Quick Summary

Vansittartism was a doctrine developed by British diplomat Sir Robert Vansittart. It posited that German aggression, from the Franco-Prussian War onward, was consistently supported by the German populace. Consequently, Vansittart advocated for Germany's permanent demilitarization and political isolation to prevent future wars.12

Vansittart, who served in various diplomatic roles, including as permanent undersecretary at the Foreign Office, warned the British government about Germany's rising military power and urged rearmament. His views, which became known as Vansittartism, were controversial and led to his marginalization by Prime Minister Neville Chamberlain, who sought a settlement with Adolf Hitler. Despite this, Vansittart continued to express his views, particularly in radio broadcasts during World War II, arguing that Nazi aggression was rooted in German history.1
