In August 1875, at the O’Connell centenary celebrations in Boston, three famous American abolitionists recalled the importance of O’Connell’s role in the American anti-slavery movement. John Greenleaf Whittier saw no reason to change the high opinion of O’Connell’s anti-slavery services that he had formed many years earlier; William Lloyd Garrison commented on the aid and inspiration he had always received from O’Connell; and Wendell Phillips noted how the Irishman’s actions as an agitator had influenced the abolitionists’ own concept of moral reform. Parallel celebrations in Dublin also mentioned this aspect of O’Connell’s career, but perhaps it is fitting that his anti-slavery commitment should receive greatest stress in Boston, which was not only an important Irish-American centre, but also the city with the closest links with British anti-slavery.

Newspaper files for the period 1830–60 indicate that a number of American Minstrel Shows visited Ireland at a time when the Irish Anti-Slavery movement was particularly vigorous. The shows occasioned considerable comment in the press, but, surprisingly, little or none among the abolitionists, who were usually avid readers of anything in the press pertaining even remotely to the U.S.A. and the Negro. Yet the popular Irish image of the Negro must have been in part determined by such performances, and for this reason they deserve some attention. Irish audiences were also, in this period, treated to dramatizations of episodes in Negro life and to the exhibition, as curiosities, of African tribesmen; but by far the most common was the American Minstrel Show.
