Trade and Empire Europeans colonized parts of Asia, Africa and the Americas in the late 15th-16th centuries to gain control over the production and trade of valuable commodities like sugar, cotton, tobacco, and to reduce risks and create monopolies for profit. Colonies provided cheap resources and markets for manufactured goods, and were a source of national prestige in the "race for empire" among European powers. By the 18th century, the major colonial powers were Britain, France, Spain, Portugal, the Netherlands, and later Germany and Russia, competing violently at times over territories and trade.
