European countries expanded their colonial empires between 1870 and 1914, mainly in Africa and Asia. There were several factors driving this imperial expansion. European countries had advanced economies, powerful armies, and new technologies that allowed them to take over territories without organized states. They also faced economic pressures at home to find new lands, resources, and markets abroad to absorb surplus populations and goods. Powerful figures like British businessman Cecil Rhodes advocated for imperialism as a solution to issues like unemployment and overpopulation in European countries. Europe's growing technological advantages, industrial production capacity, and populations led them to seek new areas for investment and trade, fueling the age of global imperialism.
