The document provides historical context for the play An Inspector Calls, setting it in 1912 Britain prior to World War I. Society was highly unequal, with a tiny minority owning most wealth. Conditions for the poor were appalling. The play reveals truths about Britain's social and political class structures and the arrogance of the upper/middle classes and desperation of the lower classes. It warns that society needs to change to become more equal and caring, otherwise consequences could follow.
