In what ways and for what reasons did rulers of single party states play an important role in world affairs between 1917 and 1945?

 From the 2000 IBDP Paper 2 Exam


Between 1917 and 1945, the world witnessed the rise and fall of several single-party states, with their rulers playing pivotal roles in shaping world affairs. This period, marked by two World Wars and the interwar years, saw leaders such as Stalin, Hitler, and Mussolini exerting significant influence on global politics, economics, and society. Their actions and policies not only impacted their respective nations but also had far-reaching consequences on the international stage. The reasons for their influence were manifold, ranging from their strategic geopolitical positions, their aggressive foreign policies, to their ideological influence. 

Stalin's leadership of the Soviet Union from the mid-1920s until his death in 1953 was a defining factor in world affairs during this period. His policies and actions had a profound impact on both the Soviet Union and the world at large. Conquest argues that Stalin's industrialisation policies, particularly the Five-Year Plans, transformed the Soviet Union from a predominantly agrarian society to a major industrial power. This rapid industrialisation not only changed the socio-economic fabric of the Soviet Union but also significantly altered the global balance of power. The Soviet Union emerged as a formidable adversary to the capitalist West, setting the stage for the Cold War. The Five-Year Plans, despite their immense human cost, were instrumental in equipping the Soviet Union with the industrial capacity necessary to withstand the German onslaught during World War II. As Davies notes, the industrial output of the Soviet Union increased fourfold between 1928 and 1940, providing the essential infrastructure for the production of military hardware. This industrial might was crucial in turning the tide of war in favour of the Allies. Stalin's role in the formation of the Comintern, or Communist International, was another significant aspect of his influence on world affairs. The Comintern aimed to spread communism worldwide, leading to the creation of numerous communist parties globally. As McMeekin points out, the Comintern played a crucial role in the internationalisation of the Russian Revolution, influencing political developments in several countries and contributing to the global ideological divide.

Another single-party state ruler who played a significant role in world affairs during this period was Adolf Hitler, the leader of Nazi Germany from 1934 to 1945. Hitler's aggressive foreign policies and expansionist ideology led to the outbreak of World War II, the most devastating conflict in human history. Kershaw argues that Hitler's disregard for the Treaty of Versailles, which had ended World War I and imposed punitive conditions on Germany, was a key factor in escalating tensions in Europe. His remilitarisation of the Rhineland, annexation of Austria (Anschluss), and subsequent dismemberment of Czechoslovakia were blatant violations of the treaty and destabilised the European balance of power. Hitler's racial ideology, encapsulated in his concept of Lebensraum or 'living space', was another significant factor in shaping world affairs. This ideology justified the expansion of Germany at the expense of other nations, particularly in Eastern Europe, which Hitler considered to be the natural habitat of the Aryan race. As Aly notes, this racial ideology not only led to the invasion of Poland and the Soviet Union but also resulted in the genocide of six million Jews in the Holocaust, an event that has had profound implications for global consciousness and international law. Hitler's economic policies, particularly the implementation of a war economy, also had significant global implications. Tooze points out that the German economy under Hitler was geared towards war production, with a significant increase in military spending. This economic mobilisation played a crucial role in Germany's initial successes in World War II and influenced other nations to adopt similar measures.

Hitler's diplomatic manoeuvres also had a significant impact on world affairs. His signing of the Molotov-Ribbentrop Pact with the Soviet Union in 1939, as mentioned earlier, allowed Germany to wage a single-front war, leading to the rapid conquest of Poland and France. However, his decision to break the pact and invade the Soviet Union in 1941 proved to be a strategic blunder that ultimately led to Germany's defeat. As Evans argues, the invasion of the Soviet Union not only opened up a second front for Germany but also turned a potential ally into a formidable enemy. Hitler's role in the initiation and conduct of World War II had far-reaching consequences. The war resulted in the death of an estimated 70 to 85 million people, approximately 3 to 4% of the world's population. It led to significant changes in the global balance of power, with the emergence of the United States and the Soviet Union as superpowers. The war also led to the creation of the United Nations and the establishment of a new international order based on collective security. Furthermore, Hitler's policies and actions led to significant changes in international law. The Nuremberg Trials, held after the end of World War II, resulted in the conviction of several top Nazi officials for crimes against humanity, a concept that was codified in international law as a result of the Holocaust. As Marrus points out, the trials established the principle of individual accountability for war crimes and crimes against humanity, a significant development in international law. The influence of Hitler, therefore, extended far beyond Germany. His policies and actions reshaped the world, leading to a global conflict, significant shifts in the balance of power, and profound changes in international law and global consciousness.

