The slogan “One People, One State, One Leader” corresponded to the policy of which of the following twentieth century political leaders?

Introduction / Context:
This general knowledge question focuses on political slogans and the leaders who used them. In twentieth century history, authoritarian and totalitarian regimes often promoted short, powerful slogans that summed up their ideology. Recognising which leader used “One People, One State, One Leader” helps test your familiarity with European history and political movements of that time.

Given Data / Assumptions:

• The slogan in question is “One People, One State, One Leader”.
• The options are Stalin, Hitler, Lenin and Mussolin (representing Mussolini).
• We assume the exam references common historical associations of slogans with their leaders.

Concept / Approach:
The slogan “One People, One State, One Leader” is the English translation of the German phrase associated with Adolf Hitler and the Nazi regime. It emphasised a single national community, a single national state and a single supreme leader. While other leaders like Stalin and Mussolini also ruled dictatorial regimes, this particular wording is linked specifically with Hitler. Therefore, we must correctly match the slogan with his name among the options.

Step-by-Step Solution:
Recall that Hitler was the leader of Nazi Germany and promoted ideas of extreme nationalism, racial unity and unquestioned obedience to a single leader. Identify that the phrase “One People, One State, One Leader” fits this ideology, emphasising unity around one leader and one state. Consider Stalin, who led the Soviet Union and followed a different ideological line, using other slogans specific to communism and socialism. Consider Lenin, the leader of the Bolshevik Revolution, whose key slogans included “Peace, Land and Bread” and ideas about workers and peasants, not this particular phrase. Consider Mussolini of Italy, who had fascist slogans of his own, but the exact phrase given in the question is most famously associated with Nazi Germany under Hitler.

Verification / Alternative check:
Typical history textbooks and competitive exam guides state that “Ein Volk, ein Reich, ein Führer” translated as “One People, One State, One Leader” was a well known Nazi slogan. It appeared on banners, posters and propaganda material. Hitler, as Führer, was the central figure of this slogan. Stalin and Lenin, though important in Soviet history, did not use this German slogan. Mussolini led Italian fascism and used Italian rallying cries, not this exact phrase.

Why Other Options Are Wrong:
Option A, Stalin, is wrong because he was associated with Soviet communism, with different slogans emphasising socialism, five year plans and the role of the proletariat. Option C, Lenin, is wrong because his slogans centred on revolution and social change, not on a single nationalist German leader. Option D, Mussolin, refers to Mussolini, whose regime had its own Italian slogans and symbols. None of these leaders used “One People, One State, One Leader” as their central phrase.

Common Pitfalls:
A common error is to mix up different dictators and assume that any strong slogan must belong to one of them randomly. Another pitfall is not remembering that the German word Führer specifically refers to Hitler and is tied to the slogan. To avoid confusion, link specific slogans with the language and country: German slogans with Hitler, Russian revolutionary slogans with Lenin and Stalin, and Italian ones with Mussolini.

Final Answer:
The slogan “One People, One State, One Leader” was the policy of Adolf Hitler, so option B is the correct answer.
