Partly, the white working-class sent petitions to the Parliament to abolish slavery. For example in 1788 (in Manchester) 10,000 people signed one petition. Then again in 1792 (in Manchester) 20,000 people signed another petition. This put pressure on the Parliament to end slavery.

The campaining still went on even after the slave trade was abolished since many slaves were still kept in captivity. By 1814, 1 500 000 people had signed these petitions.
