In a formal letter to Pope John, Donnell Oneyl, the King of UTyrone, articulates the historical claims of the Irish people to their own sovereignty, tracing their lineage back to ancient kings and highlighting the injustices they have suffered at the hands of English rulers. He emphasizes the unbroken line of Irish kings who upheld the Catholic faith and defended their lands against foreign oppression. Oneyl expresses concern over the misrepresentation of their status and the ongoing injustices, particularly referencing Pope Adrian's controversial transfer of dominion to King Henry of England, which he views as a violation of their rights.
