On November 7, 2017, Bob Snelling spoke to the Rotary Club of Sandy Springs about William Wilberforce, the Parliamentarian responsible for removing slavery from the British Empire.
From Wikipedia: William Wilberforce (24 August 1759 – 29 July 1833) was an English politician, philanthropist, and a leader of the movement to stop the slave trade. A native of Kingston upon Hull, Yorkshire, he began his political career in 1780, eventually becoming an independent Member of Parliament (MP) for Yorkshire (1784–1812). In 1785, he became an Evangelical Christian, which resulted in major changes to his lifestyle and a lifelong concern for reform.
Wilberforce was convinced of the importance of religion, morality and education. He championed causes and campaigns such as the Society for the Suppression of Vice, British missionary work in India, the creation of a free colony in Sierra Leone, the foundation of the Church Mission Society, and the Society for the Prevention of Cruelty to Animals. His underlying conservatism led him to support politically and socially controversial legislation, and resulted in criticism that he was ignoring injustices at home while campaigning for the enslaved abroad.
