Is Lizzy Bennet a forerunner of feminism?

In my opinion Elizabeth Bennet is a forerunner of the feminism because she defences the free wishes of the women, a good example of that is when she rejects the offer of Mr Collins but after that she show that she accept the bases of her society when she want that her sister, Lidia, became married with Mr Wickham only to safe the name of his family. I think that the writer, Jane Austen, showed in the book a lot of new social and philosophic trends that appear have a real trend a few years later, probably Locke and other writers were inspired by this novel.
