Does Antigone's character represent pre-feminist ideas in 'Antigone'?

Yes, Antigone's character represents pre-feminist ideas in "Antigone" by Sophocles (495 B.C.E. - 405 B.C.E.).

Specifically, a woman, Theban Princess Antigone, is the protagonist as the main character, the holder of great powers and doer of great deeds. She manages to bury her brother, challenge an unjust law, defend the gods and Theban traditions and defy a heartless dictator. She succeeds even though she gives her life to her cause and even though she lives in a male dominated society where women are expected to follow the masculine lead.
