The Anniversary of the Killing of Pidjiguiti is observed in Guinea-Bissau every August 3. This public holiday commemorates the victims of the Pidjiguiti massacre that occurred in 1959 when police opened fire on dock workers striking for better wages at Pijiguiti Docks, resulting in over 50 deaths. The event marked a turning point for the African Party for the Independence of Guinea and Cape Verde, founded by Amílcar Cabral, leading to a shift from nonviolent resistance to armed struggle for independence from Portuguese colonial rule. In recognition of its significance, Guinea-Bissau declared August 3 a memorial day following its independence in 1974. The day serves as a reminder of the sacrifices made during the fight for liberation.
