A revolution is a significant change that usually occurs in a relatively short period of time. It may be the result of a rebellion carried out with the intention of creating an entirely new form of government or any new cultural/social/technological paradigm. Examples are the Industrial Revolution, a major shift of technological, socioeconomic, and cultural conditions; the American war against colonial Britain; the Bolshevik overthrowing of the Russian monarchy to attempt to create a communist society; and the attempt by the Khmer Rouge to start Cambodian history anew.
