The war guilt question (German: Kriegsschuldfrage) is the public debate that took place in Germany for the most part during the Weimar Republic, to establish Germany's share of responsibility in the causes of the First World War. Structured in several phases, and largely determined by the impact of the Treaty of Versailles and the attitude of the victorious Allies, this debate also took place in other countries involved in the conflict, such as in the French Third Republic and the United Kingdom.
