Summary
Winston Churchill was prime minister of the United Kingdom during most of World War II and again in the early 1950s, making him one of the central British and Allied political leaders of the mid-20th century.
Historical role
He is significant because he helped sustain British resistance during the period of Axis ascendancy, shaped grand strategy within the Allied coalition, and remained a major voice in defining the meaning of both wartime struggle and the postwar geopolitical order.
Connections
