ABSTRACT
This chapter provides a brief overview of Argentina's Lesbian and Gay (LG) movement. It examines the relationship between the movement and the state and analyses the impact the latter has had on the former in three areas: federalism, the judicialization of politics, and alliances between state and non-state actors. These dramatic events represented the beginning of important victories in the struggle waged by Argentina's Lesbian and Gay (LG) movement to challenge the traditional definition of marriage; a struggle that culminated with the reforms to the Civil Code approved by the Argentine Congress in 2010 that allowed for gay marriage nationally. From being a movement whose members had not long ago struggled simply to obtain legal recognition for the first gay and lesbian organization, the movement has managed to place Argentina at the forefront of gay rights in Latin America, and the world, by forcing the state to expand the very definition of citizenship in unprecedented ways.
