law, politics, professional research/ analysation, library work, sales roles, company Human Resources/ team leaders/ team members/ representatives and much, much more which I will happily discuss should you PM me.
Doing history demonstrates skills that can impress employers in a tough and rigorous 'traditional' subject. Those who assume the only jobs available are teaching.
Maybe history isn't for you, but I hope that helps. Got kind of sick of all the bad information posted on this thread.
