Key Terms to Review (21)

Adolf Hitler: Adolf Hitler was the leader of the National Socialist German Workers' Party (Nazi Party) and Chancellor of Germany from 1933 to 1945. He is infamous for instigating World War II through his aggressive expansionist policies and for orchestrating the Holocaust, resulting in the deaths of millions. His actions directly influenced the dynamics of the Nazi-Soviet Non-Aggression Pact, as he sought to secure Germany's eastern borders while preparing for a larger conflict in Europe.
Appeasement: Appeasement refers to a diplomatic strategy aimed at avoiding conflict by making concessions to an aggressive power. This approach is particularly significant in the context of the late 1930s, as European leaders sought to maintain peace with Adolf Hitler's Germany by allowing him to expand territorial claims without facing immediate consequences. The strategy was rooted in the desire to prevent another devastating war like World War I, but ultimately it enabled further aggression and contributed to the outbreak of World War II.
Axis Powers: The Axis Powers were a coalition of countries led by Germany, Italy, and Japan during World War II, opposing the Allied Powers. This alliance sought to expand their territories and influence through military aggression, ultimately leading to widespread conflict across Europe, Asia, and the Pacific. The collaboration among these nations was characterized by military cooperation and shared ideological goals, particularly fascism and militarism.
Baltic States: The Baltic States refer to the three countries of Estonia, Latvia, and Lithuania located on the eastern shore of the Baltic Sea. These nations were significant players in the geopolitical landscape of Eastern Europe, particularly during the time surrounding the Nazi-Soviet Non-Aggression Pact and the outbreak of World War II, as their fate was intricately linked to the interests of both Nazi Germany and the Soviet Union.
Blitzkrieg: Blitzkrieg, meaning 'lightning war' in German, refers to a military strategy that emphasizes rapid and surprise attacks to achieve swift victories. This tactic involves coordinated strikes using a combination of air and ground forces, aimed at disrupting the enemy's defenses and supply lines. The effectiveness of blitzkrieg was crucial in early World War II, particularly in relation to the rapid conquests of Poland and France, and later played a significant role in the German invasion of the Soviet Union.
Buffer zone: A buffer zone refers to a neutral area that serves as a barrier between two or more hostile entities or regions, aimed at reducing the likelihood of conflict and providing a sense of security.

Communism: Communism is a political and economic ideology advocating for a classless society in which all property is publicly owned and each person works and is paid according to their abilities and needs. This concept was central to the Soviet Union's identity, shaping its policies and international relations from the early 20th century onwards, influencing both domestic and foreign affairs during critical historical moments, including economic reforms, wartime alliances, and the Cold War.
Division of Eastern Europe: The division of Eastern Europe refers to the geopolitical and ideological split of the region during the late 1940s and early 1950s, primarily following World War II. This split occurred as a result of the power dynamics established by the Nazi-Soviet Non-Aggression Pact and the subsequent war, leading to the Soviet Union exerting control over much of Eastern Europe, while Western powers sought to limit Soviet influence. This division laid the groundwork for the Cold War and created a stark divide between communist and capitalist states.
Eastern European Nations: Eastern European nations refer to the countries located in the eastern part of Europe, which include nations like Poland, Hungary, the Czech Republic, Romania, and the former Soviet republics.
