What are 3 reasons for Arthur miller writing his play?

1. To criticize McCarthyism: Miller lived during the McCarthy era, when the United States government prosecuted and persecuted alleged Communists without much regard for due process. He wrote "The Crucible" as an allegory of the hearings led by Senator Joseph McCarthy, in which innocent people were interrogated, pressured and falsely accused with little evidence.

2. To explore mass hysteria: Miller's play portrays a community gripped by mass hysteria and fear, where people turn against one another based on baseless accusations and rumors. He aimed to warn against the dangers of unchecked fear and panic, which can lead to injustice persecution.

3. To highlight the importance of individual conscience: In "The Crusibe" many characters face choices that test their consciences. Some, like Abigail Williams, chooses to give into self-interest and manipulation, while others, like John Proctor, stand up for their beliefs even at great person risk. Miller's play emphasizes the importance of moral courage and the consequences of making ethical decisions.
