Diktat refers to a harsh or non-negotiable order or decree imposed by one party on another, often without any room for discussion or dissent. In the context of peace settlements after World War I, particularly the Treaty of Versailles, diktat was used to describe the punitive terms imposed on Germany and its allies, which were seen as one-sided and dictated by the victorious powers. This term reflects the sentiments of those who felt that the treaties disregarded their sovereignty and agency in negotiations.
