performed in the UK just after the end of World War Two, in 1946. It was a time of great change in Britain and many writers were concerned with the welfare of the poor. At that time there was no assistance for people who could not afford to look after themselves. Priestley wanted to address this issue. He also felt that if people were more considerate of one another, it would improve quality of life for all. This is why social responsibility is a key theme of the play. Priestley wanted his audience to be responsible for their own behaviour and responsible for the welfare of others.
