Patrick J Flynn observing the landscape, the semi mythical and politics of early Ireland over some three millennia sets the scene for the establishment and development of the Hy-Tuirtre Kingdom. He assembles and follows the real story of that early kingdom from Conn of the Hundred Battles in AD 123 to the final collapse of the kingdom and the death of Thomas O'Flynn the last King of Hy-Tuirtre in 1365.
Julius Caesar's Roman Legions defeated the Celtic tribes of France and England a generation before the birth of Christ. The remaining pockets of Celtic civilization that survived in Ireland held steadfastly to their traditions until the Gaelic Order was closed by England's Lord Mountjoy in 1601. Mythology and historical records facilitate the tracking and development of that Celtic tradition and the Hy-Tuirtre Kingdom until the conquest of Ulster.
By following the rise of the Hy-Tuirtre Kingdom over the time line of their millennium facilitates the reader in gaining an understanding of the workings of Celtic and Gaelic tradition. The Hy-Tuirtre although not alone in the Oirghiallian Federation (Oriel) experienced many changes to their landscape and kingdom throughout the period of their existence in the Ulster heartland. Insurmountable force and change had lasting impact on their traditions when the Hy-Tuirtre found themselves at a point in time at the front line of the Anglo Norman expansion which hampered and prevented them from executing their traditional Celtic survival strategy.
