What this topic is asking

Topic 9.1 is a contextualization topic. The College Board wants you to set the scene for Unit 9: explain the devastated, divided, superpower-dominated Europe that the Second World War left behind and how it set the stage for the Cold War and the contemporary era. You are building the background, not yet narrating the Cold War itself.

A devastated and diminished Europe

The rise of two superpowers

From alliance to rivalry

The wartime partnership did not survive victory.

Why it mattered

This context is the background to everything in Unit 9. The devastated, divided, superpower-dominated Europe of 1945 set in motion the whole of the unit: the Cold War itself (Topic 9.3), the rebuilding and integration of western Europe (Topics 9.2 and 9.10), the decolonization of the European empires (Topic 9.9), and eventually the fall of communism (Topic 9.7). Setting this context lets you explain why the second half of the 20th century took the shape it did.

Q1. What two superpowers dominated the world after 1945, and what divided them? [Recall]

  • Cue. The United States and the Soviet Union; they were divided by opposed ideologies (capitalist democracy versus communist dictatorship) and clashing visions for the postwar world.

Q2. Explain how the legacy of World War II set the stage for the Cold War. [Short explanation]

  • Cue. The war left Europe devastated and stripped of global dominance, elevated the US and USSR to superpower status with armies meeting in a defeated Germany, and, as the common enemy fell, turned their opposed ideologies and aims into the mutual rivalry that split Europe and began the Cold War.

A Long Essay Question (LEQ), scored on the 6-point causation rubric.

Thesis (1): "The legacy of World War II shaped the Cold War decisively, leaving a devastated, divided Europe dominated by two superpowers whose opposed ideologies and aims turned wartime allies into rivals."

Contextualization (1): the destruction of the war and the collapse of European power.

Evidence (2): the devastation and division of Europe; the rise of the US and USSR; the clash of capitalist and communist aims.

Analysis (2): argue the war's legacy created the conditions while ideology drove the rivalry, then add complexity by noting the role of mutual fear and misperception.
