<p>Why double major? You have a humanities requirement. Use it to take the courses that interest you. You may find that to be sufficient for you curiosity in history. </p>
<p>You can also satisfy your desire to learn by reading and studying on your own, outside the classroom (usually during the summer or other school breaks as you will be quite busy during the term) and after you graduate.</p>
<p>I was a manager (now retired) at a large aerospace engineering company and was always looking for the most prepared applicants. That meant that they took more than the minimum required classes for their degree in engineering. I usually found that people who double majored had the minimum classes for their degree unless the two degrees were almost the same. They, therefore, moved down considerably in my consideration for employment as I had many more resumes with people who had more engineering classes (and the same or just as good a school, and just as good a GPA).</p>
