What was a major reason for the development of the policy of appeasement?

A major reason for the development of the policy of appeasement was the desire to maintain peace in Europe following the devastation of World War I. Many countries, particularly Britain and France, believed that by conceding to some of the demands of aggressive powers like Nazi Germany, they could prevent another large-scale conflict. This approach was influenced by a widespread belief that the Treaty of Versailles had been too harsh on Germany, and that satisfying Hitler’s ambitions might stabilize the region. Ultimately, this strategy proved ineffective, as it encouraged further aggression instead of deterring it.
