Who this is for: Anyone who’s wondered whether Ireland ever had a monarchy, and readers researching Irish history and mythology’s most notable rulers.
Key takeaway: Yes, Ireland had Irish kings and queens, spanning legendary figures like Sláine mac Dela through to the last native High King in 1198, but it has had no monarchy at all since becoming a republic in 1949.
Expert insight:
Stand on the Hill of Tara today and there’s very little to see structurally, just earthworks and a standing stone. That’s almost the point. The High Kings’ power was symbolic as much as territorial, claimed at a hilltop rather than enforced from a fortress, which tells you something real about how authority actually worked among Ireland’s early Irish kings and queens.

Quick facts:
- Ireland’s High Kingship was more a claim to symbolic authority than a single unified throne; real power remained regional for most of its history
- The last native High King, Ruaidrí Ua Conchobair, was forced to renounce the title following the Anglo-Norman invasion of 1169 to 1171
- Ireland has been a republic without a monarchy since 1949, and the Irish Free State that preceded it was established in 1922

Irish kings and queens ruled the island for thousands of years, some historical, some legendary, and many somewhere in between. The High Kingship at Tara claimed authority over the whole island but functioned more as a symbolic title than a single throne, and native kingship ended for good in 1198, when the last of Ireland’s High Kings was forced to renounce the role following the Anglo-Norman invasion.
This guide to Ireland’s Irish kings and queens covers who actually held these titles, the most notable queens in Irish history and mythology, and the two genuinely surviving Irish “kings” you can still visit today.
Who Were Ireland’s High Kings?
Ireland’s Irish kings and queens didn’t rule from a single unified throne so much as claim it, generation after generation, from the same hilltop seat.
Where the Idea Came From
Irish kings and queens claimed their authority from a seat at the Hill of Tara in County Meath, known as an Ard Rí, or High King. Because Celtic Ireland passed its history down orally rather than in writing, the earliest Irish kings and queens sit somewhere between history and legend, recorded only after Christian monks began writing Irish history down centuries later, not always neutrally. Kings who reigned before the fifth century are generally treated as legendary rather than historical, a period historians sometimes call “pseudohistory” for exactly that reason. Heritage Ireland’s guide to the Hill of Tara, the OPW-managed site itself, covers what survives there today, including the Lia Fáil.
The First High King
Irish mythology credits the Fír Bolg, who according to legend arrived in Ireland with roughly 5,000 people led by five brothers, with founding the line of Irish kings and queens that followed. The youngest brother, Sláine mac Dela, became the first High King but died within a year of taking the title. Several of his brothers followed him in quick succession, including two who reportedly died of plague, before Eochaid mac Eirc, considered the last genuinely capable Fír Bolg king, was defeated by the Morrígan, the Irish goddess of war and prophecy.
The Tuatha Dé Danann and the Lia Fáil
The Tuatha Dé Danann, a race of magical beings in Irish mythology, arrived next and won the kingship after their king Nuada defeated the Fír Bolg, though Nuada lost an arm in the process and, by tribal custom, could not rule while visibly unwell. Nuada later returned to the throne once fitted with a working silver arm. His successor Bres proved disastrous, aligning with the hostile Fomorians against his own people, until Nuada’s second reign restored order.
The Tuatha Dé Danann brought the Lia Fáil, the Stone of Destiny, to Tara as one of four legendary treasures. Tradition holds that the stone roared when the rightful king stood on it, though it’s said to have done so only once in later, more historical times: at Brian Boru’s coronation. ConnollyCove’s guide to the Tuatha Dé Danann covers this race in full.
The Last High King
Of all Ireland’s Irish kings and queens, Ruaidrí Ua Conchobair (Rory O’Connor) holds a particular distinction: he became the last native High King in 1166 and ruled for roughly three decades before the Anglo-Norman invasion of 1169–71 forced his renunciation of the title by 1198. From that point, no native Irish king or queen held authority over the whole island again, and Ireland’s Irish kings and queens after this were, without exception, imposed from England.
Henry VIII formally proclaimed himself King of Ireland in 1541, a title that passed through the Tudor and Stuart crowns, survived Cromwell’s conquest and the Williamite Wars, and lasted until the Kingdom of Ireland was abolished by the Act of Union in 1801. ConnollyCove’s history of Ireland covers this period, from the Norman invasion through independence, in full.
