The Global History and Impact of Imperialism

Defining Imperialism and Its Scope

Imperialism is a state policy, practice, or advocacy of extending power and dominion, especially by direct territorial acquisition or by gaining political and economic control of other areas. Because it always involves the use of power—whether military, economic, or some subtler form—imperialism has often been considered morally reprehensible. Consequently, the term is frequently employed in international propaganda to denounce and discredit an opponent’s foreign policy.

The Primary Causes of Imperialism

Imperialism grew because industrial countries needed new markets, raw materials, and places to invest their capital. Colonies also provided international prestige and control of strategic areas. Population growth and the rise of machinery caused unemployment in Europe, leading many people to emigrate to the colonies. Scientific progress encouraged expeditions to discover new territories, plants, animals, and minerals. Finally, Europeans believed they were superior and thought it was their duty to spread their culture and Christianity to societies they considered “less civilized.”

The Three Phases of Colonization

  1. Military Conquest: The European power occupied the territory using its military superiority.
  2. Political and Administrative Control: A small group of Europeans governed the colony and maintained order.
  3. Colonial Economy: The metropole exploited resources and the local population to obtain raw materials and sell manufactured goods.

The Consequences of Imperial Rule

Political and Economic Consequences

Politically, imperialism was a major factor leading to the First World War. Economically, the colonizers took land from indigenous people to create single-crop plantations, where indigenous groups had to work in very poor conditions. Their traditional resources and ways of life were lost. Local crafts disappeared because they could not compete with the cheap, factory-made products from the colonizing countries. The colonizers also built ports and railways mainly to export raw materials, not to help the local population. As the colonizing countries controlled resources and trade, the colonies became economically dependent, creating the unequal world economy that still exists today.

Demographic, Social, and Cultural Consequences

European population pressure decreased because many people emigrated to the colonies. In the colonies, the population grew quickly because better hygiene and vaccines reduced deaths. Since the birth rate stayed high while mortality dropped, the population increased very fast. However, resources were not enough to support so many people, which caused hunger and poverty. Socially and culturally, colonizing countries forced their Western culture on indigenous people, making their own culture seem less important. Over time, social and racial separation appeared because colonizers thought they were better than the indigenous people. This separation continued for many years in many colonies.

Major Conflicts of the Imperial Era

  • The Opium Wars (1839-42, 1856-60): China vs. Britain and France. China tried to stop the opium trade, but Britain and France won.
  • The Crimean War (1853-1856): Russia vs. Britain, France, and the Ottoman Empire over control of the Black Sea; Russia lost.
  • The Anglo-Zulu War (1879): Britain vs. the Zulu Kingdom due to British expansion; Britain won.
  • The Berlin Conference (1884-1885): European powers gathered to divide Africa, mainly benefiting Belgium in the Congo.
  • The Fashoda Incident (1898): Britain vs. France over Sudan, ending with a British diplomatic victory.
  • The British Ultimatum to Portugal (1890): Forced Portugal to leave territories near Mozambique, giving Britain the advantage.
  • The Spanish-American War (1898): Spain vs. the United States over Cuba; the US won and took Cuba, Puerto Rico, the Philippines, and Guam.
  • The Boer War (1899-1902): Britain vs. Boer settlers for gold- and diamond-rich lands in South Africa; Britain won.
  • The Boxer Rebellion (1900-1901): China vs. several foreign powers due to anti-foreign sentiment; the foreign powers won.
  • The Russo-Japanese War (1904-1905): Russia vs. Japan over Manchuria and Korea; Japan won.
