In Great Britain, the efforts of Christian humanitarians such as William Wilberforce and Thomas Clarkson, as well as an economy that pivoted from a mercantile system to industrial capitalism, eventually led to the cessation of the British slave trade in 1807. The Abolition Act of 1833 brought the total elimination of the institution throughout the Empire. Eager to show their support for President Abraham Lincoln and the Emancipation Proclamation, which would become effective on 1 January 1863, a group of English laborers crafted the entreaty. Their efforts were not without need. Lincoln, who had long favored a system of gradual emancipation to be carried out voluntarily by the states, came slowly to the idea of emancipation by executive order. — by Laura M. Miller, Vanderbilt University.

The Civil War (1861-1865) disrupted US cotton production causing distress in cotton manufacturing in Europe. Nevertheless, the cotton workers in Manchester, England supported the Union in its fight against slavery, writing a letter to Lincoln in solidarity. The City of Manchester, England, supported Lincoln in his fight against slavery, despite the hardships that his blockade of America’s southern ports were having on the country's cotton industry.

As citizens of Manchester, assembled at the Free-Trade Hall, we beg to express our fraternal sentiments toward you and your country. We rejoice in your greatness as an outgrowth of England, whose blood and language you share, whose orderly and legal freedom you have applied to new circumstances, over a region immeasurably greater than our own. We honor your Free States, as a singularly happy abode for the working millions where industry is honored. One thing alone has, in the past, lessened our sympathy with your country and our confidence in it—we mean the ascendency of politicians who not merely maintained negro slavery, but desired to extend and root it more firmly.

Since we have discerned, however, that the victory of the free North, in the war which has so sorely distressed us as well as afflicted you, will strike off the fetters of the slave, you have attracted our warm and earnest sympathy. We joyfully honor you, as the President, and the Congress with you, for many decisive steps toward practically exemplifying your belief in the words of your great founders: "All men are created free and equal." You have procured the liberation of the slaves in the district around Washington and thereby made the centre of your Federation visibly free. You have enforced the laws against the slave-trade and kept up your fleet against it, even while every ship was wanted for service in your terrible war. You have nobly decided to receive ambassadors from the negro republics of Hayti and Liberia, thus forever renouncing that unworthy prejudice which refuses the rights of humanity to men and women on account of their color. In order more effectually to stop the slave-trade, you have made with our Queen a treaty, which your Senate has ratified, for the right of mutual search. Your Congress has decreed freedom as the law forever in the vast unoccupied or half unsettled Territories which are directly subject to its legislative power. It has offered pecuniary aid to all States which will enact emancipation locally and has forbidden your Generals to restore fugitive slaves who seek their protection. You have entreated the slave-masters to accept these moderate offers; and after long and patient waiting, you, as Commander-in-Chief of the Army, have appointed tomorrow, the first of January, 1863, as the day of unconditional freedom for the slaves of the rebel States. Heartily do we congratulate you and your country on this humane and righteous course. We assume that you cannot now stop short of a complete uprooting of slavery. It would not become us to dictate any details, but there are broad principles of humanity which must guide you. If complete emancipation in some States be deferred, though only to a predetermined day, still in the interval, human beings should not be counted chattels. Women must have the rights of chastity and maternity, men the rights of husbands, masters the liberty of manumission. Justice demands for the black, no less than for the white, the protection of law—that his voice be heard in your courts. Nor must any such abomination be tolerated as slave-breeding States, and a slave market—if you are to earn the high reward of all your sacrifices, in the approval of the universal brotherhood and of the Divine Father.
