During the agricultural revolution the invention of machinery led to a decrease in the number of workers required on farms. Unemployed people needed to move to find work. The industrial revolution and the mechanisation of industrial processes meant that goods could be produced in greater quantities and more cheaply. Factories were built in areas with access to raw materials (particularly coal and water) and transport (by road and water - notably canals). Manchester became a centre for the production of cotton goods, new factories were built and people moved to Manchester because work was available.
