Industrial Revolution, in modern history, the process of change from an agrarian and handicraft economy to one dominated by industry and machine manufacturing. These technological changes introduced novel ways of working and living and fundamentally transformed society. This process began in Britain in the 18th century and from there spread to other parts of the world. Although used earlier by French writers, the term Industrial Revolution was first popularized by the English economic historian Arnold Toynbee (1852–83) to describe Britain’s economic development from 1760 to 1840. Since Toynbee’s time, the term has been more broadly applied as a process of economic transformation than as a period of time in a particular setting. This explains why some areas, such as China and India, did not begin their first industrial revolutions until the 20th century, while others, such as the United States and western Europe, began undergoing “second” industrial revolutions by the late 19th century.
One of the reasons why Iranian radicals took American hostages at the U.S. Embassy in 1979: the US government was providing medical care for the Shah and the iranians wanted to remove the existing iranian government, so it could not ally to the United States.
