• A. Abolition movements were driven by religious reformers who opposed Enlightenment ideals.

• C. Abolition occurred due to economic interests alone, with no Enlightenment influence.
• D. Britain's abolition of the slave trade happened independently of Enlightenment ideas.

Answer: (B)

Enlightenment ideas about natural rights and universal humanity provided the language and standards that abolitionists used to argue against slavery. The insistence that all people possess inherent liberty and are equal before reason made slavery seem not just unfair but logically incompatible with a just human order. This gave abolitionists a powerful framework beyond religious or economic critique, turning the defense of freedom into a universal principle.

Think of how reformers and writers tied liberty to universal rights, arguing that enslaved individuals deserved the same moral consideration as free citizens. They gathered and presented evidence, challenged the idea that some people could be justifiably owned, and pressed governments to align laws with these rational, rights-based principles. Figures such as Clarkson, Equiano, and Wilberforce helped translate these ideas into public advocacy, coalitions across religious groups, and parliamentary efforts.

Britain’s Slave Trade Act of 1807 shows how this Enlightenment-influenced rhetoric and moral urgency could translate into legal reform. The act didn’t emerge from economics alone or in isolation from ideas; it arose because the Enlightenment provided a universal criterion of justice that made the slave trade indefensible in the eyes of many lawmakers and citizens. In that sense, abolition movements were able to mobilize opinion and shape law by appealing to reason, human dignity, and the claim that political authority should protect universal rights rather than uphold a system that violated them.
