Final answer:
Democratic nations pursued a policy of appeasement in the 1930s due to a fear of aggression, a desire to avoid another world war, and the sentiment of the civilian population.
Step-by-step explanation:
The policy of appeasement pursued by Western democratic nations in the 1930s was driven by several factors. Firstly, appeasement was based on a fear of aggression. After the devastating experience of World War I, many European nations were reluctant to engage in another war and sought to avoid conflict at any cost. Secondly, appeasement aimed to avoid another world war. The leaders of democratic nations believed that by appeasing Adolf Hitler and making compromises, they could maintain peace and prevent the outbreak of a devastating conflict. Thirdly, the desire to avoid war was driven by the sentiment of the civilian population, who were vehemently opposed to war after the trauma of the previous world war. The governments of France and Britain, in particular, had unstable and unpopular positions, and concessions to Hitler were seen as an effort to preserve peace and stability.
