Aodh Mór Ó Néill (anglicised as Hugh ONeill), (c. 1540 - July 20, 1616), was an Irish chieftain of the late 16th century, who became 2nd Earl of Tyrone (known as the Great Earl). ONeills career was played out against the background of the Tudor re-conquest of Ireland, and he is best known for leading the resistance during the Nine Years War (Ireland), the strongest threat to English authority in Ireland since the Anglo-Norman conquest in 1172.
