The Northern Ireland Civil Rights Association (NICRA) organized a march in Derry to highlight the systemic discrimination against the Catholic minority and to demand equal rights in housing, voting, and employment. Building on the momentum from civil rights movements globally, the protest aimed to peacefully call attention to grievances that had been largely ignored by the British government. As the march commenced, thousands participated, carrying placards and chanting slogans advocating for civil liberties.

However, the atmosphere quickly turned hostile as police, claiming the procession was unauthorized, moved in to disperse the demonstrators. The marchers were met with force, as police charged the crowd, wielding batons and employing riot gear. The situation escalated into chaos, with many bystanders caught in the violence. The event shocked both local communities and observers nationwide, drawing attention to the growing discontent in Northern Ireland and the need for reform.

Media coverage of the violent scene further ignited public opinion and fears about the rising tensions in Northern Ireland. It became a pivotal moment in civil rights activism in the region, leading to increasing participation in protests and rallies, eventually contributing to escalated political strife. The incident underscored deep divides and the urgent need for dialogue and reform within Northern Irish society.
