P. W. Joyce,
The Story of Ancient Irish Civilization
“ CHAPTER I. HOW THE ANCIENT IRISH PEOPLE WERE GOVERNED BY THEIR KINGS AND CHIEFS.There were in Ireland, from times beyond the reach of history, kings, who were of various grades according to the extent of the country or district they ruled over. The highest of all was the king of Ireland, who lived in the royal palace at Tara. He was called the Ard-ri [ard-ree] , i.e., ‘High king’ or Over-king, because he claimed authority over all the others. There was also a king over each of the five provinces—Leinster, Munster, Connaught, Ulster, and Meath—who were subject to the Ard-ri. ”
