International relations 1918-1975 Study Guide

The period between 1918 and 1939, often referred to as the Interwar Period, was a complex era defined by both attempts at international cooperation and the resurgence of aggressive nationalism, ultimately leading to another global conflict. Following the devastation of World War I, nations sought to establish new mechanisms for peace. The Treaty of Versailles, signed in 1919, aimed to settle the war's aftermath but also sowed seeds of resentment, particularly in Germany. The League of Nations, an international organisation proposed by US President Woodrow Wilson, was established with the goal of preventing future wars through collective security and disarmament. However, its effectiveness was severely hampered by the absence of major powers like the USA and a lack of enforcement mechanisms.

Alongside these efforts to build peace, numerous factors contributed to increased tension and conflict. Economic instability, particularly the Great Depression from 1929 onwards, fueled extremist ideologies and undermined democratic governments. Fascist regimes in Italy (Mussolini) and Nazi Germany (Hitler) rose to power, advocating aggressive expansionist policies and rejecting international cooperation. Imperial Japan also pursued expansion in Asia. The failure of the League of Nations to decisively act against acts of aggression, such as the Japanese invasion of Manchuria (1931-1932) and the Italian invasion of Abyssinia (1935-1936), demonstrated its weakness. Britain and France, weakened by the war and economic crises, often pursued policies of appeasement, hoping to avoid another major conflict by conceding to the demands of aggressive states. This allowed Germany to rearm, remilitarise the Rhineland, and annex Austria and parts of Czechoslovakia, further escalating tensions and making war almost inevitable by 1939.

Appeasement refers to the policy of making concessions to aggressive powers in order to avoid conflict. In the context of British foreign policy towards Nazi Germany in the 1930s, it largely involved sacrificing smaller national interests to preserve European peace. Initially, appeasement was viewed differently by contemporaries compared to later historians. During the 1930s, many in Britain, including Prime Minister Neville Chamberlain, saw appeasement as a necessary and pragmatic approach to prevent another devastating war like World War I. They believed that by addressing some of Hitler's grievances, such as the Treaty of Versailles' harsh terms, they could avoid a larger confrontation. This view was supported by public opinion, which was largely pacifist and war-weary.

However, this perception began to shift dramatically after the outbreak of World War II in September 1939. Critics, most notably Winston Churchill, argued that appeasement had been a catastrophic failure, demonstrating weakness and only emboldening Hitler to pursue greater territorial ambitions. This post-war consensus portrayed appeasers as naive, cowardly, and morally bankrupt, directly contributing to the war. This 'Guilty Men' narrative, popularized by a 1940 pamphlet, dominated historical interpretation for decades.

From the 1960s onwards, a revisionist interpretation emerged. Historians like A.J.P. Taylor suggested that appeasement was not necessarily a policy of cowardice but a rational response given Britain's economic and military weaknesses, as well as the perceived injustices of the Treaty of Versailles. They argued that Britain was not ready for war and needed time to rearm. Some revisionists even claimed that Chamberlain was strategically buying time. More recently, post-revisionist historians have acknowledged the complexities, suggesting that while appeasement may have been understandable given the circumstances, it ultimately failed to prevent war and had serious moral implications. They often emphasize the moral failings and misjudgments of the appeasers while recognizing the constraints they faced rather than simply condemning them as 'guilty men'. The ongoing debate highlights how historical events are reinterpreted through new evidence, changing perspectives, and the lessons of subsequent generations.
