Introduction: Why the Cold War Matters in APUSH
The Cold War (1945–1991) is one of the most important units in AP U.S. History. It shaped U.S. foreign policy, domestic politics, and global power struggles for nearly half a century. For APUSH students, the Cold War frequently appears in both multiple-choice questions (MCQs) and Free Response Questions (FRQs).
This guide will break down the must-know Cold War events in a clear timeline, highlight major themes, and explain how to connect them to APUSH exam questions. RevisionDojo’s curated resources will help you master this era without memorization overload.
Step 1: The Origins of the Cold War
