The Guardian [SEP] Slavery and the American Civil War
On 31 December 1862, cotton workers held a meeting at the Free Trade Hall in Manchester which resolved "its detestation of negro slavery in America, and of the attempt of the rebellious Southern slave-holders to organise on the great American continent a nation having slavery as its basis". There was a comment that "an effort had been made in a leading article of the "Manchester Guardian" to deter the working men from assembling together for such a purpose". The newspaper reported all this and published their letter to President Lincoln while complaining that "the chief occupation, if not the chief object of the meeting, seems to have been to abuse the "Manchester Guardian"".
