About International Day for the Remembrance of the Slave Trade and Its Abolition
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 International Day for the Remembrance of the Slave Trade and Its Abolition 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.
