An Inspector Calls was first 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. The consequences of the Birlings' actions highlight Priestley’s ideas on social responsibility do we look after one another in society. The difference between the younger and older characters reactions to Eva Smith's death shows how Priestley viewed different generations . He viewed the younger generation as hope for the future and this is why both Sheila and Eric learn a lesson from the Inspector. How the male characters behave towards the females in the play highlights important points on gender and inequality. Class issues are also dealt with by having a middle class family involved in the death of a working class girl. J B Priestley explored these themes in a lot of his work. They are political in nature and are still relevant today. Age is an important theme in An Inspector Calls. Priestley uses it to show how he believed that there was hope in the younger generation's ability to learn and change. The older characters' opinions and behaviours are stubbornly fixed. Mr Birling refuses to learn and Mrs Birling cannot see the obvious about herself and her children. Eric and Sheila however are younger they accept their mistakes and offer the chance for a brighter future. An Inspector Calls was written after World War Two. As many British men went away to fight during the war, their positions in work had to be filled by women. This helped change existing perceptions. Men had to acknowledge the fact that women were just as capable as them. As a result of this many women enjoyed a newfound freedom that working and earning money allowed them. Not all men saw this change in attitude as a good thing and stayed stuck in the past. Priestley explores the impact of these new gender roles through the independence of Eva Smith and the sexist attitudes of Mr Birling. Before World War Two Britain was divided by class. Two such classes were the wealthy land and factory owners and the poor workers. The war helped bring these two classes closer together and rationing meant that people of all classes were eating and even dressing the same. The war effort also meant that people from all classes were mixing together. This was certainly not the case before. Priestley wanted to highlight that inequality between the classes still existed and that the upper classes looked down upon the working-class in post war Britain.
