Madame de Staël's pamphlet, published anonymously by the London printers Ellerton & Henderson, calls on the sovereigns of continental Europe to fall into line with Britain's 1807 Act of Abolition, and abolish the slave trade. De Staël argues that the sacred cause of abolition could be a monument to the rulers of France, Portugal, Austria, Prussia, and Russia, signatories of the 1814 Treaty of Paris, and an apt tribute to the role of Britain in bringing peace to Europe.
