 Supported by Andrew, George and Elias Ellicott and heavily promoted by the Society for the Promotion of the Abolition of Slavery of Maryland and of Pennsylvania, the early editions of the almanacs achieved commercial success.After these editions were published, William Wilberforce, William Pitt, Charles James Fox and other prominent abolitionists praised Banneker and his works in the British House of Commons.Printers then distributed at least nine editions of Banneker's 1795 almanac.
