In the summer of 1845, a man named Frederick Douglass disembarked ship in Dublin. It marked the start of a two-year lecture tour of Britain and Ireland by the celebrated author, orator - and escaped slave. Advised to leave America for his own safety after the publication of his eloquent and incendiary abolitionist memoir, Douglass proceeded to spend four months in Ireland describing and denouncing the horrors of slavery: packing full halls with his oratorical skill; sharing a stage with 'The Liberator' Daniel O'Connell; and taking the pledge from 'The Apostle of Temperance' Fr. Theobald Mathew.
