Key Terms to Review (18)

Berlin Blockade: The Berlin Blockade was a significant event during the early years of the Cold War, occurring from June 1948 to May 1949, when the Soviet Union blocked all ground routes to West Berlin in an attempt to exert control over the entire city. This blockade was a direct response to the introduction of a new currency in West Germany and the merging of the western zones, which the Soviets viewed as a threat to their influence. The United States and its allies responded with the Berlin Airlift, delivering supplies to West Berliners and showcasing the escalating tensions between East and West.
Brinkmanship: Brinkmanship is a foreign policy strategy that involves pushing dangerous events to the brink of active conflict, in hopes of achieving favorable outcomes through the threat of severe consequences. This approach relies on the willingness to escalate tensions to avoid actual warfare, showcasing determination and resolve. In the context of the early years of the Cold War, brinkmanship was a critical tactic used by both superpowers as they sought to assert their dominance and protect their interests without engaging in direct military confrontation.
Capitalism: Capitalism is an economic system where private individuals or businesses own and control the means of production and trade, aiming to generate profit. This system emphasizes free markets, competition, and minimal government intervention, allowing supply and demand to dictate prices and production levels. Capitalism has shaped various aspects of society, influencing economic policies, social structures, and labor relations throughout history.
Comecon: Comecon, officially known as the Council for Mutual Economic Assistance, was an economic organization established in 1949 to promote economic cooperation among socialist countries, primarily in Eastern Europe. This organization was formed as a response to the Marshall Plan and aimed to facilitate trade, coordination of economic policies, and mutual development among its member states during the early years of the Cold War.
Cominform: Cominform, short for Communist Information Bureau, was established in 1947 as a means for the Soviet Union to coordinate and direct communist parties around the world. It served as a response to the growing influence of Western ideologies and was crucial in solidifying Soviet control over Eastern Europe during the early years of the Cold War. By promoting a unified communist front, Cominform sought to ensure that member parties adhered to Moscow's directives, thereby increasing the USSR's geopolitical power during this tense period.
Communism: Communism is a political and economic ideology advocating for a classless society where all property is publicly owned and each person works and is paid according to their abilities and needs. This concept emerged in the 19th century, largely articulated by Karl Marx and Friedrich Engels, and gained prominence in the early 20th century as a revolutionary movement. In the context of the early Cold War years, communism became a major ideological rival to capitalism, significantly shaping international relations and domestic policies across the globe.
Eastern Bloc: The Eastern Bloc refers to the group of socialist states in Central and Eastern Europe that were aligned with the Soviet Union during the Cold War. This bloc included countries like Poland, East Germany, Czechoslovakia, Hungary, Romania, and Bulgaria, and it was characterized by a centralized economy and one-party political systems. The Eastern Bloc played a crucial role in the dynamics of the Cold War, serving as a counterbalance to the Western capitalist nations and being a key player in the ideological conflict between communism and democracy.

This war emerged from the division of Korea at the end of World War II and became a significant event in the early years of the Cold War, symbolizing the ideological struggle between communism and democracy.
Marshall Plan: The Marshall Plan, officially known as the European Recovery Program, was a U.S. initiative launched in 1948 to aid the economic recovery of Western European countries after World War II. This program aimed to rebuild war-torn regions, remove trade barriers, modernize industry, and improve European prosperity to prevent the spread of communism during the early years of the Cold War.
Mutually assured destruction: Mutually assured destruction is a military strategy and doctrine where two or more opposing sides possess enough nuclear weapons to destroy each other completely, ensuring that any nuclear attack by one would result in the total annihilation of both. This concept emerged during the Cold War, leading to a tense standoff between superpowers, as the fear of total destruction deterred direct conflict and maintained a fragile peace.
NATO: NATO, or the North Atlantic Treaty Organization, is a military alliance established in 1949 to provide collective defense against aggression, primarily from the Soviet Union during the Cold War. The organization was formed by 12 founding member countries in response to the growing tensions between the Western powers and the Eastern Bloc.
