This page serves as an index of lists of kings of the Gaelic kingdoms of Ireland of the Early Medieval period.
Lists of monarchs in the British Isles are lists of monarchs that have reigned over the various kingdoms and other states that have existed in the British Isles throughout recorded history. They include monarchs of Britain as a whole, and monarchs of states that covered part or whole of what are now England, Ireland, Scotland, Wales and the Isle of Man.
Connacht or Connaught, is one of the four provinces of Ireland, in the west of Ireland. Until the ninth century it consisted of several independent major Gaelic kingdoms.
This article concerns the Gaelic nobility of Ireland from ancient to modern times. It only partly overlaps with Chiefs of the Name because it excludes Scotland and other discussion. It is one of three groups of Irish nobility, the others being those nobles descended from the Hiberno-Normans and those granted titles of nobility in the Peerage of Ireland.
Toirdhealbhach Mór Ua Conchobhair anglicised Turlough Mór O'Conor, was King of Connacht (1106–1156) and High King of Ireland.
The Soghain were a people of ancient Ireland. The 17th-century scholar Dubhaltach Mac Fhirbhisigh identified them as part of a larger group called the Cruithin. Mac Fhirbhisigh stated that the Cruithin included "the Dál Araidhi [Dál nAraidi], the seven Lóigisi [Loígis] of Leinster, the seven Soghain of Ireland, and every Conaille that is in Ireland."
The Kingdom of Breifne or Bréifne, anglicized as Breffny, was a medieval overkingdom in Gaelic Ireland. It comprised what is now County Leitrim, County Cavan and parts of neighbouring counties, and corresponds roughly to the Roman Catholic Diocese of Kilmore. It had emerged by the 10th century, as a confederation of túatha headed by an overking drawn from the Uí Briúin Bréifne.
The Uí Briúin were a royal dynasty of Connacht. Their eponymous apical ancestor was Brión, son of Eochaid Mugmedon and Mongfind, and an elder half brother of Niall of the Nine Hostages. They formed part of the Connachta, along with the Uí Fiachrach and Uí Ailello, putative descendants of Eochaid Mugmedon's sons Fiachra and Ailill. The Uí Ailello were later replaced as the third of the Three Connachta, through genealogical sleight of hand, by the Uí Maine.
Donnchad Donn mac Flainn was High King of Ireland and King of Mide. He belonged to Clann Cholmáin, a branch of the southern Uí Néill.
The Bishop of Kilmore is an episcopal title which takes its name after the parish of Kilmore, County Cavan in Ireland. In the Roman Catholic Church it remains a separate title, but in the Church of Ireland it has been united with other bishoprics.
The Diocese of Kilmore is a Latin Church diocese which is mainly in the Republic of Ireland although a few parishes are in Northern Ireland. It is one of eight suffragan dioceses which are subject to the Metropolitan Archdiocese of Armagh.
The royal sites of Ireland were the seats of the Gaelic kings of Ireland. Medieval sources describe them as the ceremonial capitals of various Irish kingdoms, where kingly inaugurations, assemblies and athletic games were held. Archaeological investigations show that many royal sites were culturally significant for thousands of years before recorded history, and they often include ancient monuments such as Neolithic burial mounds, standing stones, cairns and enclosures.
Gormfhlaith is an Irish language feminine given name meaning "blue princess" or "illustrious princess".
Áed in Macáem Tóinlesc or Aodh an Macaoimh Tóinleasg was a 12th-century ruler of Tulach Óc and Tír Eogain. He was the first of his family to play a significant role in the high politics of northern Ireland, following the death of the Muirchertach Mac Lochlainn king of Tír Eogain and high king of Ireland.
Cairbre Drom Cliabh was an Irish túath in the ancient confederation of Íochtar Connacht, now County Sligo in the west of Ireland. It is now represented by the barony of Carbury. Also known as Cairbre na Catha. It existed from at least the 6th century to the 16th century AD.
The O'Brien dynasty was an Irish Clan and noble house of Munster, founded in the 10th century by Brian Boru of the Dál gCais (Dalcassians). After becoming King of Munster, through conquest he established himself as Ard Rí na hÉireann. Brian's descendants thus carried the name Ó Briain, continuing to rule the Kingdom of Munster until the 12th century where their territory had shrunk to the Kingdom of Thomond which they would hold for just under five centuries.
The Northern Uí Néill was any of several dynasties in north-western medieval Ireland that claimed descent from a common ancestor, Niall of the Nine Hostages. Other dynasties in central and eastern Ireland who also claimed descent from Niall are termed the Southern Uí Néill. The dynasties of the Northern Uí Néill were the Cenél Conaill and Cenél nEógain, named after the two most powerful sons of Niall: Conall and Eógain.
The Battle of Magh Slécht took place at Magh Slécht in Ireland in 1256. The battle was part of a wider conflict between the O'Rourke rulers of Breifne and their traditional O'Reilly vassals over control of the kingdom. Both sides were assisted by their respective allies, the O'Connor kings of Connacht and their Burke opponents. The battle marks the point at which the Kingdom of Breifne was left permanently divided, creating West Breifne (O'Rourke) and East Breifne (O'Reilly).
