The Clapham Sect was a group of influential evangelical Christians in the early 19th century, primarily based in Clapham, London. They were known for their commitment to social reform and played a significant role in various humanitarian causes, including the abolition of the slave trade in the British Empire. Key figures included William Wilberforce, Thomas Clarkson, and Granville Sharp. This group was characterized by its strong moral convictions and active engagement in politics and social issues. They sought to promote Christian values in society and were involved in founding several organizations aimed at improving education, public health, and the welfare of the poor. Their legacy continues to influence social justice movements today.
