However, despite the grief and loss that the women experience, they express a subtle element of rebellion and rejection of their inhumane treatment. As the women are gruesomely tortured by the Greeks, they have little room to object to their abuse, but Euripides emphasises how they do everything in their power to rebel against it. As a result, the play shows how those who are opressed by inhumane treatment are not necessarily forced into passivism, and that rebellion and activism always has some benefit to the individuals. + +The characters in *Women of Troy* are + +> Euripides' *Women of Troy* is not only an innovative perspective on the aftermath of the Trojan War, but also a portrayal of the barbaric actions of the Greeks towards the women and children the subjugated in the defeat of Troy.
