In regard to nature, events apparently the most irregular and capricious have been explained and have been shown to be in accordance with certain fixed and universal laws. This have been done because men of ability and, above all, men of patient, untiring thought have studied events with the view of discovering their regularity, and if human events were subject to a similar treatment, we have every right to expect similar results.
Contrary to Buckle’s dream, the 19th-century historian with greatest influence on methods became Leopold von Ranke in Germany. He limited history to “what really happened” and by this directed the field further away from science. For Ranke, historical data should be collected carefully, examined objectively and put together with critical rigor. But these procedures “are merely the prerequisites and preliminaries of science. The heart of science is searching out order and regularity in the data being examined and in formulating generalizations or laws about them.”
As Historians like Ranke and many who followed him have pursued it, no, history is not a science. Thus if Historians tell us that, given the manner in which he practices his craft, it cannot be considered a science, we must take him at his word. If he is not doing science, then, whatever else he is doing, he is not doing science. The traditional Historian is thus no scientist and history, as conventionally practiced, is not a science.
Today, most historians begin their research process in the archives, on either a physical or digital platform. They often propose an argument and use their research to support it. John H. Arnold proposed that history is an argument, which creates the possibility of creating change.
Environmental historian William Cronon proposed three ways to combat bias and ensure authentic and accurate narratives: narratives must not contradict known fact, they must make ecological sense (specifically for environmental history), and published work must be reviewed by scholarly community and other historians to ensure accountability.
These are approaches to history; not listed are histories of other fields, such as history of science, history of mathematics and history of philosophy.
Military history concerns warfare, strategies, battles, weapons, and the psychology of combat.
The history of religion has been a main theme for both secular and religious historians for centuries, and continues to be taught in seminaries and academe. Leading journals include Church History, The Catholic Historical Review, and History of Religions. Topics range widely from political and cultural and artistic dimensions, to theology and liturgy.
Cultural history replaced social history as the dominant form in the 1980s and 1990s. It typically combines the approaches of anthropology and history to look at language, popular cultural traditions and cultural interpretations of historical experience. It examines the records and narrative descriptions of past knowledge, customs, and arts of a group of people. How peoples constructed their memory of the past is a major topic. Cultural history includes the study of art in society as well is the study of images and human visual production (iconography).
