Paul Cullen and His Contemporaries: With Their Letters from 1820-1902

Peadar MacSuibhne compiled this extensive five-volume historical series, which was published between 1961 and 1977. The work serves as a meticulous collection of primary source documents centered on Cardinal Paul Cullen, a pivotal 19th-century figure in the Irish Catholic Church who served as the Archbishop of Dublin. MacSuibhne aimed to preserve the archival record of a man who significantly influenced the religious, social, and political landscape of Ireland during a period of transition.

The volumes consist primarily of correspondence, offering a scholarly bridge to the nineteenth century by detailing the internal operations and external challenges faced by the Irish hierarchy. MacSuibhne’s work is widely regarded by historians as an indispensable academic resource for understanding Cullen's reactionary stance on Irish nationalism and his efforts to centralize Roman influence in Ireland. It remains a fixture in research libraries for those studying the complexities of Irish ecclesiastical history.
