William Wilberforce was a British politician in the late 1700s and early 1800s who was prominent in the struggle to abolish the slave trade and slavery in the British Empire. After converting to Christianity, he felt called to promote Christian ethics in public life. He introduced numerous bills to Parliament over two decades seeking to outlaw the slave trade, all of which failed to pass initially. However, he persisted in his efforts. The slave trade was abolished in 1807 and slavery was abolished in 1833, shortly before Wilberforce's death.
