Industrialization: the large-scale introduction of manufacturing, advanced technical enterprises, and other productive economic activity into an area, society, country, etc. (Dictionary.com)
Imperialism: a policy of extending a country's power and influence through diplomacy or military force. (Dictionary.com)
The common theme between industrialization and imperialism is expansion. In both cases, a country or society is looking to build on what they have. Industrialization is the expansion of industry, such as: factories, manufacturing, workforce, and products. Imperialism is the expansion of your empire. Britain is most well-known for their imperialist endeavours in Africa, Asia and North America. Britain had so many colonies around the world that it was said “the sun never sets on the British Empire”.
The expansion of industrialization is what largely impacted imperialism. As countries started to expand their industries, they built better weapons and ways of transportation. This allowed well developed countries to easily take over small nations that had large supplies of raw materials. As industry expanded, there was a greater need for space, resources, and a workforce. All of these could be provided by other nations that had not developed industry. Imperialism was a way of taking over colonies while expanding their resource base.
