 Industrialisation, however, dramatically increased European demand for Asian raw materials; and the severe Long Depression of the 1870s provoked a scramble for new markets for European industrial products and financial services in Africa, the Americas, Eastern Europe, and especially in Asia (Western powers exploited their advantages in China for example by the Opium Wars).This resulted in the so-called "New Imperialism", which saw a shift in focus from trade and indirect rule to formal colonial control of vast overseas territories ruled as political extensions of their mother countries.The later years of the 19th century saw the transition from "informal imperialism" (hegemony) by military influence and economic dominance, to direct rule (a revival of colonial imperialism) in the African continent and Middle East.
