The answer rests in what kind of BA you are taking- BA in liberal arts setting or BA from the traditional offering perspective.
If you are taking BA in Liberal arts context, so if you are pursuing BA in History in a non liberal arts setting, you will just be diving deep into history, history and history all your years without understanding the other disciplines.
If you pursue a BA in History in liberal arts setting, you will develop a deep understanding of history and at the same time you will have adopted all the other transferable skills. So, you will be a history  major who will be creative, who would be able to solve complex problems, who will be a great communicator. So that is the difference and hence there are implications in the job market.
