What this topic is asking

Framework Key Idea 10.4 covers nineteenth-century imperialism, the period (roughly 1850 to 1914) when industrialized nations seized vast empires in Africa and Asia. It asks you to explain the causes (economic, strategic, and ideological) and the methods of imperial rule, including the Scramble for Africa. This topic is central to the enduring issues of power, inequality, and the impact of ideas, and it sets up the next topic on resistance and the causes of World War I.

What imperialism was

The causes of imperialism

The exam expects you to group the causes:

Crucially, industrial technology made conquest possible: steamships and railways moved troops and goods, the telegraph carried orders, machine guns gave overwhelming firepower, and medicines such as quinine let Europeans survive tropical diseases.

The Scramble for Africa

Between about 1880 and 1914, the European powers seized almost the entire continent of Africa in what is called the Scramble for Africa. To avoid war among themselves, they met at the Berlin Conference (1884 to 1885) and set rules for claiming African land, drawing borders on a map without a single African representative present. By 1914 nearly all of Africa was under European control (only Ethiopia and Liberia stayed independent). The arbitrary borders ignored existing peoples and kingdoms, creating problems that persist today.

Imperialism in Asia

In Asia, imperial control took several forms.

  • India. Britain ruled India directly after 1858 (the British Raj), calling it the "jewel in the crown" for its markets, raw materials (cotton, tea), and manpower.
  • China. China was not fully colonized but was forced into unequal treaties after the Opium Wars and divided into spheres of influence where different powers held economic privileges; the United States pushed the Open Door Policy to keep trade access.
  • Southeast Asia. France took Indochina, the Dutch held Indonesia, and Britain held Burma and Malaya.

The effects of imperial rule

Imperial powers extracted wealth (raw materials, cash crops, labor), built railways and ports to serve export economies rather than local needs, imposed foreign languages, religions, and administration, and drew arbitrary borders. Colonized peoples lost political control and were often treated as inferior. These effects, and the resistance they provoked, are the subject of the next topic.

Q1. Name the 1884 to 1885 meeting at which European powers set rules for dividing Africa. [Recall]

  • Cue. The Berlin Conference.

Q2. Explain one economic cause of nineteenth-century imperialism. [Short explanation]

  • Cue. Industrialized nations needed raw materials (such as rubber and cotton) to supply their factories and new markets to sell finished goods, so they seized colonies to control those resources and markets.

Regents GHG II (stimulus, 2024)1 marksAt the Berlin Conference (1884 to 1885), European powers met to set rules for claiming African territory, with no African representatives present. This best shows that (1) Africans controlled the division of their continent; (2) European powers divided Africa to serve their own interests; (3) imperialism had ended; (4) Africa was left independent.
Show worked answer →

A stimulus-based multiple-choice item assessing causation and power (Practices B and D).

The correct answer is (2). At the Berlin Conference the European powers divided Africa among themselves to avoid war and to serve their own economic and strategic interests, drawing borders without African input.

Why the others are wrong: (1) and (4) are contradicted by the exclusion of Africans and the partition itself; (3) imperialism was intensifying, not ending.

Markers reward identifying that Europeans, not Africans, controlled the partition for their own benefit.

Regents GHG II (CRQ cause-effect, 2023)2 marksDocument 1 describes an industrialized nation seeking guaranteed sources of rubber and cotton and new markets for its factory goods. Based on this document and your knowledge of social studies, identify one cause of nineteenth-century imperialism and explain how it drove expansion into Africa and Asia.
Show worked answer →

A 2-point Cause-and-Effect CRQ (Practices B and E).

Identify (1 point): one economic cause was the need for raw materials (such as rubber, cotton, and minerals) to feed industry and for new markets to sell finished factory goods. (Other acceptable causes: strategic bases and the Suez Canal, national prestige and competition, and ideologies such as the "civilizing mission" or Social Darwinism.)

Explain (1 point): industrialized nations needed steady supplies of raw materials their factories could not get at home and wanted captive markets for their surplus goods, so they conquered colonies in Africa and Asia to control those resources and markets.

Markers reward an economic (or other) cause plus a clear link to colonial expansion.
