In the decade of the 1650's many of the Irish confederate leaders, lay and ecclesiastical, found themselves exiles in Europe. In exile, they naturally turned again to the disputes which had disrupted the confederation and had helped to make Cromwell's campaign easier than it might otherwise have been. These disputes grew more and more bitter in the disappointment of defeat; and no matter what point they started from, they had a way of returning to the censures which the papal nuncio, Rinuccini, had pronounced on 27 May 1648. These censures had divided the confederation beyond hope of reunion; even after ten years, they were still regarded by one party as having been justly inflicted, necessary for the preservation of the Catholic religion, while the other considered them to have been unjust and invalid, and the real cause of the subsequent overthrow of the confederation.
