What is Applied History?
Perhaps the folks at the Belfer Center describe it best:
Applied history is the explicit attempt to illuminate current challenges and choices by analyzing historical precedents and analogues. Mainstream historians begin with a past event or era and attempt to provide an account of what happened and why. Applied historians begin with a current choice or predicament and attempt to analyze the historical record to provide perspective, stimulate imagination, find clues about what is likely to happen, suggest possible policy interventions, and assess probable consequences. It might be said that applied history is to mainstream history as medical practice is to biochemistry, or engineering to physics. But that analogy is not quite right, as in the realm of science there is mutual respect between practitioners and theorists. In the realm of policy, by contrast, one finds a culture of mutual contempt between practitioners and historians. Applied history is an attempt to address that.
