Aodh Mór Ó Néill (c. 1550-1616), anglicised Hugh O’Neill, was a Gaelic politician and leader of the Irish confederation during the Nine Years War. He took power initially as Baron of Dungannon, then as Earl of Tyrone, but broke with English titles and became Ó Néill, chief of his clan. Most well known for his leading role in the Nine Years War and his enduring alliance with Aodh Ruadh Ó Domhnaill, after a string of military victories he was defeated at Kinsale. He left Ireland during the Flight of the Earls and spent his remaining days in Rome.
