What is the central theme?

I might consider that Female identity is a major theme. When speaking to the female characters in Trifles, Henderson and the other men make a key mistake in their assumption that the women derive their identity solely from their relationship to men, the dominant gender. For example, Henderson tells Mrs. Peters that because she is married to the sheriff, she is married to the law and therefore is a reliable follower of the law. Mrs. Peters' response is "Not--just that way," suggesting that over the course of the play, she has rediscovered a different aspect of her identity that ties more closely to her experience as a woman than to her marriage to Henry Peters. As Mrs. Hale concludes, women "all go through the same things--it's all just a different kind of the same thing." For Mrs. Hale, Minnie Wright's murder of her husband is the ultimate rejection of her husband's imposed identity in favor of the memory of the person Minnie Foster used to be.
