What was the reason Giles Corey got arrested?

Giles Corey was arrested for refusing to give the name of an informant. Throughout "The Crucible," Corey is depicted as a steadfast and principled character who values integrity and truth. When he is pressured to reveal the name of a person who supposedly made accusations against others, he chooses to protect that individual’s identity rather than comply with the court’s demands. This refusal showcases his commitment to his beliefs and the principles of justice, even in the face of his own arrest.

The context of the play emphasizes the theme of integrity versus the corrupt nature of the witch trials, and Corey's stance is a powerful example of this struggle. His character illustrates the personal consequences that come from standing up against an unjust system, making his arrest a significant moment in the narrative.
