The explosion of gay visibility following the street riots at the Stonewall Inn in 1969 brought, for the first time, tens of thousands of lesbians and gay men out of the closets and into headline news around the world. Never before had so many gay people at one moment stepped into the spotlight of mainstream American politics, culture, and entertainment. More than any city, New York became overnight the center of the new "Gay Power" movement and served as the focal point for gay protest and politics for the next decade. Gay Power, chronicles the tumultuous first wave of the modern gay rights movement.

From the first-ever gay student group launched at Columbia University in 1965 to the Gay Liberation Front, the Gay Activist Alliance, and other vanguard organizations that emerged from the Stonewall riots, David Eisenbach draws on archival material and numerous firsthand accounts from the individuals who built the movement. Unlike their predecessors, this new generation of lesbians and gay men spoke as a community, established political clout, appeared openly on television and in the press, demanded equal rights with heterosexuals, and pioneered protest tactics like the "zap," which later ACT UP employed famously in the 1980s.
