What policy was reinforced at the Munich conference?

At the Munich Conference in 1938, the policy of appeasement was reinforced, as leaders from Britain, France, Germany, and Italy agreed to allow Nazi Germany to annex the Sudetenland region of Czechoslovakia without military intervention. The aim was to prevent further conflict in Europe by conceding to some of Adolf Hitler's demands. This decision was met with significant criticism later, as it ultimately emboldened Nazi Germany and failed to secure lasting peace.
