Concept:The term "Industrial Revolution" was first introduced by English historian Arnold Toynbee to describe Britain's rapid industrial changes between 1760 and 1820.
Explanation:Arnold Toynbee (1852–1883) was an English economic historian.
He was the first to use the phrase "Industrial Revolution" in English to characterise the transformation from an agrarian, handicraft economy to one dominated by industry and machine manufacturing.
The term originally described British industrial development from 1760 to 1820 (later extended to 1830).
Other historians like J.A. Blanqui, T.S. Ashton, and R.H. Tawney contributed to economic history but did not coin this specific term.
Toynbee's work popularised the concept, which now refers to the broad technological, socioeconomic, and cultural changes that began in Great Britain.
