 Devlin was devoted to Dillon, who had helped him greatly in his rise to eminence, and Dillon in his turn had come to heavily rely on him, not only for control of the United Irish League and the Catholic organisation, the Ancient Order of Hibernians (AOH), but also because he was the outstanding representative of Ulster Nationalism.O'Brien had always been gravely disturbed by the Irish Parliamentary Party's involvement with "that sinister sectarian secret society", the Ancient Order of Hibernians, often known as the Molly Maguires, or "the Mollies" – what he called "the most damnable fact in the history of this country", and was bitterly resentful and unsparing in his attacks upon it.AOH members represented Catholic-nationalism of a Ribbon tradition, their Ulster Protestant counterpart the Orange Order.
