The High Kingship of Ireland was a significant political and cultural institution in ancient Ireland, representing the supreme authority over the island. The title of High King was not hereditary; instead, it was often contested among various regional kings, known as Lords, who ruled over different provinces. The most recognized seat of the High King was at Tara, a site of great historical and spiritual importance. The role of the High King included maintaining peace among the provinces and leading military campaigns. The concept of High Kingship was deeply rooted in Irish mythology and legend, with figures like Brian Boru being notable High Kings. The system gradually declined with the arrival of the Normans in the 12th century, leading to a more fragmented political landscape.
