Britain banned the slave trade in 1807 and abolished slavery itself in 1833. Twenty-six years separate the two, and conflating them is the most common error made about British abolition.
View 1833 →Law & regulation
The 1807 Act made trading in enslaved people illegal and left slavery itself lawful in British colonies for another 26 years. Conflating the two dates is the most common error made about British abolition.
