When did slavery end in africa?

Slavery end in Africa:

England followed this with the Slavery Abolition Act 1833 which liberated all slaves in the British Empire. English weight on different nations brought about them consenting to end the slave exchange from Africa.

On 1 August 1834, all slaves in the British Empire were liberated, yet they were contracted to their previous proprietors in an apprenticeship framework which was canceled in two phases; the primary arrangement of apprenticeships reached a conclusion on 1 August 1838, while the last apprenticeships were booked to stop on 1 August 1840.  

England canceled bondage all through its realm by the Slavery Abolition Act 1833 (with the eminent special case of India), the French settlements re-nullified it in 1848 and the U.S. abrogated subjection in 1865 with the thirteenth Amendment to the U.S. Constitution. In any case, when the war finished, in April 1865, just around fifteen percent of the slaves had really been liberated.
