How did inventions lead to an increase in Imperialism?

The Industrial Revolution led to imperialism in ways such as creating the demand for raw materials, which would be turned into products in factories, and providing the means to transport those raw materials with inventions such as the steam engine.

These new industrialized nations needed more raw materials to fuel their mass production and population growth. In order to maximize the countries profits, these industrialized nations went out to find nations that they could exploit natural resources and cheap labor from thus leading to imperialism.

the mother countries succeed in doing that by using the colony's natural resources, facilities in a colony, they do not take good care of these facilities, causing them to fail. this has had negative and positive effects on the people of africa, they then governed through direct or indirect rule depending on the country.
