<span>The 20th century play which addressed the issues behind the AIDS epidemic and its impact on the gay community is known as <u>Angels in America: A Gay Fantasia on National Themes.</u>
It was written in 1993 by the American playwright Tony Kushner, and won numerous awards for its depiction of the gay community. The whole play is symbolic and metaphoric, given that angels and other supernatural beings also appear so as to communicate with the “closeted” and scared people of the gay community. Throughout the play, we see numerous gay characters who have contracted AIDS, and we follow them around through their daily lives and see how they cope with this disease, but also how other people react to them having it.</span>
