After the end of World War II, no single foreign policy issue mattered more to the United States for the next 50 years as much as the Cold War. President Truman set the direction for the next eight presidents with the announcement of the containment policy. Crises in Berlin, China, and Korea forced Truman to back his words with actions. The Cold War kept defense industries humming and ultimately proved the limits of American power in Vietnam. Democracy was tested with outbreaks of Communist witch hunts.

In 1945, one major war ended and another began. The Cold War lasted about 45 years. There were no direct military campaigns between the two main antagonists, the United States and the Soviet Union. Yet billions of dollars and millions of lives were lost in the fight.

Berlin, Germany's wartime capital was the prickliest of all issues that separated the United States and Soviet Union during the late 1940s. The city was divided into four zones of occupation like the rest of Germany. However, the entire city lay within the Soviet zone of occupation. Once the nation of East Germany was established, the Allied sections of the capital known as West Berlin became an island of democracy and capitalism behind the Iron Curtain.

As the British and French Empires slowly yielded to independence movements, a new Third World emerged. This became the major battleground of the Cold War as the United States and the Soviet Union struggled to bring new nations into their respective orbits. Across the Third World, the two superpowers squared off through proxy armies.

President Kennedy faced a confident Soviet Union and a sleeping giant in the People's Republic of China. Fears of communist expansion plagued American foreign policy in places as distant as Vietnam and as close as Cuba. Like his predecessors, Kennedy made containment his chief foreign policy goal.

Before he became President, Reagan set the tone for relations with the Soviet Union by labeling the USSR an "evil empire." Around the world, communism seemed to be spreading. Soviet troops were in Afghanistan. Nicaragua was led by a Soviet-backed Sandinista government. Communist guerillas threatened to take over in neighboring El Salvador. Cuban-backed troops waged a successful insurgency in Angola. The age of détente was over.

The unraveling of the Soviet Bloc began in Poland in June 1989. Despite previous Soviet military interventions in Hungary, Czechoslovakia, and Poland itself, Polish voters elected a noncommunist opposition government to their legislature. The world watched with anxious eyes, expecting Soviet tanks to roll into Poland preventing the new government from taking power.

Allegories are similar to metaphors: in both the author uses one subject to represent another, seemingly unrelated, subject. However, unlike metaphors, which are generally short and contained within a few lines, an allegory extends its representation over the course of an entire story, novel, or poem. This lesson plan will introduce students to the concept of allegory by using George Orwell’s widely read novella, Animal Farm, which is available on Project Gutenberg.

This collection uses primary sources to explore the Atomic Bomb and the Nuclear Age it started. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

The documents for this activity are drawn from those that might be typically found on an advanced placement history test, supplemented by materials featured in Teachrock lessons. As such, this activity may be used as a means to prepare students for an advanced placement test, or as an assessment tool at the end of a Cold War unit. A variety of approaches are provided that allow teachers to use the documents to engage their students in the classroom.

This lesson highlights the changing relationship between the city center and the suburb in the postwar decades, especially in the 1950s. Students will look at the legislation leading up to and including the Federal Highway Act of 1956. They will also examine documents about the history of Levittown, the most famous and most important of the postwar suburban planned developments.

This lecture course provides students with a comprehensive introduction to the international relations of the People's Republic of China. China's foreign relations during the Cold War as well as contemporary diplomatic, security and economic issues will be examined to identify and explain China's foreign policy goals and their implementation since 1949. Throughout, this course will investigate the sources of conflict and cooperation in China's behavior, assessing competing explanations for key events and policies. Readings will be drawn from political science, history, and international relations theory.

This lesson plan attempts to dissolve the artificial boundary between domestic and international affairs in the postwar period to show students how we choose to discuss history.

Most historians agree that the world has never come closer to nuclear war than it did during a thirteen-day period in October 1962, after the revelation that the Soviet Union had stationed several medium-range ballistic missiles in Cuba. This lesson will examine how this crisis developed, how the Kennedy administration chose to respond, and how the situation was ultimately resolved.

This course covers the role of physics and physicists during the 20th century, focusing on Einstein, Oppenheimer, and Feynman. Beyond just covering the scientific developments, institutional, cultural, and political contexts will also be examined.

This course examines systematically, and comparatively, great and middle power military interventions, and candidate military interventions, into civil wars from the 1990s to the present. These civil wars did not easily fit into the traditional category of vital interest. These interventions may therefore tell us something about broad trends in international politics including the nature of unipolarity, the erosion of sovereignty, the security implications of globalization, and the nature of modern western military power.

The aim of this course is to introduce and analyze the international relations of East Asia. With four great powers, three nuclear weapons states, and two of the world's largest economies, East Asia is one of the most dynamic and consequential regions in world politics. This course will examine the sources of conflict and cooperation in both periods, assessing competing explanations for key events in East Asia's international relations. Readings will be drawn from international relations theory, political science and history.
