Quakers, originally from The Netherlands and Germany, were the first to formulate criticism of slavery in the Caribbean and North America in the Germant0own Declaration of 1688. Only in the late 18th century Quakers also had political influence in the UK, e.g. through the discourse of Wilberforce and Thomas Clarkson, describing the horrors of the Middle Passage. At the same time in France, some Enlightenment philosophers also critical of slavery, though often ambiguously. Most explicit was the discourse of Condorcet.
