World War II

World War II saw leaders exert their impact through a combination of strategic military decisions, charismatic influence over their nations, and the implementation of policies that shaped the war's course. For instance, leaders like Winston Churchill and Franklin D. Roosevelt rallied their countries with inspiring speeches and firm diplomatic alliances, bolstering morale and securing critical support. On the other hand, figures such as Adolf Hitler and Joseph Stalin used authoritarian control, propaganda, and aggressive military strategies, which significantly influenced the war's direction and its eventual outcomes.
