International Day for the Remembrance of the Slave Trade and of its Abolition

At its 29th session, the UNESCO Executive Board adopted the Resolution 29 C/40, proclaiming 23 August, the International Day for the Remembrance of the Slave Trade and of its Abolition, in tribute to the night of 22 to 23 August 1791, when the uprising of slaves took place in Santo Domingo island (today Haiti and the Dominican Republic) and, led later on the abolition of the transatlantic slave trade and the creation of the first Black independent State, the Republic of Haiti.
