The nuncio considered himself the virtual head of the Confederate Catholic party in Ireland. In 1646 the Supreme Council of the Confederates had come to an agreement with Ormonde, signed on 28 March 1646. Under its terms Catholics would be allowed to serve in public office and to found schools; there were also verbal promises of future concessions on religious toleration. There was an amnesty for acts committed in the Rebellion of 1641 and a guarantee against further seizure of Irish Catholic rebels' land by acts of attainder.
