Change and continuity
Change and continuity is a classic dichotomy within the fields of history, historical sociology, and the social sciences more broadly. The question of change and continuity is considered a classic discussion in the study of historical developments. The dichotomy is used to discuss and evaluate the extent to which a historical development or event represents a decisive historical change or whether a situation remains largely unchanged. A good example of this discussion is the question of how much the Peace of Westphalia in 1648 represents an important change in European history. In a similar vein, historian Richard Kirkendall once questioned whether FDR's New Deal represented "a radical innovation or a continuation of earlier themes in American life?"
