Episode 12 of Irish History Tales explores the Great Revolt of 1173–1174 and the profound impact it had on the Norman Conquest of Ireland. While Henry II battles rebellion across his Angevin Empire including revolts led by his own sons, the intervention of King Louis VII of France, and the invasion of England by William the Lion of Scotland, makes the Norman position in Ireland suddenly vulnerable.

The episode examines how Henry's crisis forced Strongbow and Hugh de Lacy to divert men and resources away from Ireland, creating an opportunity for Gaelic resistance. We follow Donal Mór O'Brien's offensive against Norman positions around Kilkenny, and the growing instability facing the Norman settlements.

We also explore the fascinating story of Donal Kavanagh, son of Dermot MacMurrough. Once an ally of Strongbow, Donal breaks with the Normans and emerges as a leading figure in the Gaelic resistance, launching devastating attacks against Norman settlements in Leinster. Along the way, we examine the deaths of Murchad MacMurrough and Tiernan O'Rourke, and consider how these events may have influenced Donal's changing attitude towards Norman rule.

As Henry II fights for survival overseas and Gaelic rulers seize the initiative at home, the future of Ireland looks remarkably uncertain. For the first time since the arrival of the Normans, it appears possible that the conquest could be reversed.

Episode 11 explores the rise of Hugh de Lacy and the Norman conquest of Meath following King Henry II’s departure from Ireland in 1172. Determined to prevent Strongbow from becoming too powerful, Henry grants the vast and strategically important Kingdom of Meath to his trusted lieutenant Hugh de Lacy, creating a new Norman lordship at the very heart of Ireland.

The episode examines why Meath was one of the most valuable kingdoms in Gaelic Ireland, the Norman strategy of castle building and colonisation, and the growing rivalry between Hugh de Lacy and Strongbow. We also explore the weakening authority of Rory O’Connor as High King, the collapse of the great anti-Norman coalition, and the continued political manoeuvring of powerful rulers such as Tiernan O'Rourke.

At the centre of the story is the dramatic confrontation between Hugh de Lacy and Tiernan O’Rourke, King of Bréifne. Drawing on both Norman and Gaelic sources, we examine the disputed meeting at the Hill of Ward, the controversial death of O’Rourke, and the very different versions of events preserved by medieval chroniclers. The episode concludes with the death of one of the most important Gaelic kings of the age and explores how his killing marked a major escalation in tensions between the Normans and the Irish.

Episode 10 of Irish History Tales explores the arrival and impact of King Henry II in Ireland in 1171–1172, marking a major turning point in the Norman Conquest. After the victories of Strongbow (Richard de Clare) and the growing power of the Norman lords, Henry lands in Ireland to bring the invasion under direct royal control and prevent Strongbow from creating an independent kingdom.

The episode examines the submissions of Gaelic kings and the beginning of the Lordship of Ireland. It also explores the Synod of Cashel and the growing influence of the English crown over the Irish Church, linking these developments to the controversial Papal Bull Laudabiliter.

We also explore whether the murder of Thomas Becket influenced King Henry II's decision to invade Ireland. Key figures such as Hugh de Lacy, Strongbow, and Henry II are discussed as the first phase of the Norman Conquest comes to an end and a new political era begins. The episode also explores how Norman rule would gradually reshape Ireland through new systems of lordship, trade, agriculture, religion, and royal administration.

In this bonus episode, we step away from the main narrative to examine one of the most important sources for the Norman Conquest of Ireland: The Song of Dermot and the Earl.

This Anglo-Norman French verse chronicle gives us some of the most vivid details of the invasion — from Dermot MacMurrough’s exile and the arrival of the Normans, to the capture of Waterford, the fall of Dublin, Rory O’Connor’s siege, and the growing power of Strongbow.

But how reliable is it?

We explore who may have been behind the text, the possible role of Dermot’s interpreter Maurice Regan, what the source contains, and how its pro-Norman bias shapes the story it tells.

In this bonus episode, we cover:

• The Song as a Primary Source
• Who was Maurice Regan?
• What events the poem describes in vivid detail.
• Bias and Propaganda
  

Why historians must compare The Song with the Irish annals, Gerald of Wales and modern scholarship.

In this episode, the Norman Conquest of Ireland enters another unstable and violent phase.

After breaking Rory O’Connor’s siege of Dublin, Strongbow turns south towards Wexford, hoping to rescue Robert FitzStephen, one of the first Norman leaders to arrive in Ireland. But Wexford has rebelled, FitzStephen remains a prisoner, and Strongbow quickly discovers that victory at Dublin has not secured his position in Leinster.

As he marches through hostile territory, Strongbow faces an ambush before reaching Wexford too late to recover FitzStephen. The failure exposes just how fragile the Norman foothold still is. They hold important towns and strongholds, but much of the surrounding countryside remains contested, dangerous and beyond their control.

Strongbow then seeks new allies, turning to Donal Mór O’Brien of Thomond, a surprising partner, given O’Brien had recently stood with Rory O’Connor outside Dublin. But family ties, political opportunity and local rivalries bring the two men together for a campaign against Ossory.

We explore the dramatic Ossory episode, where Maurice de Prendergast protects the king of Ossory after giving him safe conduct, even killing warriors from Donal Mór O’Brien’s side to defend his oath. It is one of the most revealing moments in the story, showing that the Norman invasion was not a simple conflict between two fixed sides, but a world of shifting alliances, personal honour, betrayal and survival.

