Final answer:
The British Empire used technology, military conquest, and socio-economic control to implement and maintain imperialism, particularly in India.
Step-by-step explanation:
The British Empire embodied imperialism via technological advances, military conquest, and socio-economic control. Through the Second Industrial Revolution, technology such as advanced weaponry and communication systems, coupled with medical advancements, allowed European empires to dominate globally. The British administration established vast bureaucracies to govern the colonies, using economic and military might to secure markets and resources, as epitomized in India where a small number of British officials ruled millions.
Military conquests and strategic positioning, like Great Britain's competition with Russia over Afghanistan, were aimed to protect imperial interests and prevent encroachment by other powers. As other nations industrialized, there was an increasing drive to control territories for raw materials, resulting in the justification of empire building as a necessary means for economic survival and the spread of perceived cultural superiority.
