Although environmental history has emerged as a distinct historical field only since the late 1960s, it has a long ancestry. The idea that human society (and hence history) is affected by physical environment can be traced back as far as ancient Greece; ideas of climatic and geographical determinism were also widespread in the eighteenth and nineteenth century Europe. Modern environmental history has, however, been shaped by the development of historical geography and agrarian history, by attempts to establish a more scientific basis for history, and, more recently, by growing concern about environmental degradation. Modern environmental history can also be understood as part of a wider reaction against an older history of nations, states and “great men and women”. Byzantine studies too, have not avoided this “environmentalism”. Since the early 1980s various studies concerning aspects of historical geography of the Byzantine period have appeared.
