In the last century the best development in the field of history has been the addition to the activities that are available to the historians. Researching, reading, writing, lecturing history was all there was to it since Herodotus' time. Then came archeology. Now people are doing history. Re-enactors are not just writing or talking but are doing history. Civil War re-enactments, Renaissance Fairs, and Medieval evens are just a few of the activities that now happen. This came from the grassroots not the professionals.
