(Railways, Agricultural Productions, Industrial Production, Iron Smelting, Coal Extraction, Steam Power)
I think all five of these contributed in causing the Industrial Revolution, but the most important was coal extraction. Coal extractions helped with the railways, steam power, and the industrial productions. If coal wasn’t used to smelt iron, the railways wouldn’t be as fast and efficient as they were, and the industrial production would be delayed rather than getting things back and forth fast on steam power. The industrial production (which were mostly iron machines and iron was smelted by coal) helped with agricultural Culture too, because the machines made farming and growing crops a lot easier. I think if coal extraction had not been introduced during that time, some of the most famous machines would not have been established.
