THE BRITISH ARE COMING!
Great Britain, the leader of Industrialization was also the leader of Imperialism.
Britain had started imperialistic policies by the 1600s, forming colonies in the new world and had built a trade network in Asia and India by the 1700s.
By the 1800s, Britain gave some of its colonies self rule (Canada, Australia) but tightened its control on other areas.
Britain also faced competition from other industrialized countries by the mid 1800s and was trying to maintain its economic superiority.
