Final answer:
Many Europeans favored appeasement to prevent another devastating war, to save on war expenses, and because some viewed Germany's actions as justifiable or a deterrent against communism. This policy aimed to satisfy German demands in the hopes of maintaining peace, but it ultimately failed.
Step-by-step explanation:
During the 1930s, many Europeans favored appeasement of Germany for several reasons. They saw it as a means to prevent loss of life in another war, after the horrific experiences of World War I, and to save the expense of another war. Appeasement also aligned with prevailing sentiments that opposed the war, with pacifism being a popular ideology among the war-scarred populations. Moreover, some in Britain felt the Treaty of Versailles had been too harsh on Germany and that Hitler's actions were partially justified, while both France and Britain regarded fascism as a bulwark against the spread of communism. The policy, therefore, was adopted to satisfy German demands under the belief that Hitler would be content and cease further aggression, which ultimately proved to be ill-conceived.
