A Study of History is a 12-volume universal history by the British historian Arnold J. Toynbee, published from 1934–1961. It received enormous popular attention but according to historian Richard J. Evans, "enjoyed only a brief vogue before disappearing into the obscurity in which it has languished." Toynbee's goal was to trace the development and decay of 19 world civilizations in the historical record, applying his model to each of these civilizations, detailing the stages through which they all pass: genesis, growth, time of troubles, universal state, and disintegration.
