Turlough was born around 1530 at Seanchaisleán, close to the modern town of Newtownstewart. He was the fourth son of Niall Connallach O'Neill, Tanist of Tyrone. As Tanist, Niall Connallach was designated to succeed his uncle Conn Bacach as The O'Neill. Turlough's mother may have been Niall Connallach's wife, Rose O'Donnell, the daughter of Manus O'Donnell, The O'Donnell of the neighbouring kingdom of Tyrconnell. Turlough was the grandson of Art óg macConn, The O'Neill, and was a direct descendant of Brian macNéill Ruad, The O'Neill and ruler of Tír Eoghain.
Turlough as O'Neill
Making professions of loyalty to the Queen of England in the year following Shane's assassination, Turlough sought to strengthen his position by alliance with the O’Donnells, MacDonnells and MacQuillans. But his conduct giving rise to suspicions, an expedition under The 1st Earl of Essex was sent against him, which met with such doubtful success that in 1575 a treaty was arranged by which O’Neill received extensive grants of lands and permission to employ three hundredScottish mercenaries. A further treaty in 1578, negotiated by Lady Agnes, confirmed Turlough’s vast land holdings in Ulster, granted him a Knighthood and the British titles of Earl of Clanconnell and Baron of Clogher, for life, and allowed him to retain for life the personal army of Scottish mercenaries negotiated three years before. in submission. In the background Sidney seems to be embracing O'Neale as a noble friend. Still, at the outbreak of rebellion in Munster his attitude again became menacing, and for the next few years he continued to intrigue against the English authorities through clandestine alliances with Spain and Scotland, yet he maintained virtual control of Ulster until 1593, when he was forced by poor health and military setbacks to concede power to his principal rival, Hugh, brother of Brian, whom Turlough had assassinated in 1562 during Shane O’Neill's absence at the court of Queen of England. Hugh was recognised by Turlough Luineach as captain of Tyrone, and as his Tanist, in 1593. During summer 1595 Hugh seized the last castle still held by Turlough Luineach, razed it, and drove him into the wilderness. He died between 9 and 12 September 1595, and was buried at Ardstraw, probably at the Franciscan Friary founded by his ancestors. Turlough Luineach had successfully survived as "The O'Neill" from 1567 until 1595, a turbulent quarter century that saw the most concerted efforts by the English administration to weaken and marginalise his authority in Ulster. He is frequently depicted by contemporary English historians as a weak, drunken buffoon, but his continued survival as the O'Neill through this period speaks of his considerable skill as a ruler and of a sustained policy of successful compromise.
Turlough Luineach has the distinction of being one of the most highly praised rulers by the Gaelic poets and musicians of his time. His father Niall Connallach had been a celebrated patron of the arts and Turlough Luineach avidly followed his example. He sheltered Uilliam Nuinseann when the poet was accused of conspiracy in the Baltinglass rebellion of 1580.