Mussolini, the leader of Fascist Italy from 1922 to 1943, was another single-party state ruler who had a significant impact on world affairs during this period. His aggressive foreign policies, expansionist ambitions, and the ideological influence of Fascism played a crucial role in shaping the international landscape. Mussolini's invasion of Ethiopia in 1935 is a key example of his impact on world affairs. The invasion was a blatant violation of the League of Nations' principles, and the League's failure to take effective action against Italy discredited the organization and exposed the weaknesses of the collective security system. As Bosworth argues, this emboldened other aggressive powers, particularly Nazi Germany, and contributed to the escalation of tensions leading up to World War II. Mussolini's alignment with Hitler in the Rome-Berlin Axis and the subsequent Pact of Steel further escalated tensions in Europe. These alliances committed Italy to Germany's side in the event of a war, thereby increasing the potential scale of the conflict. As Knox notes, Mussolini's decision to join the war on Germany's side in 1940, although largely opportunistic, had significant implications for the Mediterranean theatre of the war and diverted valuable Allied resources.

Mussolini's domestic policies, particularly his efforts to transform Italy into a totalitarian state, also had a significant impact on world affairs. His Fascist regime, characterised by a one-party system, state control of the economy, and a cult of personality, served as a model for other authoritarian regimes. As Gentile points out, Fascism's emphasis on nationalism, militarism, and social unity had a profound influence on Hitler and the Nazi Party, contributing to the ideological underpinnings of World War II. Mussolini's role in the Spanish Civil War further underscores his influence on world affairs. His support for Franco's Nationalist forces, including the provision of troops and military equipment, was instrumental in the Nationalists' victory. As Payne notes, this intervention not only altered the course of the Spanish Civil War but also deepened the ideological divide in Europe, contributing to the polarisation of the continent into Fascist and anti-Fascist camps. The fall of Mussolini in 1943 and Italy's subsequent surrender to the Allies marked a turning point in World War II. As Morgan argues, Italy's capitulation weakened the Axis Powers and opened up a new front in Europe, hastening the end of the war. In conclusion, Mussolini's policies and actions, both domestically and internationally, had a profound impact on world affairs. His aggressive foreign policies, his role in the spread of Fascism, and his contribution to the outbreak and conduct of World War II make him a significant figure in the history of the period between 1917 and 1945.

The period between 1917 and 1945 was marked by the rise of single-party states, with their rulers playing significant roles in world affairs. Stalin, Hitler, and Mussolini, leaders of the Soviet Union, Nazi Germany, and Fascist Italy respectively, exerted substantial influence on global politics, economics, and society. Their actions and policies, driven by ideological convictions and geopolitical ambitions, had far-reaching consequences that extended beyond their national borders. Stalin's industrialisation policies and his leadership during World War II transformed the Soviet Union into a global superpower. Hitler's aggressive foreign policies and racial ideology led to the outbreak of World War II and the Holocaust, events that reshaped the world in profound ways. Mussolini's aggressive foreign policies, his establishment of a Fascist regime, and his support for Franco in the Spanish Civil War contributed to the escalation of tensions leading up to World War II and influenced the ideological landscape of Europe. These leaders, through their actions and policies, significantly shaped the course of world affairs during this period. Their influence was not confined to their respective nations but extended to the global stage, affecting the balance of power, the conduct of war, and the ideological divide that characterised this era. Their legacies continue to influence our understanding of this critical period in world history.
