One element of imperial history is that events tend to be seen as caused by extraordinary personalities acting on one another without showing us the social roots and contexts of those actions. For example, many of the great discoveries and inventions we are taught about in elementary and high school were being pursued by many people at once, but the individual who received the patent is described as a lone explorer rather than part of a group effort. Rosa Parks didn't get tired one day and start the Montgomery bus boycott. She was a trained organizer, and her role, as well as the time and place of the boycott, was the result of careful planning by a group of civil rights activists. Just as medicinal history must restore individuality to anonymous masses of people, it must also restore social context to individuals singled out as the actors of history.
