The most well-known of these is perhaps the Movimento Passe Livre (Movement for Free Fare), one of the principal catalysts of the political protests in June with its focus on the current model of public transportation. The others are the Fórum Popular de Saúde do Estado de São Paulo (Popular Forum for Health in the State of São Paulo), a group that unites various collectives in defense of public health; the Coletivo Autônomo dos Trabalhadores Sociais (Autonomous Collective of Social Workers), which unites, principally, social assistance advocates that operate in São Paulo; the Periferia Ativa (Active Periphery), funded by communities in the South Zone and metropolitan region of the capital São Paulo; and the Comitê Contra o Genocídio da População Preta, Pobre e Periférica (Committee Against the Genocide of the Black, Poor, and Underprivileged Population), which combats police violence and violence by vigilante groups.
