The agricultural revolution in Britain was very important, if not the most important factor that led to the industrial revolution.
The reason for this is that with the agricultural revolution, the production on the farmlands increased significantly, and that trend was constantly going upwards. That led to a situation where there was much more production than what the country needed, so it had to be traded. But the trade of the crops was still limited, thus something new was needed, something that will enable the manufacturing of the goods, so that they can be preserved better and last longer, so that they can be traded further away. That economic pressure, led to multiple inventions, which resulted in the development of the industry, thus having the start of the industrial revolution.
