Is Lynn Nottage's Ruined an effective vehicle for social change?

Lynn Nottage's play can certainly be viewed as a vehicle for social change. Ruined won the 2009 Pulitzer Prize for Drama. Nottage having won the award would not be considered an obvious choice, rather, a unique one: the prize is supposed to be given to "a distinguished play by an American author, preferably original in its source and dealing with American life." While Nottage is an American author, Ruined conveys the story of Mama Nadi, a brothel-keeper in the Democratic Republic of Congo. The play does not rely on Western characters or stereotypes, offering a ruthlessly real look into circumstances of sexual abuse and murder among women in the Second Congo War.
The decade-long civil war in the Congo saw more casualties than Iraq, Afghanistan and Darfur combined; by 2008, the war had caused approximately 5.4 million deaths. Ruined is a work of social justice politics, and the violence and ethical issues associated with the conflict are humanitarian concerns Nottage wished to share with the world. Nottage's variety of written works focus on marginalized and vulnerable populations, giving voice to their concerns.
In Ruined, Nottage focuses specifically on war against women and their bodies, which can be seen as part of a greater dialogue on wartime violence against women occurring throughout the modern world. The author views theatre and art as means of demonstrating society and culture in a way that moves people to find parallels between their own circumstances and those experienced by humanity as a whole. The play originally premiered at the Goodman Theatre and ran between November and December of 2008. It opened Off-Broadway at the New York City Center in 2009, after nine extensions. The play has since been performed in London, United Kingdom; Toronto, Canada; and Ipswich, Australia. The play's numerous accolades and productions around the world indicate its ability to move audiences and influence social change.
