The first gay pride parade in Mexico occurred in Mexico City in 1979, and it was attended by over a thousand people. Ever since, it has been held annually under different slogans, with the purpose of bringing visibility to sexual minorities, raising awareness about HIV/AIDS, fighting homophobia, and advocating for LGBT rights, including the legalization of civil unions, same-sex marriages, and LGBT adoption. In 2009, more than 350,000 people attended the gay pride march in Mexico City—100,000 more than the previous year. Guadalajara has also held their own Guadalajara Gay Pride every June since 1996, and it is the second largest gay pride parade in the country. Gay pride parades have also spread to the cities of León, Guanajuato, Puebla, Tijuana, Toluca, Cancun, Acapulco, Mérida, Xalapa, Cuernavaca, Chihuahua, Matamoros, Saltillo, Mazatlan, Los Cabos, Puerto Vallarta, and Hermosillo, among others.
