Unit 8: Cold War and Decolonization

c. 1900 – present  |  Exam Weight: 8–10%

🕊️ Unit Overview

After 1945, the world was reshaped by two parallel revolutions: the Cold War between the United States and the Soviet Union, and the decolonization of Africa, Asia, and the Caribbean. These processes intersected: superpowers competed for influence over newly independent states, and decolonization movements were often shaped by Cold War ideologies. Meanwhile, social movements worldwide — civil rights, feminism, anti-apartheid, student protest — challenged entrenched hierarchies. By the late 1980s, the Soviet system collapsed, ending the Cold War and opening a new era.

Big question: How did the Cold War rivalry, decolonization, and global resistance movements reshape the world between 1945 and 1991?

✍️ Short-Answer Practice (SAQ)

SAQ 1 — Cold War and Decolonization (No Stimulus)

  1. Identify ONE way the Cold War shaped decolonization in the period 1945–1991.
  2. Explain ONE method colonized peoples used to gain independence from a European power.
  3. Explain ONE challenge faced by newly independent states after 1945.
Click to see a sample response

(a) The Cold War shaped decolonization by turning independence struggles into proxy wars: in Angola, for example, the Soviet Union and Cuba backed the MPLA while the U.S. and South Africa backed UNITA, making postcolonial politics a site of superpower rivalry rather than purely local concerns.

(b) In India, Mohandas Gandhi led a campaign of nonviolent civil disobedience — satyagraha — including the 1930 Salt March and mass boycotts of British goods, which along with the Indian National Congress's political mobilization forced Britain to negotiate independence in 1947.

(c) Many newly independent African states inherited borders drawn at the Berlin Conference that cut across ethnic and linguistic lines; this contributed to civil wars and separatist movements, such as the Biafran War in Nigeria (1967–70), as new states struggled to build unity.

SAQ 2 — Stimulus (Kennedy on the Berlin Wall, 1963)

"Freedom has many difficulties and democracy is not perfect, but we have never had to put a wall up to keep our people in, to prevent them from leaving us... All free men, wherever they may live, are citizens of Berlin, and, therefore, as a free man, I take pride in the words 'Ich bin ein Berliner.'"
— President John F. Kennedy, speech in West Berlin, 1963

  1. Identify ONE purpose of Kennedy's use of the image of the Berlin Wall in this speech.
  2. Explain ONE specific historical context from the early 1960s that helps explain Kennedy's speech.
  3. Explain ONE long-term consequence for Europe of the division symbolized by the Berlin Wall.
Click to see a sample response

(a) Kennedy uses the Berlin Wall as concrete evidence that communist regimes had to physically imprison their own citizens, framing the Cold War as a moral contest between freedom and tyranny in order to rally Western Europeans behind U.S. leadership.

(b) The Wall had been built only two years earlier, in August 1961, amid sharp U.S.–Soviet tension that had just culminated in the Cuban Missile Crisis (October 1962); Kennedy's visit sought to reassure West Germans that the United States remained committed to defending them despite those tensions.

(c) The Berlin Wall symbolized the division of Germany and Europe into NATO and Warsaw Pact blocs for nearly three decades; when it fell in November 1989, its collapse triggered the rapid unraveling of communist regimes in Eastern Europe and the end of the Cold War in 1991.
