The Industrial Revolution occurred in three stages:
1. Agricultural revolution (1700 – 1800)
2. Industrial revolution (1800 – 1950)
3. Services revolution (1950 – )
Usually when people use the term "Industrial Revolution" they mean only the "industrial" part of the Revolution (the second/middle part). But the above version give a more complete picture.
The Industrial Revolution marked the transition from the Agricultural/Traditional Age to the Industrial/Modern Age. So people jump to the conclusion that modernisation means industrialisation. Though industrialisation forms the core of modernisation, it is not its only component. As seen above, the agricultural revolution is a pre-condition for industrialisation.
