The
Clapham Sect or
Clapham Saints were a group of
Church of England social reformers based in
Clapham, London at the beginning of the 19th century (active c. 1790–1830). They are described by the historian Stephen Michael Tomkins as "a network of friends and families in England, with
William Wilberforce as its centre of gravity, who were powerfully bound together by their shared moral and spiritual values, by their religious mission and social activism, by their love for each other, and by marriage".
