International Day for the Remembrance of the Slave Trade and Its Abolition
UNESCO 29 C/Resolution 40
UNESCO 29 C/Resolution 40
This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
The International Day for the Remembrance of the Slave Trade and its Abolition is observed on 23 August to remember the transatlantic slave trade, resistance to slavery and the historical processes that contributed to abolition.
UNESCO frames the day as a remembrance and education observance that examines the causes, systems, consequences and cross-cultural legacies of slavery and the slave trade.
Why it matters
The observance is anchored in the history of resistance by enslaved people rather than treating abolition as something granted only by institutions or governments. It therefore supports historical study of agency, resistance, exploitation and the long-term consequences of slavery.
This 23 August UNESCO observance should not be merged with the UN’s 25 March remembrance day for victims of slavery and the transatlantic slave trade or the 2 December abolition-of-slavery day; each has a different institutional history and emphasis.
History
UNESCO proclaimed the International Day for the Remembrance of the Slave Trade and its Abolition in 1997 through 29 C/Resolution 40.
The date recalls the night of 22 to 23 August 1791 in Saint-Domingue, now Haiti, when an uprising began that became a pivotal event in the struggle against the slave system. UNESCO records early commemorations in Haiti in 1998 and on Gorée Island, Senegal, in 1999.

Study primary and scholarly sources about the Haitian Revolution, Atlantic slavery and resistance by enslaved people.
Work with museums, archives, educators and descendant communities to contextualize local links to slavery and the slave trade.
Avoid imagery or language that reduces enslaved people to passive victims; include resistance, family, culture and agency.
Distinguish historical chattel slavery from contemporary forms of exploitation carefully rather than treating different systems as identical.
