The thing that caused the Industrial Revolution was a combination of 6 things. Coal extraction, steam power, industrial production, iron smelting, agricultural production and the railroads. The most important factor was coal extraction, none of the other things would be there. Without coal there would be nothing to power the machines, so no industrial production. No steam power, so no railways and no iron smelting so no agricultural production. Although coal extraction may be the most important that does not mean that all the other aren’t. Agricultural production created opportunities for people to go and work in factories, boosting industrial production which gave a reason for steam power and railways. This made it so that goods could go from place to place in a quicker fashion. More people could extract coal, making a cycle in which would make a huge revolution completely changing people’s lives.
