Kings of Osraige
The kings of Osraige or kings of Ossory reigned over Ossory (Osraige in Irish), which was largely a buffer state between Leinster and Munster, in Ireland. Its southern border were the Suir and Barrow rivers, though it originally extended to the sea and its rulers had some influence over the Norse kings of Waterford. In the north it may have once stretched over the Slieve Bloom and reached the River Shannon, but in the historic era it generally stayed to the south of these mountains, the boundary generally being the river Barrow.
Its main town and dynastic capital was Kilkenny.
The name Osraige is said to be from the Usdaie, a tribe that Ptolemy's map of Ireland places in roughly the same area that Ossory would later occupy. Other tribes in the vicinity were the Brigantes and the Cauci. The Osraighe themselves claimed to be descended from the Érainn people.
