The manufacturing industry that most employed workers was the textile industry.
In the context of the Industrial Revolution, the textile industry developed the fastest. For the first time, clothing implements were produced on a large scale. In this context, England has become the largest supplier of fabric to the world, demanding a lot of manpower in the factories. Other countries that developed their textile industry also demanded a lot of labor. To this day, the textile industry demands many employees.
