Abolitionists used powerful speeches and presentations to engage people and persuade them to join the abolitionists’ cause.
They used real testimonials from people who had seen the suffering of slaves, they tried to approach people by making them aware of the situation that was being lived at that time.
A lot of people joined the cause, they stopped consuming sugar that slaves grew and started buying sugar made by the freemen. The inhabitants of Bristol also turned against slavery, despite being a port city.
All these attitudes were promoted by the speeches and presentations of abolitionists.