Legendary and Historical Irish Queens
Irish kings and queens include some genuinely formidable women, three of whom stand out clearly across both mythology and history.
Queen Maeve
Queen Maeve (Medb) ruled Connacht and is one of the best-documented rulers in Irish mythology, appearing throughout the Ulster Cycle. Determined to match her husband Ailill’s wealth exactly, she launched the Táin Bó Cúailnge, the Cattle Raid of Cooley, to seize Ulster’s prized bull and settle the imbalance. ConnollyCove’s full profile of Queen Maeve covers the raid and her connection to the wider Tuatha Dé Danann mythology.
Grace O’Malley, the Pirate Queen
Grace O’Malley (Gráinne Mhaol), a sixteenth-century Gaelic chieftain from County Mayo, commanded around 200 men and a fleet of galleys along Ireland’s west coast. ConnollyCove’s full profile of Grace O’Malley covers her life, including her connection to Westport House, her ancestral home in County Mayo, now home to a dedicated exhibition on her legacy.
Gormlaith Ingen Murchada
Gormlaith, born in County Kildare around 960 AD, was queen through two marriages, first to the Norse king of Dublin, later to Brian Boru himself. Tradition holds she encouraged her brother and son to turn against Boru at the Battle of Clontarf following their separation, making her one of Irish history’s more consequential political figures.
Other Notable Irish Kings and Queens
Beyond the High Kingship, several other Irish kings and queens shaped events without ever holding the high title itself.
Conchobar mac Nessa, King of Ulster and briefly Maeve’s husband, features heavily in the Ulster Cycle and is generally remembered as a wise, capable ruler despite that marriage’s failure.
Dermot MacMurrough, King of Leinster, is remembered less for his reign than for what it triggered: exiled after losing power to rival kings, he sought help from Henry II of England, directly setting off the Anglo-Norman invasion that would end native High Kingship within a generation. The nickname history left him with, “Dermot na nGall,” Dermot of the Foreigners, reflects how that decision was judged afterward.
Brian Boru, crowned at Cashel, remains the most celebrated of all Ireland’s Irish kings and queens, remembered for defeating a Norse-Leinster alliance at the Battle of Clontarf in 1014. According to tradition, Boru, a devout Christian, refused to personally fight on Good Friday, the day he was killed.
Ireland’s Surviving “Kings” Today
Two of Ireland’s Irish kings and queens genuinely still exist in title if not in power, both worth knowing if you’re travelling through their territory.
The King of Tory Island, off the Donegal coast, is a ceremonial role predating any formal record, filled by community tradition on an island with a population under 200. The role carries no legal authority but functions as the island’s spokesperson and informal welcome party for visitors. The last King of Tory, Patsy Dan Rodgers, died in 2018.
King Puck, crowned annually in Killorglin, County Kerry, is, genuinely, a goat. The Puck Fair, held each August and drawing an estimated 80,000 visitors, may trace back to the seventeenth century or earlier, possibly linked to the older Celtic harvest festival of Lughnasa. According to local tradition, a goat once broke from its herd to warn the town of approaching Cromwellian soldiers, and the festival honours that act. The fair’s animal-welfare practices, specifically holding the goat caged for the festival’s three days, have drawn criticism in recent years, worth knowing if the ethics of the tradition matter to you before visiting.
Does Ireland Have a Monarchy Today?
No. Ireland has had no monarchy of any kind since becoming a republic in 1949, and none of its Irish kings and queens, historical or legendary, have any modern legal successor. The path there ran through the First Dáil’s unilateral declaration of independence in 1919, formal recognition following the Anglo-Irish Treaty of 1921, and the creation of the Irish Free State in 1922, which became a full republic 27 years later.
Some families maintain ceremonial claims to historic royal lines. The O’Briens of Thomond trace descent from Brian Boru, and the O’Connors of Connacht from Ruaidrí Ua Conchobair, the last High King, though neither carries any legal standing today. Anyone curious about their own Irish ancestral connections can start with a genealogy resource like the John Grenham Irish ancestry database.
Conclusion
Ireland’s kings and queens span roughly three thousand years, from legendary Fír Bolg brothers through Brian Boru’s historical reign to a literal goat crowned annually in Kerry. Native kingship ended in 1198, and Ireland has had no monarchy of any kind since 1949, but the idea of Ireland’s Irish kings and queens never entirely disappeared from Irish life, it just changed what it meant.
