The Industrial Revolution also known as the First Industrial Revolution was a period of global transition of the human economy towards more widespread efficient and stable manufacturing processes that succeeded the Agricultural Revolution starting from Great Britain and spreading to continental Europe and the United States that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines; new chemical manufacturing and iron production processes; the increasing use of water power and steam power; the development of machine tools; and the rise of the mechanized factory system. Output greatly increased and the result was an unprecedented rise in population and the rate of population growth. The textile industry was the first to use modern production methods: 40 and textiles became the dominant industry in terms of employment value of output and capital invested.
