Historic recurrence is the repetition of similar events in history. The concept of historic recurrence has variously been applied to overall human history (e.g., to the rises and falls of empires), to repetitive patterns in the history of a given polity, and to any two specific events which bear a striking similarity.
Hypothetically, in the extreme, the concept of historic recurrence assumes the form of the Doctrine of Eternal Recurrence, which has been written about in various forms since antiquity and was described in the 19th century by Heinrich Heine and Friedrich Nietzsche.
While it is often remarked that "history repeats itself", in cycles of less than cosmological duration this cannot be strictly true. In this interpretation of recurrence, as opposed perhaps to the Nietzschean interpretation, there is no metaphysics. Recurrences take place due to ascertainable circumstances and chains of causality. An example is the ubiquitous phenomenon of multiple independent discovery in science and technology, described by Robert K. Merton and Harriet Zuckerman. Indeed, recurrences, in the form of reproducible findings obtained through experiment or observation, are essential to the natural and social sciences; and, in the form of chance observations rigorously studied via the comparative method, are essential to the humanities.
G.W. Trompf, in his book The Idea of Historical Recurrence in Western Thought, traces historically recurring patterns of political thought and behavior in the west since antiquity. If history has lessons to impart, they are to be found par excellence in such recurring patterns.
Historic recurrences of the "striking-similarity" type can sometimes induce a sense of "convergence", "resonance" or déjà vu.
Ancient western thinkers who had thought about recurrence had largely been concerned with cosmological rather than historic recurrence (see "eternal return", or "eternal recurrence").
