In the 1800s, industrial towns emerged, attracting the existing surplus of agricultural workers in rural areas, who moved to cities and started to work in factories that had implemented massive production systems. 
Such factories were, in turn, located next to suppliers and raw materials, for example, next to energy production plants. Moreover, for the subsequent commercialization of their products and services, factories needed to be easily reacheable by using cheap means of transport (railroads, ports, etc). <u>The existence of the mentioned facilities triggered the establishment of factories and companies in certain locations, that gave rise to the development and success of industrial towns. </u>
