Eóghan’s Stone at Tullaghoge

Abstract
In 1432, Domhnall Bog Ó Néill was killed in Ó Catháin territory, enabling his rival Eóghan, son of Niall Óg, to be inaugurated king of Tír Eóghain at Tullaghoge with clerical and learned support. Eóghan’s alliance with Sligo provoked conflict with Niall Garbh Ó Domhnaill of Tír Conaill, bringing armed diplomacy, Erne crossings, prolonged campaigning, burned settlements and crops. Raids exposed Armagh’s vulnerability, while bishops and learned families remained centres of hospitality, law and memory. Elsewhere, Ormond attacked Éile and Mac Murchadha challenged English power in Leinster. The year revealed fragmented authority, shifting alliances, and legitimacy unable to secure peace.