Meanwhile, across the Irish Sea, King Henry II is watching closely. Strongbow has survived Rory O’Connor and held Dublin but that success now makes him dangerous to his own king.

In this episode, we cover:

• Strongbow’s March to Wexford: Why the victory at Dublin did not end the crisis.
• Robert FitzStephen’s Capture: How rebellion in Wexford exposed Norman weakness.
• Resistance in Leinster: Why Strongbow still did not control the countryside.
• The Ossory Campaign: Strongbow, Donal Mór O’Brien and the attack on Mac Gillapatrick.
• Maurice de Prendergast’s Oath: The remarkable episode where honour overruled politics.
• The Shadow of Henry II: Why Strongbow’s survival forced the English king to intervene.

In this episode, the Norman Conquest of Ireland reaches one of its most dramatic turning points.

After Dermot MacMurrough’s death, Strongbow’s position in Ireland becomes dangerously unstable. His claim to Leinster is resisted, Dublin is isolated, and Rory O’Connor, the High King of Ireland, gathers a great Gaelic coalition to drive the Normans out.

As Rory’s forces surround Dublin from several directions, the Norman garrison begins to run short of food. To make matters worse, news arrives that Robert FitzStephen has been captured in Wexford, one of the original Norman footholds in Ireland. Strongbow is trapped, under pressure, and facing the possible collapse of the entire invasion.

We explore Strongbow’s extraordinary offer to become Rory O’Connor’s man and hold Leinster from the High King. A moment that raises one of the great “what ifs” of Irish history. Should Rory have accepted? Could Strongbow ever have remained loyal? Or was the offer impossible to accept within the political world of Gaelic Ireland?

When negotiations fail, the Normans launch a desperate sortie from Dublin. Milo de Cogan, Raymond le Gros and Strongbow lead a sudden attack on the besieging forces, breaking Rory’s great coalition and saving the city.

But victory does not mean security. Wexford has rebelled, FitzStephen remains a prisoner, Leinster is unstable, and across the Irish Sea, King Henry II is preparing to intervene.

In this episode, we cover:

• Rory O’Connor’s Great Coalition: How the High King surrounded Dublin with forces from across Ireland.
• Strongbow’s Crisis: Food shortages, isolation, and the threat of total collapse.
• The Offer of Fealty: Why Strongbow offered to hold Leinster from Rory O’Connor.
• The Sortie from Dublin: How the Normans broke the siege with a sudden counterattack.
• Wexford and FitzStephen: The rebellion that exposed how fragile the Norman position still was.
• The Shadow of Henry II: Why Strongbow’s survival made him both useful and dangerous to the English king.

In this episode, the Norman Conquest of Ireland enters a dangerous new phase.

Dermot MacMurrough is dead, but the consequences of his choices are only beginning to unfold. Strongbow now claims Leinster through his marriage to Aoife, but that claim is rejected by many within Leinster and viewed with alarm by Irish kings across the island.

We also reflect on Dermot’s dark and divisive reputation in Irish historical memory. Was he simply the man who “invited the Normans in,” or was he a ruthless but typical product of a violent political world? From the infamous attack on the Abbess of Kildare in 1132 to the hostages given to Rory O’Connor, we explore why Dermot remains one of the most hated figures in Irish history.

Meanwhile, Dublin faces a dramatic attempt at restoration. Ascall Mac Torcaill, the former Norse-Gaelic king of Dublin, returns by sea with warriors from the Isles and Man, determined to reclaim his city. But Milo de Cogan and the Norman garrison are ready.

In this episode, we cover:

• Dermot’s Reputation: Why MacMurrough still provokes such strong reactions today.
• Strongbow’s Claim to Leinster: How a marriage alliance turned mercenaries into conquerors.
• The Return of Ascall Mac Torcaill: The Norse-Gaelic attempt to retake Dublin by sea.
• The Fall of Norse-Gaelic Dublin: Why Ascall’s execution marked the end of an era.
• The Gathering Storm: How Rory O’Connor prepared to confront the Norman threat.

In this episode, the Norman Conquest of Ireland reaches a pivotal turning point.

After reclaiming the Kingdom of Leinster and launching a vengeful campaign against his bitter rival, Tiernan O’Rourke, Dermot McMurrough’s ambitions for the High Kingship are cut short. We explore the dramatic final months of MacMurrough’s life, his controversial life ending at Ferns in 1171, and the "insufferable disease" described by the annals of the time.

With the King of Leinster gone, the power vacuum changes everything. Strongbow finds himself transformed from a mercenary ally into a dangerous claimant to Irish lands, a move that puts him on a collision course with King Henry II. We also dive into the mystery of Laudabiliter: the controversial papal document that provided the legal and religious pretext for the English intervention in Ireland. Was it a genuine mandate from the only English Pope in history, or a convenient forgery?

In this episode, we cover:

• The Meath Campaign: Why the formidable Norman cavalry struggled in the Irish woodlands.

• The "What Ifs" of History: How King Henry II’s revocation of permission nearly ended the invasion before it began.

• The Death of Dermot MacMurrough: Fact vs. folklore regarding his final days and his legacy in the Irish Annals.

• Laudabiliter & The Papacy: A deep dive into the document that justified a conquest.
