The March of the Family with God for Liberty was a monumental gathering that took place in São Paulo, Brazil, amid a tense political climate marked by growing concerns over communism and the governance of President João Goulart. On this day, it is estimated that over 500,000 people from diverse backgrounds converged, signifying a unifying protest against perceived threats to the country's democratic foundations and a call for more conservative governance. Participants included families, clergy, military personnel, and members of various political affiliations, all advocating for a return to order and traditional values.

The individuals attending the march were notably influenced by the Church and media, which emphasized anti-communism and the need for social stability. The march served as a rallying point for those who believed Goulart's policies leaned too far left and who feared the potential spread of communism in Brazil. The demonstrators carried banners and chanted slogans denouncing Goulart, calling for military intervention to restore what they viewed as societal equilibrium and safety.

The March of the Family with God for Liberty was instrumental in galvanizing public sentiment against Goulart and ultimately played a key role in the political upheaval that led to the military coup later that month. The deeply conservative and religious undertones of the march highlighted the intersection of faith and politics in Brazil, setting the stage for years of military dictatorship that would follow.
