Act Up-Paris became one of the most notable protest groups in France in the mid-1990s. Founded in 1989, and following the New York model, it became a confrontational voice representing the interests of those affected by HIV through openly political activism. Action=Vie, the English-language translation of Christophe Broqua's study of the grassroots activist branch, explains the reasons for the group's success and sheds light on Act Up's defining features--such as its unique articulation between AIDS and gay activism. Featuring numerous accounts by witnesses and participants, Broqua traces the history of Act Up-Paris and shows how thousands of gay men and women confronted the AIDS epidemic by mobilizing with public actions. Act Up-Paris helped shape the social definition not only of HIV-positive persons but also of sexual minorities. Broqua analyzes the changes brought about by the group, from the emergence of new treatments for HIV infection to normalizing homosexuality and a controversy involving HIV-positive writers' remarks about unprotected sex. This rousing history ends in the mid-2000s before marriage equality and antiretroviral treatments caused Act Up-Paris to decline.
